The engine oil cooler inlet pipe were not set probably after the new oil cooler has been replaced! Check the different on 3:45 and after the installation on 6:17 it looks like it did not got placed correctly in its place! If the engine were to be stressed with high altitude in the future the pipe differently will go out of its place a little then start to leak all the coolant water out!
Thanks for watching closely. I had a look at the the 2 time points the camera has been moved which I think changes the perspective. I can't exactly remember that repair or that filming but sometimes when I film things are done twice, once for the camera and once where I get my head and arms in there to ensure it was done correct. I pressure test any cooling system repair so I am confident when the car dives off as to have no leaks. Hey thanks again for noticing and pointing it out. Will pin this comment at the top. Cheers
Very good video! Just what I needed as local main dealer quoted £700+ for the job, while the parts were about £130!!! The video really boosted my confidence... thank you!!
Great video. Step by step is easy to follow... I was thinking of replacing the oil cooler in my Holden Cruze but after watching this hhmmm, not so sure.. too much to do.
Thanks for video. This is just what I wanted. Getting oil in water bottle and I need change oil cooler and/or seals. I was going to do it but not in the right order. After watching this I can have it done quicker. Thanks for saving me at least half a day. Back on the road sooner.
great video. very clear and gave great detail on the assembly and I liked the little tips. the image is extremely clear and not shaky like some. thanks for your work it was so easy to do this.
Thank you for your help. I have just removed and rebuilt the unit from my Astra SRi vvt with the Z18xer engine. Unfortunately the access was not as good as the model you have but that's life! You were spot on with your assessment of how long it lasts. Mine was just on 70k miles. 👍🏼
Nice video Just done this job on a 1.8 Vectra almost the same but the expansion tank is at the back Did change the whole housing only the cooler The vid was very helpful 👍
You will need a special 22mm 'o2 sensor removal socket' to get the o2 sensor out. To my knowledge, the cable to it is FIXED. It's unlikely you'll have a spanner that can get in there unless you take the radiator out or in my case the a/c tubing. Watching another video, you may even have to put a hose clamp on the socket once it is in place, to stop it from opening up when twisting - that's how hard they can be to get off.. crowfoot spanner *might* open up also or could struggle to get in there - try it if you have one but I wouldn't buy specifically..
Thanks for the video mate! I'm about to order parts. Just wondering if your oil cooler and seals are aftermarket? Do you mind sharing where you got them from?
Yep, exactly same issue and symptoms (but way worse sludge). All replaced now and seems sorted. Loads more difficult to do on mine than yours though - O2 sensor seized, exhaust nuts seized, couple of manifold bolts seized, top rad hose welded to the engine, etc. Luckily the power of fire, a knife and a 10mm impact socket helped.
Thanks for the video !!! I’m about to do the same on my 2013 Chevy sonic lt 1.8 Bought brand new from the dealer and has 112,000 miles on it now and we just started seeing oil in the reservoir..... doesn’t look like 2 bad of a job ! Thanks
Killa Watt Garage will you always see oil in the coolant res? Because my dealer is telling me my oil cooler is leaking but there’s no oil in my coolant. Just a smell when I start my car. My Cruze is a 2015 with only 60k on it
Tip 1: use penetrative spray on the 3 bolts that hold the cat to flex pipe before undoing them. And wait overnight. Found out the hard way and snapped one of the stud's off. Tip 2: if the oxygen sensor won't budge, where it mounts into manifold use a heat gun on there for a few minutes , mine would not budge no matter what , with the heat gun it just released easy. Tip 3: dont go to repco or supercheap to find a simple sump plug o ring for the cruzes , they don't carry them🙄
Used a cold chisel and hammer to hammer out the remaining broken stud (the stud's are only pressed in and only pressed in one way so hammer from thread side ). Than got a bolt of matching size to the other studs and used that in place. The length of bolt was abit longer so cut it to the same length as the other two. When you go back to put on, and tighten the nut the bolt head will want to spin so just hold the bolt head to tighten nut. No dramas and works perfectly 👍
@@jmad123 I have done both. Takes a little longer to remove the oil cooler then disassemble and replace the seals, but its often cheaper. Either way will fix the problem.
I would suggest using the radiator butterfly drain. The engine bay will stay cleaner, and you wont subject yourself and the rubber and plastic parts, including any wiring, to degreaser which is notoriously bad for non metallic parts. From my experience even cleaners that claimed to be safe were not. Seems Chevy and the dealers are stringing ppl along when they have coolant loss. Acting as if they cannot find the location of obvious coolant loss.
Great video. But here comes the question how did you diagnose that it is the oil cooler and not the head gasket or Oil Pump gasget? In addition what brand is the oil cooler? Also noticed that you are not using torque wrench which I think is pretty important.
Hi and thanks for the questions. Sorry for the long answer but these cruze's often suffer Head Gasket issues too so it is important to know what to fix and not waste your money. Answer 1: 'Typically' a blown head gasket has coolant mixing with oil and you see the 'milkshake' consistancy under the oil cap, where as this is oil mixing with coolant. I know that sounds like semantics but it is different. Coolant pressures are at a maximum of about 18-20psi while oil pressure can be 60psi+. In the oil cooler you have these 2 fluids flow around each other so there is an exchange of heat, a failing seal here will see the oil pressure find it's way into the coolant. Hence you see the oil contamination in the coolant bottle. A head gasket seals coolant, combustion pressure, oil drain back holes and a single oil pressure passage to delivery oil to the top of the cylinder head. When this fails often coolant at 18-20psi will find is way to the oil drain back hole which has no pressure and then coolant mixes with oil in the sump and we see evidence of this under the oil cap. This is usually accompanied with compression lost into the cooling system resulting in coolant over pressuring and lost of coolant. I also use a test like this th-cam.com/video/91zPQ3G1ujE/w-d-xo.html which measures CO2 levels in the cooling system which is an indication of combustion gases leaking into the cooling system. Answer 2: For this video I used an aftermarket cooler as they are plentiful and very cheap compared to genuine. There are multiple brands all with good warranty periods. Answer 3: Yes Torque setting are best to use. I re-looked these up to answer you question but don't have a listing. I would suggest around 8Nm however in my defence as a mechanic you get good at feeling the force you are tightening with. Hope this answers your questions, happy o help.
Hi, @@killawattgarage Big thanks for your time and answers. I clearly got your point but there is something I think it is worth to consider. In my case I have changed the oil cooler seals before 70000 km. And now except the oil in coolant I have an external oil leaking for which I cannot clearly see the starting location. Have you got a case with defective oil cooler with both external and internal leak? My research so far points me to the oil pump gasket which also could cause such behavior. Please check the links below and let me know your thoughts. mechanics.stackexchange.com/questions/32999/astra-h-oil-found-in-coolant th-cam.com/video/kGsalTM-2Sc/w-d-xo.html
@@LyubomirL Yes these can definitely leak oil externally as well.They typically don't last long. High heat and pressure really take there toll on the seals.
This was really informative. It taught me that I cannot do this myself to my holden barina which has the same configuration of parts as the vid demonstration 😢
4:02 The mental right hand (Coolant Pipe) that feeds into the (thermostat intake coolant housing,) can I just replace that without removing the the exhaust manifold?
Pretty impressive! I can't see how else you could improve without introducing things that slow down repair work. Maybe just a second GoPro so you can leave one set up where you know you'll be back? I film with a DSLR and it can be a chore sometimes.
I have a 2013 1.8L Sonic and hadn't ever seen oil in coolant, but today when I was driving, suddenly engine started to make noises, so I pulled out immediately, and I was shocked when I saw coolant reservoir completely full of oil that engine was almost empty of oil. Do you think oil cooler seal could be the problem? Is there any other possibility? Before that my car was running very good. Thanks for your comments.
Great video thank you. Question I have mine torn down to the cooler and realized the bolt underneath (where the leak appears to be) was very loose. Do you think I should tighten the bolt and hope it won't leak and reassemble or continue the replacement?
Great video. Will be attempting this next week . Just one question what is the last process of refilling the coolant and purging air out off the system ? Dont want to or need to flush it just refill. Thanks
I used a ton of penetrating spray, and some brake clean for surfaces. Turned it on and had that normal smoke. Test drove and coolant light went off. Shut it off and let it cool and had it idling again. No leaks other than the small drops of oil it had from other seals but suddenly it started smoking again no light though. Should I be worried?
Hey Killa Watt Garage! Awesome channel & thanks for the video. I have a 2015 Barina X with the 1.6 litre engine and I’ve just had the oil cooler replaced at a Holden Dealership with genuine parts. The coolant reservoir was also cracked, the O rings on the reservoir cap was broken so that was replaced as well, the air bleed pipe to the throttle body had to be replaced as it had a coolant leak as well. I have 2 questions: 1) If there is no oil in the coolant, how do the mechanics know to change the oil cooler? Do they start to leak oil or coolant? Or have they just done it because it’s a common thing that goes after a while? Or do they show signs of old age? 2) Do you think this could be the start of some expensive repairs in the future with this car? Are there other things that start to go with these motors at this age? The car is 7 years old now and I have a feeling there could be more issues arising soon. Cost me heaps of money to fix and I don’t want to get caught out again with a big bill in a few months. I don’t have the skills to repair these things myself. Any advice would be really appreciated. Thanks 🙏 🚗
I’m getting the rocker cover gasket done next week as well. I’ve had the spark plugs and coil pack done as well. ✅ so I’m trying to stay on top of it but the bills are adding up. Thanks
Thank you for this great video. Do you think that faulty cooler gasket and oil in the coolant and coolant in the oil can stop heating to work? Mine has this symptoms and I'm thinking to change that too.
If you have oil contamination in the coolant then you will have very low flow through the heater core and no heat in the car. Start by checking the coolant quality and level.
I found that the seals used in the coolant pipes on the oil cooler weren’t sealing and started leaking before the system was pressurised. Do you have any tips or a specific seal kit you used?
how do I tell if its the oil cooler thats gone or a blown head gasket? ... Just bought a cruze thats not running and has oil in the resevoir but no oil in the radiator yet.
Blown head gaskets are common with these cars. If it's not running I would spend the time to do a compression check and go from there to determine whats wrong. If the head has to come off it's really easy to access the oil cooler and a smart move to replace it then. Let me know how it goes. Thanks for the question.
I got oil in coolant reservoir. A little oil coming out from back of the cooler. After watching this I'm sure the gasket will be bad . My question is what where the engine performance symptoms from this? My car seems like it doesn't have power when going up on a hill ? Is this why I got no low oil pressure according to a receipt left in car from last owner
Hey can I get some help! When I put my new one in it snapped the little metal ring where the coolant goes on both sides, then it did it again when I tried to put the old one in. Is this because I’m not lining it up correctly? Or am I tightening it too hard? It was easy to tighten when ut snapped, and when I turned my car on al the coolant came out
do u recommend to do a radiator flush with the change of the oil cooler since coolant got mixed up with the oil?. Also, any tips you forgot to mention on the video?. Thank you.
Yes you will need to flush the cooling system. Depending on how bad/long the oil cooler has been leaking will help you decided the best method. I suggested just using water initially as it may take a couple of flushes. After most of the emulsified oil is out use a radiator flush additive to help clear it all. I also suggest removing the coolant bottle and flushing it separately. If oil has been in the cooling system a long time it can effect the rubber hoses so be sure to check their condition, they go all soft and saggy when badly effected. Hope this helps.
I can not believe how they ripped me off because of this. I had the exact same thing on chevy cruze and mechanic said, "well it mixed oil and coolant so maybe it have blown head gasket or cracked head so you don't wanna take risk, the cylinder head must go off". Damn him, all car needed was a new oil cooler, new oil and new coolant.
Hello from Canada, Just wanted to Thank you I was freaked out to do this job, but watching this short, clear and detailed awesome video just gave me the confidence to do this! I will order a new cooler right now on amazon but my only problem I dont know how to find all those seals on the 3 metal hose around the cooler.... Do you have a list of them, I cant find a kit with all those or even a list with part numbers.. Once again Thanks you saved my young family a bunch of money with these explanations
Thanks for the video! My local mechanic charged me $1300NZD to "fix" the cooler, but now it's broken again -_- I can't find an F16D4 cooler online, but I can find the F18D4. Are they the same thing?
What tool did you use to remove exhaust manifold and what were the size of the bolts? Chevy has bolts that require esocket set. Just wondering what to use if you dont have esocket set?
From memory they were 10 mm nuts. Torx sockets can be brought fairly cheap. As a hack you can use 12 point sockets but I wouldn't suggest it. Thanks for the question.
Hey mate, can the black plastic oil filter relief valve be unscrewed from the oil cooler housing without taking the oil cooler completely off? It has a hex shaped top so I assume it would just unscrew?
Is it possible to seal off those coolant tubes and that oil route it out to an external air oil cooler then back into the engine? Just to eliminate that Messy cooling set
What are you using to lubricate the o-rings. I got mine all apart. Just waiting on parts to come,and I'm going to reassemble. Just wondering whats a good lube to use on orings. Thank you
@@killawattgarage ok i got silicone lubricant it says for o rings. Use that or coolant. Guess it don't matter right. Like u said just as long as there not dry right. Thank you for the help and video
I changed the whole oil cooler. My problem is the water is leaking through the water cooler pipe that is connected under the thermostat. Can I use sealant near the Oring when I connect the water cooler tube? Thanks.
Why you didn't change the exhaust gasket? I will do the same operation to mine, and i ordered another exhaust gasket. It's a chance that i could use the old one?
Do you need to wet the gaskets on the oil cooler with motor oil that goes onto the engine surface...like you would when changing an oil filter? What are you lubricating the O-rings with on the cooler pipe?
This is an excellent tutorial. I did notice green coolant (Not Dexcool) I've heard that the Dexcool is harsher on the cooling system. Especially the hoses. Do you know if that is true?
Garbage GM isn't satisfied with just all of the regular cooling system failing, they're also going to trash this lol. GM should be DISSOLVED and execs imprisoned for life.
great video mate! thanks ! mine is a 1.6L turbo and looks bit different to the one in your video. do u think the oil cooler is still at the same place under the exhaust manifold ? I cant see a oil filter near by though!
What started out as some sludge in the coolant reservoir is now a very oily substance. Do you think it’s still the oil cooler ? Oil in the engine is fine.
I have done a few of these so I am getting quick, but allow yourself a couple of hours and you will get it done easily. The bolts securing the bottom of the manifold to a bracket on the block are a Torx head bolt. I don't remember the size?? Thanks for the questions.
I thought my head gasket leaking when found milky stuff in the radiatot reservoir....it is oil cooler unit couse the problem...but that oil cooler location is hard to tackle...
Lots of flushing. I just use water rather than coolant and drive the car 10-15 minutes and flush again and again. If really bad a dishwasher cleaning tablet in with the water and then a short drive, this does a really good job. Also take the reservoir off and rinse it. It takes awhile to get it clean. Also make sure the hoses are all still good.
After changing my thermostat housing, i get heat again but the radiator fan is still on full blast. I got yet another thermostat housing to replace the faulty one but found oil in my coolant this time. Also i noticed my oil light dings when I idle after driving for a little while. And cruise control quit after as well. I'm not sure what i could have done to cause this. Any ideas? I thought maybe i knocked something loose on the oil cooler. 2012 sonic 1.8L manual. Thanks, great video too by the way. Maybe I'll attempt to change the cooler gaskets as well.
always when replacing thermostat also replace the one $10 temp sensor on the left side of the radiator as it has one there and that was the one causing me to have fan on all the time.
Most people are going to not be able to just undo that O2 sensor .. a lot of cars the sensor is seized on it .. unless you have a butane torch you will struggle … so I had the 1.8 litre I left O2 sensor in place I just unplugged wire .. you remove the fan the electric fan is easy to remove two bolts up top .. then remove the front grill .. under there is the cross member 3 bolts on either side remove three bolts on air intake side and also one torx screw .. then once air intake pipes out .. two bolts to remove fan shroud .. then their is a plug under the car for fans .. then pulling out fan shroud one more wire just plugged into plastic .. manifold then slides out with no problem .. you would have been better off removing the fan shrouds .
Loved the video. Just had our oil cooler replaced 4 days ago at our local Ex-Holden dealer. Since then it's leaking coolant from the smaller of the 2 pipes on the left. Checked the invoice (Over $1500) and only got charged for 2 O'rings for the outlet pipe. Do you believe they should have replaced 6 instead of only 2?
Sorry for the slow reply. If the o Rings are in good condition they can be reused but as they are cheap I would replace them, and it avoids issues later. Take it back and get them to fix the leak.
I have chevy cruze1.6L 2013 model, on the dash it complain of oil and the is having enough oil, is there anything wrong with the oil cooler, please help.
One simple question? How do you get rid of all the oil that's still inside the coolant system after you've repaired or replaced the oil cooler/Oil cooler gasket?
Flush Flush and Flush. You can get additives to help. Dishwashing liquid is actually effective but can be super bubbly and needs lots of flushing to get it out of the system too.
Thank u so much, found my issue. Oil in the radiator resivor and I was losing radiator fluid. Couldn't I just change the seals in the cooler? Or the whole thing should be replaced. Thank u a bunch 😌
Price of the part will vary. You also will need new coolant and it's a good time to do an oil change as well. These prices will vary country to country. The Oil Cooler replacement shouldn't be any more than 2 hrs of labour.
@@killawattgarage thanks for the reply. I'm taking my astra to my mechanic in England he says around 1.5/2 hours labour at £60 hour. I wonder how much the part will cost
Thank you for this video, it's just awsome.. I do the same ila my car, thank you man.. But i have an other problem, I noticed that in my Sonic when I accelerate I hear like a sound of coolant circulating inside the car. is it normal or is a part defective ?
It means that there is some air in the cooling system. Make sure that you can feel heat from the heater when the engine is warm. The sound is often more noticeable on a cold engine. Keep watching the coolant levels as it will settle/drop after some time. They are a hard system to purge the air from. In the factory they are vacuum filled and if you have access to this tool it is the best way. th-cam.com/video/5ZFe1GUzXGw/w-d-xo.html
thank you for your replay sir, yes I think that I have some air in the cooling circuit, I bleed the system 3 times and I changed the thermostat and the tank cap, and always the same... :/ , just one last little question, when the engine is hot and I open the tank cap, is it normal for the coolant to overflow?
give it a few heat and cooling cycles and it should be cleared up. If not there may be blocked hoses/heater core etc. Check the little hose that goes to the throttle body. Make sure it is clear and can flow.
It was perfectly portioned to catch the coolant LOL! It has a flex joint in there so I would have been able to drain most of it back out, but a good heads up to all.

Big thanks for your time and answers. I clearly got your point but there is something I think it is worth to consider. In my case I have changed the oil cooler seals before 70000 km. And now except the oil in coolant I have an external oil leaking for which I cannot clearly see the starting location. Have you got a case with defective oil cooler with both external and internal leak? My research so far points me to the oil pump gasket which also could cause such behavior. Please check the links below and let me know your thoughts. mechanics.stackexchange.com/questions/32999/astra-h-oil-found-in-coolant
th-cam.com/video/kGsalTM-2Sc/w-d-xo.html
@@LyubomirL Yes these can definitely leak oil externally as well.They typically don't last long. High heat and pressure really take there toll on the seals.
This was really informative. It taught me that I cannot do this myself to my holden barina which has the same configuration of parts as the vid demonstration 😢
4:02 The mental right hand (Coolant Pipe) that feeds into the (thermostat intake coolant housing,) can I just replace that without removing the the exhaust manifold?
Yes, you sure can!
Very nice explanation and information.
Glad it was helpful!
Thanks heaps mate. Perfect instructions. Made this an easy job.
Appreciate this video great help!
Happy to help
Well filmed!
I do all my filming with a single GoPro camera and a shop light. I really need to upgrade but have no idea of what camera would suit.
Pretty impressive! I can't see how else you could improve without introducing things that slow down repair work. Maybe just a second GoPro so you can leave one set up where you know you'll be back?
I film with a DSLR and it can be a chore sometimes.
I have a 2013 1.8L Sonic and hadn't ever seen oil in coolant, but today when I was driving, suddenly engine started to make noises, so I pulled out immediately, and I was shocked when I saw coolant reservoir completely full of oil that engine was almost empty of oil. Do you think oil cooler seal could be the problem? Is there any other possibility? Before that my car was running very good. Thanks for your comments.
Sorry for the slow reply but sounds like the oil cooler seals for sure. Hope its sorted by now.
Great video thank you. Question I have mine torn down to the cooler and realized the bolt underneath (where the leak appears to be) was very loose. Do you think I should tighten the bolt and hope it won't leak and reassemble or continue the replacement?
Just wondering if tightening that one bolt fixed your leak or did you have to replace the oil cooler?
Great video. Will be attempting this next week . Just one question what is the last process of refilling the coolant and purging air out off the system ? Dont want to or need to flush it just refill. Thanks
I used a ton of penetrating spray, and some brake clean for surfaces. Turned it on and had that normal smoke. Test drove and coolant light went off. Shut it off and let it cool and had it idling again. No leaks other than the small drops of oil it had from other seals but suddenly it started smoking again no light though. Should I be worried?
Hey Killa Watt Garage! Awesome channel & thanks for the video. I have a 2015 Barina X with the 1.6 litre engine and I’ve just had the oil cooler replaced at a Holden Dealership with genuine parts. The coolant reservoir was also cracked, the O rings on the reservoir cap was broken so that was replaced as well, the air bleed pipe to the throttle body had to be replaced as it had a coolant leak as well. I have 2 questions:
1) If there is no oil in the coolant, how do the mechanics know to change the oil cooler? Do they start to leak oil or coolant? Or have they just done it because it’s a common thing that goes after a while? Or do they show signs of old age?
2) Do you think this could be the start of some expensive repairs in the future with this car? Are there other things that start to go with these motors at this age? The car is 7 years old now and I have a feeling there could be more issues arising soon. Cost me heaps of money to fix and I don’t want to get caught out again with a big bill in a few months. I don’t have the skills to repair these things myself. Any advice would be really appreciated. Thanks 🙏 🚗
I’m getting the rocker cover gasket done next week as well. I’ve had the spark plugs and coil pack done as well. ✅ so I’m trying to stay on top of it but the bills are adding up. Thanks
I found that there are 5 bolts securing the oil cooler instead of 4. One bolt was right under the oil filter on right side.
Thank you for this great video. Do you think that faulty cooler gasket and oil in the coolant and coolant in the oil can stop heating to work? Mine has this symptoms and I'm thinking to change that too.
If you have oil contamination in the coolant then you will have very low flow through the heater core and no heat in the car. Start by checking the coolant quality and level.
Is it necessary to have the radiator cleaned and replace the thermostat and water pump?
I found that the seals used in the coolant pipes on the oil cooler weren’t sealing and started leaking before the system was pressurised. Do you have any tips or a specific seal kit you used?
Holly bull manure I am glad I have a good mechanic .
how do I tell if its the oil cooler thats gone or a blown head gasket? ... Just bought a cruze thats not running and has oil in the resevoir but no oil in the radiator yet.
Blown head gaskets are common with these cars. If it's not running I would spend the time to do a compression check and go from there to determine whats wrong. If the head has to come off it's really easy to access the oil cooler and a smart move to replace it then. Let me know how it goes. Thanks for the question.
Good video mate, I have an oil cooler and water pump to do and this has helped out big time
Glad it helped
I got oil in coolant reservoir. A little oil coming out from back of the cooler. After watching this I'm sure the gasket will be bad . My question is what where the engine performance symptoms from this? My car seems like it doesn't have power when going up on a hill ? Is this why I got no low oil pressure according to a receipt left in car from last owner
A leaking oil cooler wont show up as low power or any other drivability issue.
Great video! How the hell do you get that O2 sensor out? Special tool required?? I don't have a spanner I can fit in there..
Excellent Job. Thanks a million.....
You're welcome!
Changing the oil cooler is not s problem, pretty straightforward but matching up all those darn rubber o-rings is a pain.
Definitely
Hey can I get some help! When I put my new one in it snapped the little metal ring where the coolant goes on both sides, then it did it again when I tried to put the old one in. Is this because I’m not lining it up correctly? Or am I tightening it too hard? It was easy to tighten when ut snapped, and when I turned my car on al the coolant came out
do u recommend to do a radiator flush with the change of the oil cooler since coolant got mixed up with the oil?. Also, any tips you forgot to mention on the video?. Thank you.
Yes you will need to flush the cooling system. Depending on how bad/long the oil cooler has been leaking will help you decided the best method.
I suggested just using water initially as it may take a couple of flushes. After most of the emulsified oil is out use a radiator flush additive to help clear it all. I also suggest removing the coolant bottle and flushing it separately. If oil has been in the cooling system a long time it can effect the rubber hoses so be sure to check their condition, they go all soft and saggy when badly effected. Hope this helps.
Hello @@killawattgarage,
Can you do a video on how to do coolant flush specifically for the 1.8 L engine?
I can not believe how they ripped me off because of this. I had the exact same thing on chevy cruze and mechanic said, "well it mixed oil and coolant so maybe it have blown head gasket or cracked head so you don't wanna take risk, the cylinder head must go off". Damn him, all car needed was a new oil cooler, new oil and new coolant.
oh dear! sorry to hear this!
Hello from Canada, Just wanted to Thank you I was freaked out to do this job, but watching this short, clear and detailed awesome video just gave me the confidence to do this!
I will order a new cooler right now on amazon but my only problem I dont know how to find all those seals on the 3 metal hose around the cooler.... Do you have a list of them, I cant find a kit with all those or even a list with part numbers..
Once again Thanks you saved my young family a bunch of money with these explanations
Well Im still searching and cant find a kit with all those pipes o rings.... Anyone knows please? Thanks
typically they come with the oil cooler. Generic O rings from any parts store will work.
Thanks for the video! My local mechanic charged me $1300NZD to "fix" the cooler, but now it's broken again -_-
I can't find an F16D4 cooler online, but I can find the F18D4. Are they the same thing?
What tool did you use to remove exhaust manifold and what were the size of the bolts? Chevy has bolts that require esocket set. Just wondering what to use if you dont have esocket set?
From memory they were 10 mm nuts. Torx sockets can be brought fairly cheap. As a hack you can use 12 point sockets but I wouldn't suggest it. Thanks for the question.
How did you find the o rings for the cooling pipes which connect to the oil cooler? Or a complete gasket kit would be fine to ofcourse
Any good parts store will have these O Rings, just take the old one in and they can measure it up or you can buy genuine and pay heaps more $$$.
HELLO I HAVE QUESTION MY chevy 13 eco its leaking from this part oil coolant .should put new seals rings o should i buy the whole colant part ?
Hey mate, can the black plastic oil filter relief valve be unscrewed from the oil cooler housing without taking the oil cooler completely off? It has a hex shaped top so I assume it would just unscrew?
From memory I would assume yes. There is nothing from the engine side of the oil cooler that would need to be undone.
Did you drain the Coolant first. Or just let it spill out as you were removing the hoses that hold coolant.
Drain it first but there is alway plenty left in the lines and block etc. hence the mess I made
Is it possible to seal off those coolant tubes and that oil route it out to an external air oil cooler then back into the engine? Just to eliminate that Messy cooling set
What are you using to lubricate the o-rings. I got mine all apart. Just waiting on parts to come,and I'm going to reassemble. Just wondering whats a good lube to use on orings. Thank you
The O rings on the coolant pipes I dipped into coolant and assembled. As long as its not dry you wont have any issues.
@@killawattgarage ok i got silicone lubricant it says for o rings. Use that or coolant. Guess it don't matter right. Like u said just as long as there not dry right. Thank you for the help and video
@@tylerwilliams786 Correct
@@tylerwilliams786 Все смазки на нефтяной основе. Правильнее будет окунуть в антифриз и сразу устанавливать на место.
Whats its the socket size and type for the manifold cover bolts? Cant find info anywere
I changed the whole oil cooler. My problem is the water is leaking through the water cooler pipe that is connected under the thermostat.
Can I use sealant near the Oring when I connect the water cooler tube?
Thanks.
Why you didn't change the exhaust gasket? I will do the same operation to mine, and i ordered another exhaust gasket. It's a chance that i could use the old one?
Just a question dont you have to replace the gasket behind the timing chain water pump if you have oil in your coolent.
yes it is good practice to replace that gasket as it is often wrecked with oil in the coolant. known as the oil pump gasket
Do you need to wet the gaskets on the oil cooler with motor oil that goes onto the engine surface...like you would when changing an oil filter? What are you lubricating the O-rings with on the cooler pipe?
You can use a little oil on the oil seals and coolant o rings with coolant.
Hi, how much this would cost, have the same holden and oil cooler assembly is causing problem
Did you put a new oil cooler on? Or just clean it up and put it back on?
That was a new oil cooler as its the seal inside that age and leak. Thanks for the question.
Killa Watt Garage couldn’t you just replace the seals instead of replacing the whole housing?
this is a very excellant video!
Glad to help. Thanks for the comment.
This is an excellent tutorial. I did notice green coolant (Not Dexcool) I've heard that the Dexcool is harsher on the cooling system. Especially the hoses. Do you know if that is true?
I just heard the same thing today. Was told Dexcool is very acidic. I needed a rad flush today so instead they filled with another kind of coolant
Garbage GM isn't satisfied with just all of the regular cooling system failing, they're also going to trash this lol. GM should be DISSOLVED and execs imprisoned for life.
You have to wonder what was going on in the design rooms ........
great video mate! thanks ! mine is a 1.6L turbo and looks bit different to the one in your video. do u think the oil cooler is still at the same place under the exhaust manifold ? I cant see a oil filter near by though!
Yes, similar position.
Hi iam from South Africa
I have 2.2 chev captiva same problem
Want to know, is the oil cooler on the same side as the cruze like in the video
What started out as some sludge in the coolant reservoir is now a very oily substance.
Do you think it’s still the oil cooler ?
Oil in the engine is fine.
Yes very common for them to fail and produce oily coolant. Change or prepare the oil cooler. Thanks for the question
Killa Watt Garage what mileage did it fail at
90,000ish kilometres
Was easy to do with the help of your video
How long does it take to remove and install the exhaust manifold? What size is the bottom bolts that holds manifold in place?
I have done a few of these so I am getting quick, but allow yourself a couple of hours and you will get it done easily. The bolts securing the bottom of the manifold to a bracket on the block are a Torx head bolt. I don't remember the size?? Thanks for the questions.
I thought my head gasket leaking when found milky stuff in the radiatot reservoir....it is oil cooler unit couse the problem...but that oil cooler location is hard to tackle...
How can the water and oil in the cooler be put in the various compartments
how do you clean the resoivoir when you're done?
Lots of flushing. I just use water rather than coolant and drive the car 10-15 minutes and flush again and again. If really bad a dishwasher cleaning tablet in with the water and then a short drive, this does a really good job. Also take the reservoir off and rinse it. It takes awhile to get it clean. Also make sure the hoses are all still good.
After changing my thermostat housing, i get heat again but the radiator fan is still on full blast. I got yet another thermostat housing to replace the faulty one but found oil in my coolant this time. Also i noticed my oil light dings when I idle after driving for a little while. And cruise control quit after as well. I'm not sure what i could have done to cause this. Any ideas? I thought maybe i knocked something loose on the oil cooler. 2012 sonic 1.8L manual. Thanks, great video too by the way. Maybe I'll attempt to change the cooler gaskets as well.
always when replacing thermostat also replace the one $10 temp sensor on the left side of the radiator as it has one there and that was the one causing me to have fan on all the time.
Very good video clip.
Nice tutorial 👍🏻
Thank you! Cheers!
Excellent commentary
thanks glad it helped
Most people are going to not be able to just undo that O2 sensor .. a lot of cars the sensor is seized on it .. unless you have a butane torch you will struggle … so I had the 1.8 litre I left O2 sensor in place I just unplugged wire .. you remove the fan the electric fan is easy to remove two bolts up top .. then remove the front grill .. under there is the cross member 3 bolts on either side remove three bolts on air intake side and also one torx screw .. then once air intake pipes out .. two bolts to remove fan shroud .. then their is a plug under the car for fans .. then pulling out fan shroud one more wire just plugged into plastic .. manifold then slides out with no problem .. you would have been better off removing the fan shrouds .
no need to remove the sensor anyway.
Can a bad oil cooler cause coolant to go into the oil and get into the engine?
Loved the video. Just had our oil cooler replaced 4 days ago at our local Ex-Holden dealer. Since then it's leaking coolant from the smaller of the 2 pipes on the left. Checked the invoice (Over $1500) and only got charged for 2 O'rings for the outlet pipe. Do you believe they should have replaced 6 instead of only 2?
Sorry for the slow reply. If the o Rings are in good condition they can be reused but as they are cheap I would replace them, and it avoids issues later. Take it back and get them to fix the leak.
Hello I have a coolant leak. Can coolant leak from the oil cooler?
I have chevy cruze1.6L 2013 model, on the dash it complain of oil and the is having enough oil, is there anything wrong with the oil cooler, please help.
One simple question?
How do you get rid of all the oil that's still inside the coolant system after you've repaired or replaced the oil cooler/Oil cooler gasket?
Flush Flush and Flush. You can get additives to help. Dishwashing liquid is actually effective but can be super bubbly and needs lots of flushing to get it out of the system too.
What size socket was used to remove the heat shield bolts?
Thank you vary helpful :)
Thank u so much, found my issue. Oil in the radiator resivor and I was losing radiator fluid. Couldn't I just change the seals in the cooler? Or the whole thing should be replaced. Thank u a bunch 😌
Yes you can just change the cooler seals.
@@killawattgarage thank u 😁
Is it necessary to change the water pump as well when changing the oil cooler
no needed but they are generally cheap and if the oil cooler leak was bad I would recommend it
Hi how many hours labour and how much would this generally cost to replace?
Price of the part will vary. You also will need new coolant and it's a good time to do an oil change as well. These prices will vary country to country. The Oil Cooler replacement shouldn't be any more than 2 hrs of labour.
@@killawattgarage thanks for the reply. I'm taking my astra to my mechanic in England he says around 1.5/2 hours labour at £60 hour. I wonder how much the part will cost
You re the best thank u boss
Thank you for this video, it's just awsome.. I do the same ila my car, thank you man.. But i have an other problem, I noticed that in my Sonic when I accelerate I hear like a sound of coolant circulating inside the car. is it normal or is a part defective ?
It means that there is some air in the cooling system. Make sure that you can feel heat from the heater when the engine is warm. The sound is often more noticeable on a cold engine. Keep watching the coolant levels as it will settle/drop after some time. They are a hard system to purge the air from. In the factory they are vacuum filled and if you have access to this tool it is the best way. th-cam.com/video/5ZFe1GUzXGw/w-d-xo.html
thank you for your replay sir, yes I think that I have some air in the cooling circuit, I bleed the system 3 times and I changed the thermostat and the tank cap, and always the same... :/
, just one last little question, when the engine is hot and I open the tank cap, is it normal for the coolant to overflow?
give it a few heat and cooling cycles and it should be cleared up. If not there may be blocked hoses/heater core etc. Check the little hose that goes to the throttle body. Make sure it is clear and can flow.
@4:25 bet the exhaust loves that coolant lol!
It was perfectly portioned to catch the coolant LOL! It has a flex joint in there so I would have been able to drain most of it back out, but a good heads up to all.
