Gracias amigo 🫡👍🏾👍🏾👍🏾👍🏾
good job
This video has a grate that supports me to drain vw tiguan and replace after the oil cooler. Good job 😍👨🔧
I have few problems to clear about this repair. How can I contact you team.
Hi, the G13 is not the newest anymore and was also replaced by G12evo. The G13 is clogging the coolers over time... The G12evo is compatible like G13 to the old ones.
And also the stuff he used isn't g13 anyways lol
You‘re right. If you renew your coolant fluid, change to g12 evo. And another important thing you must do:
If you have a g13 coolant reservoir, remove the silicat bag from the reservoir. This is the cause for clogging…
👍
Thanks for the video my man. Was wondering if there was NO drainplug and you answered that!
I've got a leak on a weird hose that goes around thge back left of the engine that looks like it will be near impossible to fix.
Ever tackle that one?
I haven't worked on these cars too often so I can't say. Only done a few things here and there, but that's it. But what I do know is the water pump and the auxiliary plastic pump are common to leak on these models.
@@moosemobileautorepair Yes they are and I've replaced both on this POS.
This is my daughters car and she "loves it"
Otherwise I woulda towed it to the junk yard years ago.
Lol 😆. The 2.0 liter TSI engines are known to fail such as the timing chain and stuff. I've done rear coil springs and a few things on these cars. I've also seen the PCV valve failing and causing a rear main seal leak. I don't work on them too often, but yeah I don't recommend these cars because of parts and labour being expensive. They're fun cars to drive, but not worth it unless you have the money.
So can you mix G12, G12+ and G13...for example if you want to top up not completely replace?
Hey man! This is awesome.
Btw. My sister's 2018 Tiguan just got the thermostat and housing assembly replaced by a "Mechanic" and it is still overheating.
The fans do actually turn on.
I will try this procedure.
Do you recommend anything else?
I was thinking about using a vaccum pump with vehicle off..
Thank you soo much!
Try to follow the procedures in this video to properly bleed the system and see if it solves the problem. If not, I would have a look at the secondary/auxiliary water pump to see if it's working as that helps to push and circulate coolant in the system.
I would also check to see if the primary water pump is working properly and if it is leaking and if the ECT sensor is working as well. It's hard to diagnose without looking at the vehicle, but those are some things to check.
Also, using the wrong coolant on these vehicles may cause gelling and clog up passageways in the cooling system so that can cause problems too.
Keep an eye on the reservoir to see if the fluid is circulating in the system when you are performing the bleeding procedures. If not, I would suspect one or both of the water pumps are not working properly.
@@moosemobileautorepair Oooohh woooowww!! Thanks a lot man!!! You are freaking amazing.
Will do 🫡
Happy holidays btw!
Great video, really helpful! Is there any way you could share the service manual documentation?
Really thanks for your great video. A question, why you didn't draing from one of the lower big hoses? for example the one you show at 4:29
Thanks. I think because it may have been difficult to access and those ones had a special type style of clamp that locks and so I decided not to touch it and leave it alone. You can remove it if you want whichever is easier. The one I removed drained a little bit from the block as well as from the radiator through the hose I drained from.
It was a Friday that day so I didn't want to open any can of worms so I picked what's easiest to remove and drained the coolant from there.
You did absolutely great job already, i have a Passat B8 2016 with contaminated coolant because of this silicate nightmare ended by clogged heater core. It was replaced by VW for a 1200 bucks here in France . Week after i noticed there are still brown particles in the expansion reservoir and the coolant is orange-brown. So i decided to flush the coolant by myself. So far i learned from your video that it is impossible to drain the whole coolant from these cars with the auxiliary heater. I believe using the flush additives are not possible in this cars while I can't drain it for a same reason. I want to go with your procedure but i want also to put the garden hose in the reservoir and try to push dirt as much as possible out at least from the radiator circuit while it is impossible to do this for block circuit. Then try to use the compressed air to drain the water too and fill with the G12 evo instead of G13 also replace the reservoire.Also I think but I’m still not sure if worth it, what do you think?
That's nuts. That's quite some story. It's worth a try to flush everything out or do multiple drain and fills too if needed.
If you say brown colour, that could mean that there could be a leaky head gasket because usually oil and coolant getting mixed together would turn like a milky brown colour. Let me know otherwise, but yes it's worth to try to flush it out if you're having those problems.
How does the vehicle run and drive otherwise?
@@moosemobileautorepair the car is super fine, it’s on 40k miles only after 7 years. This was very first surprise. The coolant is not milky brown, it’s transparent looks like light tea with a very small brown particles inside ( very very small like a dust) , thanks again bro, god bless you and your business
Thanks. Try flushing it out how you stated and see if it helps and that should help to get the brown stuff out. Most likely because of incompatible coolants mixing up together like you stated earlier about the silicates.
Hey man.. thanks for making this video.. im about to do a flush on my vw tiguan.. i have a question.. as you know, when you drain the coolant from that hose( minute 8), that's not all the coolant in the system , there's some coolant left in engine block .. how can you drain that safely? start the engine with hose unattached?
That's right. It is not all of the coolant in the system, you probably get about half or 2/3 out. But if you do periodic maintenance at the right intervals then you should be OK with this service. You don't want to run the engine while you have all of the coolant drained out from the radiator/system because that will run the water pump dry and damage the seals, etc. and cause premature failure. If you want to remove all of the coolant you can attach a garden hose from either side and flush it out with water through the hose and block and you will be able to get all of the coolant out then. On some vehicles they have drain valves located somewhere on the block, but I typically don't touch them as you could open a can of worms and cause more harm than good. I typically just do a drain and fill at regular intervals and you should be OK with that. You can also do the service twice if you're really worried about getting everything out and getting it clean otherwise you could just flush it out with a garden hose or by using a coolant exchanger machine that shops typically have.
@@moosemobileautorepair thanks for letting me know, the thing is.. i added some radiator cleaner to the coolant so i can flush the whole system, but the original problem is, no hot air comes out of the vents when i have on heating , after diagnosing the issue turns out the heater core is clogged .. so i want to unclog the heater core and flush the whole system since it has never been replaced before. I like the water hose idea but how can i get that water out if i want to add 50/50 coolant?.. can I use air to push the old coolant out?
You need water to push coolant out. You can safely use tap water from the garden hose and maybe use a special adapter if available or something so it doesn't spray everywhere. Using approved cleaners should be OK as long as it gets drained out after the service is done. I would try to bleed the cooling system out properly first before condemning the heater core. In most cases no heat through the vents is most likely because the cooling system has not been bled properly. Very rarely it will be the heater core, but it is still possible. You may want to check the thermostat as well to see if it is opening and if the cooling fans are coming on. It would be a good idea to check for any TSBs as well (Technical Service Bulletin).
@@moosemobileautorepair so if I use the garden hose to. flush it out, then i add new coolant, once that 50/50 gets mixed up with water in engine block, its not 50/50 anymore, its less than that .. right?. plus tap water has minerals so its like that calcium will build up inside the system, probably safer to use distilled water. The thermostat and fan are working properly.. what is a TBS?.. yeah so my biggest concern is how to get the garden hose water out?
For the garden hose you can insert it into one of the radiator hoses to flush the block out. There is a hose gun adapter by Lisle which you can get for cheap off Amazon. It's OK to use tap water for flushing it out only. But after you're done flushing you use either the pre-mixed coolant or concentrated coolant with distilled water to get a 50/50 mixture.
A Technical Service Bulletin is information sent from a manufacturer to service centers that describes a specific problem with a particular vehicle. It typically also includes an explanation as to how to correct the issue in terms of repair, software reflash, or modification of the automobile.

I have a tiguan 2.0 tsi from 2011 . Hoe much liters i need ? I saw a video saying 10 liter ? Its correct ?
That is if you are doing a full flush considering that you have the coolant exchanger/flush equipment/machine. The full capacity is 11 liters total for a full system flush.
@@moosemobileautorepair Thanks for help. I dont think need a full flush.
1 gallon jug of concentrated coolant should be enough and distilled water or 1 jug of 50/50 pre-mixed is also OK. Just have some tiny bit extra just in case. A flush is not really necessary on vehicles unless there is a problem or neglected maintenance. A regular drain and fill at regular service intervals works fine.
@@moosemobileautorepair I just bought the car There are no problems, the water just doesn't look that clean. I think if I renew a few liters it will look good again
Hello I had a problem! I went to a garage, changed coolant to a 1.2 tsi. The problem was that the engine overheated. On a hose no coolant alwas getting to the water pump, and the thermostat did not open. After lots off overheating, taking hoses out to bleed air, the temperature stays at 90 degress, but the fans do not turn on. Only on A/C. Could be that they put the heat on when they turn on the engine after changing the coolant? Thank you!
Most likely the cooling system was not bled properly. Unless there is a separate problem with the cooling fans not coming on then there would be some electrical issue that would need to be diagnosed. The cooling fans should come on and off intermittently if you are idling for some time and only come on at low driving speeds. When you are bleeding the cooling system you need to make sure that the coolant is being topped off for each time the level drops in the expansion tank/reservoir tank. I would suspect that the thermostat may be bad and may be stuck in the closed position causing the engine to overheat. I would check that as well.
Also, I would double check the correct bleeding procedures for that engine because each engine will have their own unique bleeding procedures and so it may not be exactly the same as shown in my video here. This video is for the 2.0 TSI engine and so I'm not sure if the 1.2 TSI is the same procedure although it may be similar.
How much time u had to wait for the cooling fan to turn on?
I can't remember exactly, but roughly 30 to 45 minutes.
Hey bro my Tiguan is leaking coolant but I can't see where its coming from..... would appreciate some help very much..
On these models the water pump is common to leak which would be on the driver's side area on top. They are driven by the camshaft. Leaks would start from top and work their way down. Another common leak would be from the tee connections where the plastic is when they get old and brittle. Start with those and see if there is anything. You may need to lift the vehicle up in the air and remove the service cover to see what is going on. Alternatively, you can pressure test the system with a pressure tester kit as well.
Hi,❤ I have Golf 5 2.0 tdi 2005 its be problem to change my coolant G12 for G12 Evo?😊
Can I do this to my 2016 VW Tiguan ?
Yes, it should be the same exact procedure with the same engine.
Is it safe to mix G12 & G13 coolants?
It should be OK to mix those two, but preferably, I would use the same type of coolant that your vehicle takes.
Can I ask why they want the heater to be OFF? Surely it's better to have it on going through the heater core?
So that the engine can warm up faster. It's only for 3 minutes then you turn the heater on after that. Having the heater on helps to cool the cooling system down and engine down a bit.
An additional step is to run the car with distilled water in the system multiple times to flush all the coolant in the heater core and block them drain and repeat before adding the final new coolant
Respect to you my friend you dont give care what anyone think or says not everyone can say th3 same 🫡
