Brother fine video I just learned something new about bleeding the cooling system from my mistake. Winter time I had to let it bleed longer than in the summer time but an important lesson learned videos like yours save us money and teach us thank you for sharing
Thanks for the video and your honesty. I hate doing coolant flushes because it’s messy no matter how you do it, but, like you said, it has to be done. New subscriber!
8:21 Same thing happened with me, it's actually the heater core opening up a pushing the trapped air out. It took over 20 minutes for the heater core to finally open up, because it was really cold where I am. As soon as all that air boiled out, the heat finally kicked right on.
Good info in your video! My daughters 2013 JKU Wrangler has weak heat from center and driver side vents again (bought it used 3/2023 from a dealer) this was an issue two days after we bought it, so the dealer flushed and burped the cooling system and it seemed fine until the other day.. weak heat again and water fall sound coming from dash.. so I went to burp the system today, used the same process you did (minus the rev’s) it was burping well.. and then, I too got the volcano at about the 20min mark..it went from fine to holy crap and a matter of seconds so I shut it down.. I’ve never had this happen and like you been wrenching for 30-some years.. I glad it is something that happens and not something that just happened to me.. 😂 so the struggle continues.. new subscriber here too. 👍🏻
Did this fix your problem? I have a 2015 wrangler i just bought on halloween and found my heater is weak on the driver and the center. Hopefully this can be a cheap fix rather than a big heater core job
You need to reverse flush the heater core. My ‘16 I did but there was nothing, didn’t really need it. My ‘13 needs to be done every couple months. I finally washed it out with CLR and flushed it again. Seems good, so far. Find a vid, it’s super easy and it works.
i bought the vacuum type sold on amazon i think it was around $90 some dollars .you are suppose to use shop air pressure to cause your vacuum . i removed the air fitting and installed a 1/8x 1/4 Schrader fitting and will use my a/c repair vacuum pump inline with a empty freon jug that i installed another Schrader so i could pull thru the empty tank and not pull into the vacuum pump.had a 1988 cherokee that would give me fits with trapped air. had to park backwards on a hill and remove temp sensor and bleed the air from that point.
The fight is real! Some vehicles have cooling systems that are a real pain to bleed out, others can be very easy. I have the UView Airlift system that you talked about and while it does work quite nicely, I will say that it works best when you start with a completely empty cooling system. The emptier, the better. Like, drain the block empty. If you don't have the system empty enough, the tool will start sucking coolant out when it's trying to vacuum air out of the system and won't pull a strong vacuum. It's also handy for leak testing the system before you fill. You pull a vacuum, close off the valve and check back in 20 minutes. If it didn't hold the same vacuum level, you have a leak. It won't tell you where the leak is, just that there is a leak. To find the leak (with a completely empty system) pressurize the system to the rated capacity on the cap and spray suspect areas with soapy water. There are pneumatic cooling system pressure testers for this.
Great info. I love my coolant pressure tester. It has saved so much time over the years finding leaks. I have an old BG coolant flush machine out back that I used when I had my Commercial repair shop. It works just like a vacuum fill set up. The tank got cracked so I just use the old funnel.
I think I did a flush as part of another JK video but I can't remember. I have a lot of Jeep videos. Most are under Jeeps in the playlist but some are under Auto Repair. I know I did a flush on my brothers 2013 JK and forward and reverse flushed the heater core directly at the heater hoses.
I have a 2013 Jeep Wrangler Unlimited 3.6 liter. I’m having heater issues. The heater blows hot then cold. I checked the heater core lines they seem to be just warm after a long drive they should have been hot so I’m not sure what to check next. I did look at a video on replacing the Blender door Actuator but I’m not sure that’s it. I have noticed it’s running hotter according to my temperature gauge that normally runs in the middle but now the needle runs at about 3/4. Any suggestions? Thank you
The heater core is probably clogging up. I would do a coolant flush on the whole system and then take the heater hose lines loose and flush the heater core both directions. Make sure the water pump and thermostat are good. I have a few videos on the JK cooling system repairs. The heater cores are bad about clogging up and causing air pockets.
Cool video, thanks. How do you know if you have air in the lines. I tried flushing the core a few years back as my heat is room temp. Not a daily driver so I forget about it till winter. Both heater lines are hot. I may try this and see. What state are you in?
Hello, I got a 2021 Jeep GC, I recently changed the radiator and I’m not sure I bleed the system correctly or at all. Should I do what’s in this video? Pls help me out boss
My 2017 has a sloshing sound in the dash frequently and has recently started going to the third line on temp gauge before it drops to middle again all while fans are racing... thinking I may need to replace thermostat and burp/bleed the system.... This is my first "fiat" jeep
If you have some milage on it it wouldn't be a bad idea to put a thermostat and water pump on it. Look at the Doorman replacement parts. They have aluminum housing to replace the plastic parts for the 3.6.
Just bought a lovely jk unlimited. Radiator leaked . Replaced it burped the system. After driving a while heat gage rises above normal centre mark and back again to the centre mark. Fan runs high speed increases noise while driving when u decelerate it slows down like non stop. Clean Radiator core heater. Still doing the same .. car was running ok . I need assistance. I just Replaced Radiator. Please guys any info to sort will be Appreciated
You have not gotten all the air out of the system. You introduced a lot of air with the radiator replacement. You probably need several heat cycles to purge the system. I have found it draws in the most coolant after it has cooled down to ambient temperature. Generally not one burp and done. Been there done that.
@@joepandolfino4281 I have burped it several times.after that I opted to replace thermostat. Sender unit temp one. Waterpump.bled burped the system again. Drove it about 30 miles gauge fluctuating mid point to overheating . Fan blowing full speed. Checked circulation when fan on. Not blowing hot air like another one I had to compare it with. One side is hot on radiator other side cold air like its got a airgap or not burped properly. Did gas into coolant test to see if headgaskets not blown twice results was good no change in colour for the chemical. Swoped radiator fans from the one mentioned above. Still same . Fan working 100 % on the other jeep. Tried everything..removed thermostat drove it around 70 miles felt like it was getting until I was almost home gauge stood just above midpoint fans full speed again. I cannot understand why it would do the same symptoms with thermostat taken out of the housing. What should I do. My experience owning a jeep jk I have save so long for is becoming a nightmare gentleman. Please help. I m considering getting a mishimoto thermostat. But I don't understand it did the same without a thermostat in the housing. s
Continue to “burp” the system. I had the best luck running it then let it cool to ambient or over night. Repeat, repeat and repeat. It may take days but it is the trapped air. BTW, if you can park the JK with front end elevated on ramps or otherwise, that will help. Perseverance
What radiator cap funnel is that? Looks like it’s actually screwed on vs the funnel I’m just pushing in place that keeps coming loose as I’m trying to do this on my own. New to us 17 JKUR and has green in the radiator/motor and pink in the reservoir so plan to drain, flush and fill so looking at burping it now.
@@andrewdecavia7553 I don't remember the brand. I bought it on a tool truck a hundred years ago. It probably is a Lisle. They make good stuff. They have a few cap sizes that come with the kit. You just have to figure out the size you need for your application.
My jeep started overheating, replaced thermostat rad cap, pump burped the system a few times and still overheating. Had a big mess when coolant started boilling too.. have you been successful? Anything figure it out? Blown head gasket?
I would have to see it in person to be able to tell what's going on. Do you have heat coming out of the vents? Air pockets are the number one problem people have after a repair has been made. Does the heater core and radiator need flushed or replaced?
@@HotRodDaveFlush been done. I figured out a way to get bubbles out of the system, ride quite rouch, left and right, the coolant will go all over the place in there, problem solved! I'm in Canada a little to far my friend.. great video
If the radiator or the heater core has build up in them it can cause it to not bleed properly and do that. Try flushing the system and flush the heater core separately in both directions thoroughly. Then re bleed the system
Thank you for a detailed video. Isn't there a "bleeder valve" in the system to release the air? Have you used that before? If so, there must be a concern with it since you didn't mention it. I only ask because we used the heat in my Wife's 2012 JK this evening and it was only blowing hot when we were accelerating but the air cooled off significantly when we took the foot off of the pedal. So tomorrow I will be trying to address this issue. Thanks again!!
Yes but it is hard to get too it so I don't mess with it. It is also not at the top of the coolant system so I don't think it will work very well. I talk about it in the water pump and thermostat video on this Jeep
@@HotRodDave yep... i'm gonna have to do this tomorrow after replacing my thermostat.. i know theres one on the thermostat, but like you said, its about useless as tits on a boar hog... my old grand cherokee had a very convenient bleeding valve up top.... on top of that, why have a bleed valve down low on the thermostat, it needs to be high, thats where air gets caught
So we just run till volcano, shut down, fill and do it again until the volcano stops? I’ve also tried the vacuum and it doesn’t pull all the coolant in.
I try not to let it volcano but it happens sometimes. I would fill it and let it get hot and heat is coming from the vents. Shut it off and top it off over and over. They are bad about clogging the heater core and this slows the flow of coolant and makes it difficult to get the air out. You may need to flush the coolant system and back flush the heater core.
I have flushed the radiator and back flushed the heater core, but it just doesn’t run as cool as it used to. I’ve replaced the cap to the new OEM 17 lb cap as well. I have the funnel for the radiator and have tried to let air out. It will for about 3 cycles, then it’s a volcano so I shut it off. Also, it will fill the overflow tank, but it won’t pull back, so I’m thinking it’s because I have air in the system or a hole in the hose, but I think it’s air.
Ok I followed your suggestions and looks like I’m back in business. Looks like I got all the air out with no volcano. The system is running well. 222-226 fan comes on and cools to 215 with no volcano. Thanks man.
Cool! Thanks for watching and the feedback. Never hurts to let it cool off for a few hours after driving it real good and triple checking the level at the radiator cap.@@SniperFire45
@@HotRodDave well, I believe I may have bigger issues. It worked fine for a few days, and now it’s getting hot again. I think I have a blown head gasket.
Have a 2013 wrangler. Changed rad and thermostat. Rad was bad thermostat i broke plastic breather on thermostat. It has never ever over heated. Antifreeze keeps filling up overflow bottle. Keep putting it back in rad 2 days later overflow is full. Trying to get air out with that special funnel. Any ideas ??
The check engine light came on bought 3 weeks ago took it to AutoZone code said antifreeze issue can't remember the exact code number but it had to do with the coolant system. They asked me at AutoZone to check antifreeze level. That's the problem antifreeze goes into overflow bottle and won't go back In rad
@@HotRodDave so from day one I got my Jeep only on interstate at a higher rpm my Jeep temp would creep up to like 230’s 240 then go back down to regular temp, so yesterday I took it to a valvoline shop and they did a rad flush and fill and now it’s get a lot warmer and it’s only when driving in town now! It don’t over heat at idle which is good
@@HotRodDave but my Jeep never ever over heated. I’ve read that this engine runs more hot then normal it’s just how that are, but I wanted to try and see if I could get it to not get in the higher temps like it was from day one and now these fucks made it worse. The thermostat and housing is new also
I don't know on the town and country but the thermostat housing has a bleeder screw on the jeeps. They just are not easy to get to and look like a cheap plastic toy.
Whatever you call it the orange stuff is crap in my opinion If you don't get rid of the air pockets the orange stuff will gel My daughter Chevy had that junk when I started changing parts even the connector from the fill to the radiator was clogged with that orange goo only it was an orange cement. I don't know who worked on it before but I cleaned everything out flush that garbage down the drain metaphorically and replaced it with good old green stuff which is a lot cheaper and simply works better as it doesn't cause any damage even if there's air in the system but you still need to flush the system as possible to get air out
@@mannyjimenez1010 I could have lied and not shown what can happen but I don't like fake bs. It can be a messy job. I hope you make a video showing me what I did wrong since you are the pro. Let me ask you a question. Why did you watch the video in the first place if you are such a top notch mechanic ?
@HotRodDave it just came out on you tube,and I thought what a crappie video. I am not a pro or clame to be Mr .when I used to work as an auto technician. 👎 peace out.

Mixing OAT with HOAT coolant will gel and cause extensive clogging of your system. Always use the correct type for your Jeep model.

You can squeeze and let go upper radiation hose multiple times to burp system of air. Combination with your way should work great

That is a good point. Sometimes lifting the front up can help get the trapped air out.

Sometimes it will overheat and push out coolant. Sometimes it will not have good heat or no heat at all. I'm in north Georgia
Does this replace the process of bleeding air at the thermostat housing?
This is how I do it. The bleeder at the thermostat is too hard to get to on a Wrangler

So I guess as long as your heater is blowing hot air you got it purged and all the air is bubbles is out of the radiator correct 🤔
Yes if you have good heat you probably have the air out
When you pulled jeep out to rinse i saw upper radiator hose completely collapsed
Yeah they will do that sometimes until you get all the air out
I thought the recovery system was supposed to burp the system automatically?
What recovery system is that?
Coolant? What else?

The recovery is lower than the heater core tho .
Still trapped air
Im fighting my 2014 town and country right now
I don't know on the town and country but the thermostat housing has a bleeder screw on the jeeps. They just are not easy to get to and look like a cheap plastic toy.
Whatever you call it the orange stuff is crap in my opinion
If you don't get rid of the air pockets the orange stuff will gel
My daughter Chevy had that junk when I started changing parts even the connector from the fill to the radiator was clogged with that orange goo only it was an orange cement.
I don't know who worked on it before but I cleaned everything out flush that garbage down the drain metaphorically and replaced it with good old green stuff which is a lot cheaper and simply works better as it doesn't cause any damage even if there's air in the system but you still need to flush the system as possible to get air out
Yeah the dexcool gm coolant had alot of problems especially if you mix it with green. I have seen it turn brown and get thick
Never cross mix coolants
Especially the hoat & oat
Dude, do you evan know what you're doing ? You were not a very good tech .wher you?
What did you not like Sir ?
@HotRodDave Everything you did was just wrong. P/S and you made a mess of things.
@@mannyjimenez1010 I could have lied and not shown what can happen but I don't like fake bs. It can be a messy job. I hope you make a video showing me what I did wrong since you are the pro. Let me ask you a question. Why did you watch the video in the first place if you are such a top notch mechanic ?
@HotRodDave it just came out on you tube,and I thought what a crappie video. I am not a pro or clame to be Mr .when I used to work as an auto technician. 👎 peace out.
