Thank you for posting this. Your still helping people 5 years later

Watching your video helped me diagnose my heater issue. Very useful. Thanx for sharing. I am the sole breadwinner of a family of 6, so this will save me alot of money.

Something else to consider if the bubbles never seem to go completely away. A small headgasket leak between the water jacket and the sealing surface around the piston is allowing compression into the coolant system and youll be burping air the rest of your life.

I know this is an old video, but thanks for putting it out there. I'm contemplating changing the heater hose parts that are plastic to aluminum ones I've found online. The plastic tends to get brittle over time. I've never had to burp my Xterra and now I know what to look for.

If you have a mechanical fan run the engine until the top hose and bottom hose are hot (tells you that the thermostat is open) also you can raise the front of the vehicle by parking up on a kerb or a hill, as air rises it will come out eventually but it can take a while. by the way good video

just got done replacing the radiator, tstat, water pump and a bunch of rusted out water pipes and burping the system was easily the worst part of the job. Thanks for this vid.

dude!! thank you so much for this video!! this helped so much! they used the machine on mine as well at jiffy lube I'll never let them change my fluid ever again

That's awesome man...getting into winter here in Canada. This got me my heat back. Thanks man

You want something done the right way, you do it your self lol

If you have air after they did a vacuumed coolant replacement, they either didn't seal it right, didn't use the machine correctly, or the machine just didn't work with your car for one reason or another. This did give me an idea for an overheating car I'm stumped on, so thanks for that.

This is good information, appreciate your time and efforts. Thanks...

Still a helpful video! The only additional advice I've heard was to elevate the front end of the car to help the air bubbles float up through hoses.

Performed this procedure yesterday. Apparently there was enough air in the system to prevent the heater from working at low rpm. It works fine now.

Just tried this on my wife's FX35, it worked! Thanks for making the video!

I work at the dealership as a mechanic most of the people I work with have no clue what are they doing.

Amen! Dealers make excuses when they don’t know what they are doing!! And still want to break your checking account!

Whilst no harm is done in undertaking this exercise if you simply ensure the level of coolant in the expansion tank is at the correct (i.e. between LOW & HIGH mark) when cold and you start the car up and run it at fast idle with passenger cabin heater thermostat set to maximum and AC (if vehicle is fitted with one) turned on until the engine temperature reaches the correct high level. You can even go for a good long drive as well. Stop the engine, note the level of coolant in the expansion tank and if it is below the MIN mark top it up to the correct level and let the whole system cool overnight and recheck the coolant level in the expansion tank and top up if necessary. This is the correct procedure to purge air out of the cooling system. Unless there is a fault condition such as coolant leak you should never have to take off the radiator cap to top up the coolant or purge air out of the car's cooling system. The thermal expansion tank, by design, is always situated slightly below the height of the radiator cap. good video thanks. You will find that in the latest generation of petrol driven cars there is no air bleed valve in the cooling system either.

Thank You Sir my Xterra pro 4X tortured me with this identical problem. I’ve been squeezing the wrong hose!

Aww man thanks...You just saved me a hell of alot of time and money.

Thanks for taking the time to teach us all!🙋

Just had my 2011 Frontier in for coolant service. Dealer stated 100,000 miles or seven years. $139. On way home blowing ice cold air at idle or low speed. Under acceleration or around 2,000 rpm it blows hot air. Took it right back and they supposedly checked it and system was functioning properly. Freakin 20 degrees out and can't use defroster as air coming out is ice cold. They wanted to change thermostat, but I felt it didn't need it as the heat was fine before service. I saw this video and tried your procedure. It took me around 45 minutes but got the air out. I loosened the pressure cap on the overflow tank after 30 minutes for a minute and a lot of air bubbled in the funnel ? Put cap back on bottle and ran motor about 15 minutes more and heat was coming out of the dash great as it always has. Thanks for the video, your a life saver.

Do it “yo damn self!” LOVE IT, and thank you for this. Can’t wait to try it!

Nice job, great info to know. I am having the same problem, I will try this today!! Didn't even ask the dealer about it, I will just fix it myself.

Thanks for the info--Had front end damage and they replaced radiator--I did what you showed and now I have hot air. Thanks again

Just try this method and it actually works awesome thanks

Thanks a lot for the video. My Citroen Berlingo has had bad heating for a while now, freezing cold air when idling. I shall give this method a try tomorrow and hope it cures the problem!

I had nearly the same thing happen from SEARS! (No wonder they’re gone now!) Coolant Change Special, took neighbor’s kids to see movie near Auto Center while being done. Car got hot on drive home. Had to get kids back so couldn’t take back to Sears. Had to fight/argue on phone but they reimbursed a new coolant tank, hose & several gallons of coolant. They used green when Res cap says only ORANGE (OAT-Aluminum engine.) But went to flush myself & initially green then orange so NEVER FLUSHED! (Prob drained plastic tank only!) So I flushed TWICE! Then refilled. Before that changed recovery bottle & attached hose! (They broke nozzle from coolant bottle inside hose & figured ‘Who’s gonna know?!’) Better to watch stuff like this & learn to do yourself!

Hey brother. Good video. Thank you for posting this, saves me time and money!

Thank you man so much for this video I was fixing to sell my truck had it in the shop too many times for the same exact reason kept overheating and then I saw your video. My truck was overheating Within 20 seconds of driving it down the road and the dealership could not figure out what it was but they kept charging me to fix it. I knew that the temperature is not going to rise that fast, the temperature gauge would shoot up crazy fast all the way maxed out to the hot, I would pull over immediately and turn off the truck. It was building a lot of air pressure up, so I would do what most people would not do I took the radiator cap off and it exploded all over me and the truck with cold antifreeze LOL. The radiator was cold and the hose was cold but it was hard as a rock, a guy looked at me cross-eyed when he was walking by he thought I got scalded by the antifreeze but it wasn't even hot I told him he just laughed like damn!! Hahaha so thanks a lot man again you're awesome for sharing that video

With bigger Nissan trucks, sometimes it takes few days of driving and then repeat the bleeding procedure. Specially if you have a heating system for the rear seats.

Thanx for the video! Congratulations on a job well done and showing that dealers are not perfect either!

Good video!!! Thanks. Taught me something i had forgotten.

That's beautiful. My neighbor have an issue with his car and I think someone drains some coolant to change the alternator and now I blowing crazy whit smoke. I suspect overheating issues. I'm going over to start squeezing every hose I find. Thanks for the video. Some cars have a valve just for that but this should work just fine

I had the no heat at idle problem on my 2010 Xterra once after the dealership replaced a heater hose fitting that they broke. When I noticed the no heat issue I called the service advisor and took it right back to them. They ran it just like you did with the funnel and had it good to go within a half hour. While I was annoyed that I had a problem and had to go back to the dealer, I can't complain about the service at my dealership. (Now that I know the no heat on idle is due to trapped air, next time I will probably just fix it myself. I just wasn't sure what was up and figured it was something they did so they should fix it...) The 1st Generation Xterra's with the 3.3L engine (VG33E) had an air bleed screw on the top of the intake manifold. I wonder why the 4.0 (VQ40) doesn't have one? It seems like that would help with this problem since it would bleed the air out as you fill the system. I never had any problems with trapped air on my '01.

Try increasing the Engine speed to 1500 rpm for brief periods and make sure the cooling fans come on twice.

Thank you! Last night, Travis and I put in the new heater core.

I've done repairs on many different vehicles and models. I have found nissans for some reason are difficult to bleed the air out of the coolant system.

Apart from Scotty Kilmer, I have yet to see a genuine mechanic that actually knows what he is doing. Lets face it, there are too many different types of cars out there for 1 mechanic to know everything about them. Even specialist dealerships don't know how to fix their own cars. Most DIY mechanics know more about cars than your so called professional mechanics, and that's a fact!

Wow! I was so doubtful that it is going to work but decided to give it a try and what do you know? It works! Thanks for saving my winter 🙏🏻

Right on man, my 07 is having the no heat issue. Was 26 this morning, had to rev the engine to get heat. Changing the serpentine belt and a pulley tomorrow, lol adding burping to the list, hell I'll probably just flush it out.

Thanks bro good video helped me out and it's cold this winter

If you don't do this, air inside the system will damage any component, including heater core and if you don't know about the cost about that, make search $$$ a lot!

good job. i have the same truck, and mine is a 2014 frontier, with the same problem. it's going into the dealer tomorrow, and hopefully they will fix it. they said i should try driving with the expansion tank cap open for 15 minutes, and i did that a few times, and now it's worse because i don't have heat every time i start the truck, when it was happening about half the time. it's not acceptable for nissan to let this problem go on for years, and from what i've read here, it seems to happen to all nissan models. we should all contact them to let them know how disappointed we are for this ongoing problem, and that we won't be buying anymore nissans if this is how their quality control is going to conduct their business.

Your coolant has the same symptom as I have after drinking too much Pepsi ;)

Thank you! This Fixed my pathfinder!!!

What did you do with all that antifreeze left in the funnel. Did you allow the coolant to cool down and be reabsorbed into the system or did you just siphon it out of the funnel

Hey thank you for this video. I hate issues and it always seems if you want it done right, better do it your self.

This video saved my hide. Thanks

Some funnels won't fit in the radiator cap opening. If the funnel is too small, wrap electrical tape or duct tape around the funnel neck to increase its diameter so it fits snug and won't leak when the engine is running.

thanks man I got this problem right now I"m going to give this a try thanks again Bother. Which part of the Tr-State you from me I'm from Queens.

Sometimes I'll go ahead & up the idle a little, just as the t-stat pops open, to push that coolant a little harder through the system. THAT'LL usually get the last of those big voids (bubbles) out of the coolant circuit (hoses) around the heater core.

I'm having that same problem right now I need to try this.

I'm trying this in the morning! My heat is blowing cold. I have a 2012 Xterra. I added coolant today, but it's still cold. I'll try squeezing the hose thing. I can hear gurgling sounds when I turn my truck off so it sounds like coolant is stuck somewhere.. or it has air bubbles.

Thanks for the video man!! Helped save me some money. That was way easy

The bubbles still there at the end of the video. I didn't see you solved the problem??? only when there's no bubble then you can tell the air is out!

I feel like i am on hallucinogens looking at your video your camera is distorting lol.

Nice work. I don't take any of my vehicles to stealerships unless there's a recall on a specific issue that only they can service.

Great vid, very helpful. Thank you!

Thanks for the vid man! I have to try this. I gots to get me some heat!!!!

Good job...followed to the T. Worked out. Thanks!

Great video ! It took care of my problem...👍🏻👍🏻

Rad'E'ator. :D

No heat, plenty of air, hot hoses to core, but no heat. Maybe , like you said, "too much air in water hoses! 😃

Thank you for your video it really help me

do this. then do it again the next day and it wont happen again idk why but it kept happening to alot of people and doing it multiple times works for some reason. can also be the housing near the thermostat blocking the flow of water causing the air to sit in the hose.

thanks for the video! I need to do this after replacing my radiator, and I'm getting no heat.

Thanks for the video. My Pathfinder is blowing cool air at idle but blows hot air over 1200 rpm. I will try this procedure. It makes sense to me.

thanks for helping for posting this help me a lot ...!

Thanks for the video, going to give it a go this weekend

Ok start off by drilling a 1/8 hole in thermostat slightly inboard off the gasket to relieve steam then take your top radiator hose off the radiator twist it up and fill your engine up to meet radiator fluid at the bottom hose filling both sides, go slowly before you put heat in the system, heat causes steam, you can massage top and bottom hoses to burp it ,try it with cap on and off, good luck from tassie

Why do people insist on turning the heater fan on? You open the heat switch and water flows through the entire cooling system. Turning the fan on doesn't do anything except make your car hot inside

on the nissans infinitis you gotta get the front of the car in air as high as you can with with spill free funnel temp setting to full hot holding at 2 to 3000 rpm untill heat as good at idle yes vacuum fill method is best way on most cars especially bmws ..but nissans this method usually works and maks sure you over flow bottle level is kept over the max

That Worked! All I had to do was put some fluid in it, and burp it... Now She is Happy!

Worked perfectly! Thanks my man!

Common malady of the Frontier, which I have... and I see by your dash that you have as well!

Same thing happened with my old explorer, except there was enough air to cause an overheating issue also. took forever to get it back to the dealer. This condition is know as Vapor lock.

thanks for an easy explanation sir...

so what do i do with the antifreeze after all th air comes out? does it just flow down?

Wow just want said thank you I found your video I do the same things as u do and is blow pretty good now snice is -35 here in canada

Thanks for sharing.

Your video saved my life

Great video, thanks for sharing!

...same thing just happened to me bro..have to burp my baby myself...Dealers suck and so do most shops..jus a fact of life..great vid!

Fan should've been on lowest setting. The more air moving through the heater core makes it act more like the radiator.

Yours looks good. Mine is full of bubbles

Good information Thanks

Very good job thank you, I can't help but to say you have to clean that engine cover my msn lol

Thanks brother

I took my xterra to an independent mechanic to have the radiator and thermostat replaced. First he didn’t seal the thermostat so it leaked all kinds of coolant. Took it back to him to fix it. He sealed it with rtv sealer. He said he wouldn’t mess with it anymore. So it’s been about a week and the temp starts to rise after about 5- 10 minutes of Idling. So after doing research most likely there is air in the system so I’m gonna try to do this method

You can have a blown head gasket without getting coolant in the oil...it can go out the exhaust valves and out the tail pipe.

The overflow is actually the pressure side wouldn’t that cause air to enter the system.

What you do when time to remove funnel and all that coolant is in there??

Great video man, thanks!

Amazing stuff. Thank you

There's more to this than he described. I don't think the funnel is necessary. Just leave the cap a little loose and hope the airlock bubbles out. People open their caps all the time and I even replaced the radiator inlet hose and had heat soon after replacing half gallon of coolant. The scary part is having this problem after doing a cleaning flush :-( Wondering if the cleaning plugged the heating system. Edit: Maybe some cars have the heater core tube connections higher compared to the radiator overflow. I suggest find some hills to drive up and down to help move the air out of the heater core.

Thanks, this was the only thing that worked on my G35. Rig up something that will hold the gas pedal around 1.5-2k rpm and it should speed the process up significantly. Lotsa bubbles!

Thanks. You know at $39 they just wanted you to bring the car back so they could charge you to fix something else.

I brought my frontier into every Nissan shop in town with no gear on idol. They always said it was fine. Got really pissed yelled some. Did this a while ago and it worked. Now I do it year about.

'So much for listening to those jokers' lol. Same story every day.

do you need a special funnel or any old one? do you take the cap off put the funnel in and fill it with coolant then turn the vehicle on?
