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 flush out my own coolant system and heater core system, you know your system will last you for five years after your DIY lot of work but you will be well rewarded. If your heater core doesn't leak just flush it, the incompetent thieves are real out here.
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
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
@@mid-west_man You do pour water in coolant if it's not prediluted. It's the cheaper way instead of buying 50/50 coolant, which is half water. They get that stuff in bulk. Not the newest way to do it, but they weren't doing wrong by you. Now, not burping the air completely out would be an error on their part.
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.
Hola cómo estás muchas gracias por el video una pregunta un consejo más bien se me barrió el tapón de plástico de drenaje del anticongelante de un Nissan Frontier 2018 se le hizo el tapón tornillo y ahora está drenando el antifreeze pero bueno si estás remover el tornillo de plástico y está sumido para adentro tienes tips para saber cómo removerlo muchas gracias espero su respuesta
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.
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.
That method does work but it'll take days. Some engines are sensitive to even slight overheating (like my 4.7 Powertech Dodge engine). Driving around with excess air can keep temps up higher than usual and cause all kinds of issues like valve stem seals messing up, head gaskets, etc. This method ensures that anytime air comes out, it's replaced by coolant and the temp stays at the correct range. And you only have to do it once or twice and not risk destroying your motor on the road.
Offroadtaco most places are like that... atleast you're honest about the people your work with. I've seen it with my own eyes, so called mechanics working on vehicles and have no clue what they're doing and me being self taught, I cringe and i dont even have my mechanic licence but know vehicles inside and out
@@tousshong9438 on a closed system there is no fill cap on the radiator it's just the reservoir and if you put that on the reservoir it won't get the air out of the system you either have to vacuum the line and then fill it or use a bleeder valve
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!
I think the “Chrisfix” UA-cam channel is pretty good and he knows his stuff. BUT MOST IMPORTANTLY ..... he’s straight up honest when there’s something HE DOESNT KNOW or completely understand. That’s the most important thing with anyone in any occupation… Be honest and upfront about what you DONT KNOW and decline jobs you aren’t comfortable with. That’s one of the only ways to keep learning
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.
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!
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.
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
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
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!
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.
My 06 Frontier has had this problem for the last year , about to start looking into it to finally fix it , at long lights I gotta give my truck some gas to get heat
same problem with my 2008 Infiniti QX56 (a.k.a. fully loaded souped up nissan Armada) for about almost a year now. No heat unless I drive it around for about 5-10 mins. Imma try this method this weekend and see what happens!
Tac0 panda; the dealer had to burp/purge the cooling system of the air trapped. six years later it’s doing it again and they want $140 just to bleed the system and it’s just standing there waiting for the air to come out.
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
I saw a guy on youtube with the radiator cap open like this and the engine running. So I turned my engine off and thought it would be fine to pop the radiator cap off. Nope. Thought I was dead for a second. I peeled off my hat, my glasses and my work short in .5 seconds as I backed away from the car lmao. I seem to have to bleed my civic once every 3-600 miles. Not sure why yet. Just sent it in for a head gasket they replaced the radiator and thermostat saying it was full of rock hard stuff. Like rock candy. From mixing coolants apparently.
You need to bleed the air out of your cooling system otherwise the temp will get super hot at idle. You can buy a radiator bleeding system on Amazon for less than $20. You need to park your car an upward angle to do this procedure. Good Luck!!
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!
I got to try this. I put my heat up to 90 but the cold air flows threw. Then while I drive for like 10 min a bit of warm air comes threw hope this works.
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.
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.
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
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.
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.
Ningishzidda Shar I have an infiniti (owned by Nissan) and ever since having my water pump fixed, I’ve had to do this every couple months. Not sure why it continues to happen
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.
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
You're speaking from experience? Specifically with the Nissan pathfinder/xtera/frontier? that seems to make sense, to keep that expansion tank on max... because there's a hose that leads right to there from the heater hose assembly/junction next to the core ports.
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 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.
@@mississippiafterdark you need to buy a funnel they're cheap they have the right nozzle to fit in to radiator as mine has a slant right on the inside of the rad. As for the rest im not %100. Pretty sure you fill it and start it and a bunch is gonna come pouring out so it's good to have a nice big funnel or something you can tip it into when it overflows the funnel Because radiator fluid expands heats up. Then once you do everything it tells you to do and get the bubbles out you need to I believe make sure it's full again after its cool down. Make sure you rev your engine up to 2rpm for a bit i forgot to do that step and i failed my 1st attempt Update : second attempt is a Success! this time for some reason it didn't overflow on me in my small funnel. I got lots of heat now at idle. Thanks to the maker of the video.
So i have a question about yout video. I notice that your oil pressure gauge was reading low. The oil pressure is shows good whne the engine is cold at idle and when it warms up the the oil pressure on the guage starts to drop at idle. when the engine is at 3 to4 the oil pressure shows good on the gauge. The reason i ask is that my 2005 is doing the samething . it that a normal thing with pathfinders?
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.
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.
Hello mate.i got an mercedes benz a class a 170..2005...mine blow air but dont come warm air..what i can do?all works before to i go in holliday,when i comeback give low warm air,but now it stop give warn air inside the cabin.
How long did it bubble for? I have a 2017 frontier and from what I read in a frontier forum our trucks will keep bubbling due to the pressurized reservoir tank. What was your experience? Thanks brotha!
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
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 need to bleed the air out of your cooling system otherwise the temp will get super hot at idle. You can buy a radiator bleeding system on Amazon for less than $20. You need to park your car an upward angle to do this procedure. Good Luck!!
My defrost want defrost the windshield if I start my frontier but soon as I get in it and start to drive it starts blowing the warm air. Will doing this fix my problem?
@@obe1canobe146 that exactly how you do it you making you a plug out of a screwdriver with a rag and poke it down in the funnel hole and pull it out quickly.
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.
Hi. I just bought a 2018 Nissan Frontier. My heater will blow warm and then cool. I took it in and they told me that there is a automatic sensor in the truck and it will regulate it self...crazy thing is I don’t have it on the auto system...I think they are lying to me cause it’s easier to send me away then fix my truck...did you have something similar? Blowing warm and then all of a sudden cool air?
See that's exactly what I'm talkin about I have this PT cruiser it overheats but they replaced everything and I don't think they got all the air out of the system and they keep saying it's a head gasket but I don't think so. like your video at idle I don't have no heat but when I rev the engine I get heat I'm wondering could that be the issue I guess I'll have to do it my damn self 😤😒😉👊💪 great video it gives me Faith hopefully it's not the head gasket 🤔😨😢😉👊💪💯
I did this today and It worked temporarily but after removing the funnel and putting cap back on I’m still having the same issue. Are we supposed to fill the funnel with antifreeze before doing this? Also my funnel wasn’t tight and I kept squeezing the hose after pressing the gas pedal. Repeated doing this for an hour and still no luck 😢
I put coolant in last night after work (1998 dodge neon) drove home woke up this morning my ac and heat both don’t work I live in Alberta I couldn’t even drive this morning it was to cold and couldn’t see is there bubbles in my think I will try the steps in video

Both Kerb and Curb is correct. One is a UK/Commonwealth spelling and one is a US spelling.
Same can be said about reinstalling something. In the UK they use the term refit. Replacement of parts they call it renewal.

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
I saw a guy on youtube with the radiator cap open like this and the engine running. So I turned my engine off and thought it would be fine to pop the radiator cap off. Nope. Thought I was dead for a second. I peeled off my hat, my glasses and my work short in .5 seconds as I backed away from the car lmao.
I seem to have to bleed my civic once every 3-600 miles. Not sure why yet. Just sent it in for a head gasket they replaced the radiator and thermostat saying it was full of rock hard stuff. Like rock candy. From mixing coolants apparently.
You need to bleed the air out of your cooling system otherwise the temp will get super hot at idle. You can buy a radiator bleeding system on Amazon for less than $20. You need to park your car an upward angle to do this procedure. Good Luck!!
Do it “yo damn self!” LOVE IT, and thank you for this. Can’t wait to try it!
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!
Your coolant has the same symptom as I have after drinking too much Pepsi ;)
Hey brother. Good video. Thank you for posting this, saves me time and money!
Thanks bro good video helped me out and it's cold this winter
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 🙏🏻
I got to try this. I put my heat up to 90 but the cold air flows threw. Then while I drive for like 10 min a bit of warm air comes threw hope this works.
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.
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.
Hey thank you for this video. I hate issues and it always seems if you want it done right, better do it your self.
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
Thanx for the video! Congratulations on a job well done and showing that dealers are not perfect either!
2003 Cadillac DeVille burping the coolant system
Thanks for taking the time to teach us all!🙋
Try increasing the Engine speed to 1500 rpm for brief periods and make sure the cooling fans come on twice.
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.
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'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.
Ningishzidda Shar I have an infiniti (owned by Nissan) and ever since having my water pump fixed, I’ve had to do this every couple months. Not sure why it continues to happen
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.
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
You're speaking from experience? Specifically with the Nissan pathfinder/xtera/frontier?
that seems to make sense, to keep that expansion tank on max... because there's a hose that leads right to there from the heater hose assembly/junction next to the core ports.
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.
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.
I'm having that same problem right now I need to try this.
Here for results
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. 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.
...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!
Thank you! This Fixed my pathfinder!!!
No heat, plenty of air, hot hoses to core, but no heat. Maybe , like you said, "too much air in water hoses! 😃
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?
Did you figure it out? I need to do this and have same question
@@mississippiafterdark you need to buy a funnel they're cheap they have the right nozzle to fit in to radiator as mine has a slant right on the inside of the rad. As for the rest im not %100. Pretty sure you fill it and start it and a bunch is gonna come pouring out so it's good to have a nice big funnel or something you can tip it into when it overflows the funnel Because radiator fluid expands heats up. Then once you do everything it tells you to do and get the bubbles out you need to I believe make sure it's full again after its cool down. Make sure you rev your engine up to 2rpm for a bit i forgot to do that step and i failed my 1st attempt
Update : second attempt is a Success! this time for some reason it didn't overflow on me in my small funnel.
I got lots of heat now at idle. Thanks to the maker of the video.
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.
That Worked! All I had to do was put some fluid in it, and burp it... Now She is Happy!
So i have a question about yout video. I notice that your oil pressure gauge was reading low. The oil pressure is shows good whne the engine is cold at idle and when it warms up the the oil pressure on the guage starts to drop at idle. when the engine is at 3 to4 the oil pressure shows good on the gauge. The reason i ask is that my 2005 is doing the samething . it that a normal thing with pathfinders?
Do u let ur car run until the thermostat open before turning the heat on? And watch if the fan turns on?
Learn to do it your self my brother and don't listen to those fake people.
Thank you for your video it really help me
Thank you!
Last night, Travis and I put in the new heater core.
Good video!!! Thanks. Taught me something i had forgotten.
What happens when the thermostat opens and then the coolant is boiling out of radiator with the cap off?
This video saved my hide. Thanks
thanks for helping for posting this help me a lot ...!
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.
uhh engrish?
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
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.
Hello mate.i got an mercedes benz a class a 170..2005...mine blow air but dont come warm air..what i can do?all works before to i go in holliday,when i comeback give low warm air,but now it stop give warn air inside the cabin.
How long did it bubble for? I have a 2017 frontier and from what I read in a frontier forum our trucks will keep bubbling due to the pressurized reservoir tank. What was your experience? Thanks brotha!
need to do Coolant Air Purge, does the engine need to be cold or can I drive to a place which has a ramp like 7 km away ??
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
Thanks for the vid man! I have to try this. I gots to get me some heat!!!!
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 need to bleed the air out of your cooling system otherwise the temp will get super hot at idle. You can buy a radiator bleeding system on Amazon for less than $20. You need to park your car an upward angle to do this procedure. Good Luck!!
thanks for the video! I need to do this after replacing my radiator, and I'm getting no heat.
Did you Jack up the front of the car to help the bubbles come out?
My defrost want defrost the windshield if I start my frontier but soon as I get in it and start to drive it starts blowing the warm air. Will doing this fix my problem?
Thanks for the video man!! Helped save me some money. That was way easy
The overflow is actually the pressure side wouldn’t that cause air to enter the system.
Do this work on cars with bleeder valves already? Is this a short cut without bleeding from the bleeder valve
What you do when time to remove funnel and all that coolant is in there??
Yea I wonder same thing do u jus pull out the funnel let it fall all over and cap it ??? Seriously though I actually want to kno
mgoodell I seen someone wrap a towel around a screwdriver and put it down inside the hole to plug it up and quickly pulled the funnel up
@@obe1canobe146 that exactly how you do it you making you a plug out of a screwdriver with a rag and poke it down in the funnel hole and pull it out quickly.
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.
Hi. I just bought a 2018 Nissan Frontier. My heater will blow warm and then cool. I took it in and they told me that there is a automatic sensor in the truck and it will regulate it self...crazy thing is I don’t have it on the auto system...I think they are lying to me cause it’s easier to send me away then fix my truck...did you have something similar? Blowing warm and then all of a sudden cool air?
Great vid, very helpful. Thank you!
so what do i do with the antifreeze after all th air comes out? does it just flow down?
It should flow down. If not. Stick rag in funnel with screwdriver. Put excess in reservoir
I feel like i am on hallucinogens looking at your video your camera is distorting lol.
Great video ! It took care of my problem...👍🏻👍🏻
how do you burp your radiator if there is no radiator cap like yours? I have a 2005 explorer and the only cap i have is on the reservoir
'So much for listening to those jokers' lol. Same story every day.
See that's exactly what I'm talkin about I have this PT cruiser it overheats but they replaced everything and I don't think they got all the air out of the system and they keep saying it's a head gasket but I don't think so. like your video at idle I don't have no heat but when I rev the engine I get heat I'm wondering could that be the issue I guess I'll have to do it my damn self 😤😒😉👊💪 great video it gives me Faith hopefully it's not the head gasket 🤔😨😢😉👊💪💯
u r right
I did this today and It worked temporarily but after removing the funnel and putting cap back on I’m still having the same issue. Are we supposed to fill the funnel with antifreeze before doing this? Also my funnel wasn’t tight and I kept squeezing the hose after pressing the gas pedal. Repeated doing this for an hour and still no luck 😢
Thanks for the video, going to give it a go this weekend
I put coolant in last night after work (1998 dodge neon) drove home woke up this morning my ac and heat both don’t work I live in Alberta I couldn’t even drive this morning it was to cold and couldn’t see is there bubbles in my think I will try the steps in video
thanks for an easy explanation sir...
Good job...followed to the T. Worked out. Thanks!
