Ford Quick Tips #69: The Trick to Purging Air From Your Cooling System

[@deatraallen4359]

I'm a DIY big time female. I have to say your video is the most professional, informative, and basically simple video I have found so far. I replaced the thermostat on a friend's Ford Escape last night and for the first time ever I can't get heat and I'm overheating. I've replaced many thermostats and haven't ran into this before. So I turn to You tube after few videos of men in chopped up tee shirts and babbling nonsense I find your video. Very professional looking and so very informative. I rushed out tried it. After running 3 cycles I had heat and after a 15 minute drive no overheating!! Thank you so much for your video and sharing your knowledge.

Thank you so much. In my 2010 fusion SE 2.5 gas my water pump started leaking while I was on the highway. I eventually got it home using 7 gal of water over the course of 2 hours. I changed the water pump, thermostat, and serpentine belt. It was so much work for me at home. I was finally done. Exhausted. Glad it was done. I left to test it. Overheated. I was so angry. Eventually got back home. Searched google and found this video and tried out your process AND IT WORKED! Thank the lord!! You are a life saver. I can’t thank you enough.

[@donatellonabotti2299]

Your 6 year old video paid off for me. Replaced the radiator in my 2017 F150 5.0L yesterday and ran into the no heat issue when I was done. I tried this method this morning and it seems to have fixed the problem. I wouldn't have thought to do this on my own so I'm very glad you shared it with us.

[@alexhero01]

This helped tremendously. I had a friend who had someone change the lower radiator hose because the car was overheating. Turned out it was a bad water pump, but there was a ton of air in the system. A shop told her it was a bad head gasket and wanted 3k to change without even seeing it. I changed the water pump and bled the system. It fixed the problem after a few times of cycling the vehicle. Thanks for the videos.

[@captainchrisfishing]

Good thing they make a kit to put into the top of the water box u fil it with blue fluid and hook it to a vacuum line and if said blue liquid changes to a yellow green color it is in fact a bad head gasket

[@kevinhancock4064]

Sounds almost close to my issue . Everything been replaced in last 2 years but the pump . Garage have done loads of checks getting ut tomorrow . I had temp high after taking Mrs to work and coolant had sprayed from overflow onto engine ....its going back in once cooled though .... it didn't lose much as I bought some more to top up . Garage say its flowing etc its odd . Dealers method is rev once warm 2500 revs 5 mins then 3000 revs 5 seconds ..whether the garage done if that way I don't know . Rad new 2 years ago. New coolant sensor /term under a year ago ..New cap hg also hg was done say June or just before last year can't recall exactly . They 1st thought air pocket then cap . I'm miffed

[@reccomp8544]

Thank you! This process cleared some of the air but not enough to totally fix this problem with my 2008 escape after I replaced the thermostat. Then I thought, I need to get my radiator higher than the rest of the suv. I pulled it up on a very steep grade, tried the process one more time. Problem fixed!

[@HappyCamper1992]

Man I gotta thank you so much. Used this video here when doing coolant service on my wife’s 2014 flex with the 3.5 non turbo. Thanks to this and the tune up video as well as the video on the different types of motorcraft coolant things were a absolute breeze and I hate working on cars but with your info I was able to update the coolant to the new OAT yellow and followed your instructions and it wasn’t bad at all. Let me say this to re enforce your Motorcraft parts only statement. I got some counterfeit fuel filters for my power stroke and just as soon as I installed them the truck would not start or run. Fuel starvation. Costly lesson learned when i had to go buy Motorcraft brand filters at autozone at 100 bucks. Won’t ever do that again. Thanks Ford God

[@baxrok2.]

Just ran into this problem after a 2.5L swap. Used a similar procedure. Run at 2500 for 30 secs then 3500 for 30 secs. Rest. Repeat until overheating stops and heater is operating. Your procedure is surely the best way to go though. Just sharing my experience. Thanks for sharing this Brian!

[@FordTechMakuloco]

This is actually a procedure listed in one of the Ford workshop manuals I can attest it has worked very well for me in the past either way the idea is that continuous push.

[@gand7053]

I cant even begin to explain how much this video helped me out. I just replaced the thermostat on an 09 ford focus and it felt like I was running into one problem after the other. Such a pain to replace these things on these cars especially if you're a big guy. Anyway, I finally got the new thermostat in and (as its the first time I've replaced one before I didn't know you had to bleed the cooling system of air) the engine was overheating. I wasn't getting any hot air, the engine wasn't cooling down, and as I was about to just take it to a shop, I found this video, did as you said, and after 15 minutes or so, I started feeling heat out of the vents at idle, the engine was no longer overheating, and after I disconnected the battery (due to some corrosion) the check engine light went off. The car is once again in perfect working order and I can go get this thing smogged. Thanks for the help!

[@darrellsykes7746]

I'm having this issue now. Girlfriends Fusion belt serpentine belt broke or came off (never found the belt) so replaced it and the car started overheating and no heat so I thought maybe the thermostat crapped out at the same time so changed it and still no heat and overheating plus coolant not going down in the overflow tank even though it all emptied out when I changed the thermostat. Going to try this in the morning, would do it now but the car is at AutoZone, lol. Was about to replace the water pump thinking maybe the belt issue caused an issue with that. Up until the belt issue the car had no heat or overheating issue.

You solved my problem. I was getting no heat at all. I thought the de-gas bottle was full because I just looked at it and think it's full. When I removed the cap I found out that the antifreeze just stained the bottle like red sauce in Tupperware . It was bone dry. So I followed your steps and I had to keep putting in antifreeze in it to keep it above the fill line. Now I have heat at idle, and while driving. Thanks man your the best!!!!

[@jamiegodden3241]

Once I get heat ive never had a problem afterwards. That being said I have spent a lot of time struggling with tougher cooling systems. As always your suggested methods improve my ability to work on cars. Many thanks and keep up the good work.

[@boomerguy9935]

When I bought my new-to-me 2008 Escape 3.0 V6, I changed all the fluids because I didn't know the history of type and frequency of changes. This included having my local mechanic friend use a professional coolant flush machine which transfers the new coolant in while the old coolant is discharging. I've done this with other vehicles when I was changing coolant of different colors. I never, ever mix colors! Seeing this video assures me that I did the right thing. I had absolutely no problems with the heater temperature, engine temperature or losing coolant level in the reservoir. Yes, it was a little expensive, but well worth it. Thank you for this video!

[@danielrombach11]

Thanks for the video. Wife's 2012 escape was overheating. Replaced thermostat and purged the air from system with your technique. Runs fine now without overheating.

[@lohithadewa2570]

Lived with a water fall sound in the new car about a year. Dealer couldn't fix it either. Your method fixed it like a charm. Thank you.

[@theowlsofouterheaven]

Did you have a Fusion as well? I have that lovely waterfall sound upon starting. Did you overheat any? I lose heat at idle/low speeds and overheat. When driven, heat goes down and I have heat again. This car is the death of me.

[@DreamZzZz999]

Wow! For the 1st time ever. After replacing the thermostat in my daughters 05 Ford 500 I experienced this. No heat and over heating. I figured it might be air but really didn't know what else to do to get it out. This worked perfectly. Thanks for sharing Ford tec!😀

[@slowkidsatplay8703]

It took many times on a steep driveway. But it worked! The vacuum system would be the best way but if ur on a budget this does work. It took me about 10 cycles of doing this. Getting that sloshing thru the heater core to go away. I tried everyrhing after changing thermostat. Thanks man.

[@slowkidsatplay8703]

Also have a 2.5 2010 fusion

[@nprest8997]

Wow. I've looked for some bleeder point and was almost ready to take my heater core loose and back flow to clean it out. I was getting decent heat at fast idle and driving, but not like before. That's when I realized the core was clean but not getting the flow through it. This tip to bleed worked great for me. Thanks man. I've gotta watch more if your videos.

[@Wildlos76]

Once again you SIR are a genius. Thank you so much. This happened when my wife's car had a slip in the serpentine belt and somehow got air in the system. After I changed the belt I couldn't find the reason it was overheating. Did this burp method 5xs and its back to normal. Thanks for all you do.

[@fordflexin2009]

Just did a complete timing job on my 14 Explorer Sport. Watched many of your videos on the 3.5l. I have to say we all appreciate the videos! Keep up the great work.

[@TheJoefussGarage]

Just did stepmoms 2010 2.5 Fusion, cyl head coolant outlet fitting, and did the valve cover gasket set as well. Watched vids of yours for both of these jobs. Moving the wiring harness, for cover job, and this bleeding vid were awesome for the coolant repair... I did use the bleeder fitting, on the coolant outlet block, it did seem to remove quite a bit air itself... That start and stop, and then running the RPM up to 3500, is the the bomb !!!! God bless brother....

[@rogerhobday8369]

This a method that I have used for many years and mainly it works well. I know some systems do need to be vaccumed to get at good result but I am not a fan of the process as it can cause issues with hoses. I would like to add that it is best to not have the coolant pressure cap down tight if the engine is cold as this allows the system to have an area of lower pressure to which the air can move to and escape. As the engine warms up the pressure cap will have to be tighten so coolant is not forced away from hot parts by steam pressure. But slowly release any pressure once the engine is stopped, without fully removing the pressure cap. Always wise find out how far you can unscrew the cap for it not to hold pressure while the system is cold.

[@RTBCUSTOMSLLC]

Was loosing my mind with my car overheating outta nowhere. After watching numerous videos I came across yours. I did process of elimination because I changed a few parts including coolant temp sensor and cylinder head temperature sensor. So since I knew those were brand new and I had no issues with my blower heater motor I tried this. Dude all it took me was 5 minutes, perfect. My heating system is back on point. Thanks bud.

[@kevinhancock4064]

See I'm thinking I need to do this or similar the dealers recommended method. 5 mins @ 2500 revs then 3k revs for 5 seconds . Garage can't find anything wrong ..New cap etc . Most parts renewed in recent months..had coolant spray from overflow onto engine . Dash coolant temp high . Could still be an air pocket they've not sorted properly

[@AlSteel99]

Very well done and informative. Was stumped on why I was overheating after a t-stat replacement and flush of my 04 Expy. Tried EVERYTHING; draining and refilling, burping with the front end elevated on ramps, pulling the new tstat because I thought it was bad, etc. Saw this method and 15 mins later it was back to normal, no overheating, cabin heat was working great. Thanks again!

Man, thank you so much! My wife overheated her f150 last year, filled the reservoir and all was well until it started getting cold a few weeks ago. We flushed the coolant with water for a few hours a night for 3 nights after work (I'm embarrassed to admit the color of the water, thought that was the problem for sure). When it started to come out clean we used commercial flush/cleaner, I tore into the dash after the blend door, it worked fine, then I stumbled upon your video. 10 minutes and I'm sweating in the cab. I don't regret flushing the coolant, but man I'm glad I saw this video before I dug any deeper into the interior. Thanks a million.

Man, thank you SO much for this trick! My 2008 Ford Escape had never had an overheating problem, and then a bad connection led to the fans not running. Next thing I know, my temp gauge is pinning to the Big Bad Red "H", and no cabin heat. I got the fans going, but that only lowered the heat a little bit, and it sometimes pinged back up to Red. I just happened upon your video on a Ford forum and tried the procedure you describe. After 2 cycles, the temp gauge was back to mid-range and the cabin air was blowing hot, hot, hot! I'm stayin' wired to your channel, dude! Thank you!

Brilliant video, it resolved my cold air problem, but i would say that i waited 2 to 3 mins after 3500rpm blasts as i noticed the air came back into the expansion tank way after 1 min, and also i had to repeat the process 7 times! But i still fully did it, so there is no limit on how many times are needed in repeating this. Just do it till its done! But great advice in general and a great video, well done.

[@ezj8262]

I've had my car for a little over three years and it has been running perfectly. I haven't had any major repairs - I just get my oil changed on time. The oil change guy suggested I get a coolant flush, so I did - and only then did I start experiencing issues that my car never had before. Every time I went to fuel up my car I would have starting issues, but I would just crank the car for a little while until it finally started up. After this initial issue at the pump, my car would start everywhere else without any problems - until my next fill up. Then the same problem would repeat all over again. I was told it was the purge valve that needs to be replaced, and I believe it, but I can't help thinking that it has something to do with the coolant flush that was just done. I was basically told that there wasn't a reasonable connection between the coolant flush and my car's issue - and yet it is quite a coincidence to me. Is there any way a coolant flush could cause other such issues with vapors...etc..?

This procedure would have saved my 2008 Taurus X! I learned about the procedure after I experienced so much violent overheating issues that it blew out the water pump main seal on my X. My X was running fine, but at 250K I thought it would be a good idea to flush my cooling system for “preventive” maintenance. So I let Jiffy Lube do it and they (nor I) knew the system had to be purged properly. I experienced nothing but intermittent overheating issues for months afterwards because I didn’t know about this procedure. Finally got so violent that the pressure blew out water pump seal. At that point I had 292K on the car and ended up donating my beloved car to DAV!

[@radman999]

Exactly the method I use. It seems simple but works really well. I have an AirLift too, but never use it. I see lots of guys jack up the front end, use the Lisle rad funnel, etc.

[@johnstewart2381]

Have to admit, I was skeptical, as my air pocket was lodged in the rear heater core of a Toyota Sienna van. But I was out of options - I purged per the procedure in the manual, no luck. I used this procedure, had rear heat again. Thank you!

I have fixed so many things on my vehicles and been able to speak technically with my service writer at the Lincoln Dealership as a result of all of your awesome videos. I asked him about the oil catch can for the 3.5twin turbo eco boost in my 2013 lincoln MKT and he says they have never installed one an any Lincolns with eco boost. My tech encourages me to use good gas and go for an Italian tune up after it gets good and warm. This should keep the chemicals and oil burning off and said that the tuning on the trucks version of the same engine is tuned a bit different. My ecoboost is a powerhouse now after they cleaned the intake with a 3 part cleannig system and reprogrammed the ecm.

I fixed my car with this video, thanks for sharing this information, blessings,

Hello FordTechMakuloco. I'm betting you are a Senior Master. I enjoy your videos. I'm what we would call a mut technician, being that I work on a variety of makes. Anyways, I really enjoy watching your videos on down time. You explain subjects well. I hope your channel blows up. Good luck bud. While I worked for a Ford, Lincoln, Mercury dealership in Ohio, I was a service advisor. I took a break from the tech side to try it. Man, that job will keep you on your toes, warranty administration, extended warranty companies, techs, etc. I did take a 9 year break from the automotive industry. Got back into it in 2010. I missed it. Worked for a Chrysler dealership. Their certifications are 3 levels. 0, 1, 2. Igor half way through 2 and changed jobs. Prior to all this, I worked for Independent franchise owned shops. This particular video was great. Take care. Merry Christmas to you and your Family. Hope you have a great and prosperous New Year.

I have a 2012 Fusion and I could hear bubbles going through something when I would start the car plus the overheating and lack of heat. Did this trick four times and I no longer hear the bubbles and the heat is back at full strength at idle!! Thanks so much for posting a very helpful video!

[@theowlsofouterheaven]

Did this fix hold up? Was your car a 4cylinder SE? I have a 2010 SE and hear bubbles when cranking too. Overheats at idle and loses heat unless it's driven about 50mph then the temp goes down. Did you remove the cap any when revving?

[@vancouverguy]

Massive thanks for this and all your videos! I just changed the coolant on a new to me 2018 F-150. Was blowing cold air and i was thinking i just wrecked the truck i had worked so hard to get. Followed your procedure this morning and fixed!!!

[@andrewcoulter525]

When all else has failed to completely purge air from a cooling system, drive in 1st and 2nd gear in a very hilly suburban area. Keeping the revs anywhere from 3000-5000 rpm while driving up and down steep hills especially while cornering has worked for me to get out that last bit of air and stop the gurgling noise. I find 10 minutes of this driving does the trick. Just keep an eye on your temperature gauge to be safe.

This guy is Awesome

[@FSBQCAS]

you articulate the situation and solutions so fundamentally well, and in such a concise manner, that, I simply enjoyed watching your video, and foremost; for simply the manner in which you presented the content. Great Work! Thank you for making the video and, also, taking the time to read this.. Sincerely and Cheers' "the Polite; Rushing"

[@sabmaster68]

My go to guy since I got a 03 Ford expedition 5.4 engine. Extremely helpful

[@rudejude1000]

Thanks, this worked for my ford escape. I appreciate it, wasn’t wanting to change thermostat or tear anything apart.

[@sgtmunroe]

Thanks, I had to replace my thermostat in my 2013 Ford F-150. Afterwards, I topped off my coolant and thought i was good. Then I had cold air at stops and idle. And would overheat for a few minutes then be ok. This seems to have done the trick. Great tip/video.

[@zekevanderpool1505]

Great video man. Big help to the shade tree mechanic who just changed his own heater core in a 2000 F150. Thanks!

[@bradgann6880]

Same here on a 97 made in 96. This dude knows what's up n can explain best I find on the ol truck. Ford needs him on a commercial.

[@mvc2177]

Hello, I have a 1997 f150 4.6. Do I need to jack up the truck in front and do this procedure?

[@RCHopson]

Thank you this did the trick on my 2000 f150 4.2 after a new radiator install at 251000 miles

[@brianfrancis5548]

This worked for our 2010 Mercury Mariner V6. With the engine completely cold the coolant level was way below the cold fill range and we don't know why. Filled it about 1" above max cold fill as suggested and ran 4 cycles. After the first two cycles there was a lot of air hissing out when the cap was removed. A lot less after the third cycle and nothing audible after the forth. There is a ton of heat coming out now. No maintenance was done on the vehicle. It just started not putting heat into the cabin intermittently. Thanks a lot for the video.

[@dontwanadisplaynameonutube2951]

2010 ford focus, this fixed an issue setting off my p1289 error code CHT sensor. radiator cap was opened a little while it was hot i believe(, i don't think while running). But anyway, the ford reverse flow must have sucked some air into system and boy I was worried since I just bought it from a dealership "as-is". Hope this comment and your video helps more people out there with any similar issue. 3000 rpm in park for 30 seconds did the trick for me, since it barely wanted to hit 3.5.

[@nomanjones4803]

I have a 2010 fusion with a 2.5 and I had to replace the thermostat, all I did when I refilled it was open the vent tube poured the coolant back in and no problems, no overheat and plenty of heat at the vents.

[@dalegoodwin7618]

Thank you for this video! Solved my problem first cycle per your instructions, had been fighting air problem for hours!!

[@jamescawood9352]

You helped me fix a lot of problems on my 2011 Escape. Thanks for sharing your knowledge!

[@MichaelMcNeilg]

Thank you Brian, I'm going to help a friend with his 02 explorer and this is very helpful before tackling it.

[@Sip28]

Did it work?

[@grapeseed427]

Does he knew how many people he saved with this video, a hero

[@baymonearl]

Thanks bud, I replaced the thermostat, water pump and the water outlet valve; and had to purge the system.

[@jagedgem]

2013 Ford Escape 1.6 L Ecoboost- worked on third cycle! Thank you!!!!

[@Flyin69]

My man!!!! Worked beautifully to purge on my 13’ F150 ecoboost. Thank you!!

[@stanleydueck4904]

Did you have heat coming out of vents? My 2015 3.5 ecoboost gets a bit hot when driving uphill, but I do have heat coming out of vents . Could air in system be my problem? My thermostrat was bad, I changed it, truck still gets uncomfortably hot driving uphill

[@joevignolor4u949]

It sounds like this problem is caused by the fact that the top of the heater core is higher than the degas bottle so air is being trapped up there. As such you could simply remove the top hose from the heater core and then plug a funnel into the hose and pour more coolant down into the engine until the coolant just starts to come back out of the open fitting of the heater core. Then just reconnect the hose to the core and all the air would be gone. Basically what you'd be doing is filling the system at its true high point instead of the degas bottle so all the air would have to come out.

[@FordTechMakuloco]

Yes very much so as I explained in the beginning of the video allot of times it is at the highest point. The problem with the method you are describing though is you will still be introducing air into the system by the hose you disconnected creating a bigger problem because that air would eventually circulate through and get trapped again. Same thing with the reverse cooling systems air can be trapped at various places and this is the best way to get them out short of using the vacuum fill tool.

[@joevignolor4u949]

I disagree. Once the cooling system is completely full of liquid up to the highest point no additional air can enter into the system through there. It's the same thing as in older cars if you take the radiator cap off when the radiator is full. Even though the cap is off no air will enter the system if it's already full up to the top and holding coolant. The way air enters the cooling system during servicing is that draining the coolant out of the bottom draws in fresh air from the outside to replace the missing liquid. Typically the replacement air enters the cooling system through the open fill point located somewhere near the top. So as long as the cooling system is closed down below and its full of coolant up to its highest point then having it opened only at the highest point will not let any air in. Therefore, if the cooling system is being filled through the disconnected heater hose the engine and cooling system will gradually fill and the coolant level will rise and the air will be forced out. Eventually the heater core will also fill until excess coolant will start to come out through the open tube. At that point the entire system including the heater core will be full because most of the air will have already been purged out and then you can reconnect the hose and close the system. Any small amounts of air still trapped anywhere in the system will eventually purge out once the coolant begins to circulate. Eventually it will all end up in the degas bottle. Filling this type of system through the heater hose is probably faster and easier than using the vacuum method or cyclically racing and stopping the engine to purge out the air. This is because it will immediately purge most of the air from the engine and the rest of the cooling system before you even start the engine.

[@uniq_vidzbostonmass25]

Hi I just flushed heater core that was clogged and had no heat at all. After de clogging it. I have heat only in city driving, highway it's not hot as it should be. What do u suggest please?

[@BarryAdams777]

Would be nice to plumb in a simple petcock at the highest point. Will never have that issue again.

[@sansanper7562]

Great video! For the 4 cylinder 2.3L, there is a bleeding screw that helps with the bleeding process.

[@Garagehustler]

Where is it located?

[@2muchspl]

Well done!!!! Daughter got into a fender bender (06 Fusion,2.3L) and radiator left the chat.... I'm a old school Chevy boy and couldn't understand why it insta-overheated and had no heat after I repaired it on this brisk 17° day😂
