Can't imagine you'll see this comment, but followed this guidance over the weekend and brought my 20 year old heater from nonfunctional to hot as an oven. Took about 30 gallons and a lot of sediment that looked like pebbles of concrete. The weather is below freezing most mornings now and I'm super appreciative- you've changed my quality of life significantly.

ChrisFix has been saving me thousands of dollars, this guy should get a nobel prize. I have a 2013 dodge Ram 1500 and I had no more heat on driver's side. I went at the dealer and they told me it could be multiple problems and would cost around 2000$ to fix. Decided to try this first and it worked like a charm, simple steps and only cost me 35$. Thank you so much Chris!

[@steverogers8329]

This was a great walkthrough video! I was able to flush out my 2002 Taurus in about 2 hours. My heater core is farther down behind the engine so it was a bit tougher. My heat wasn’t working at all and after flushing the brown sludge for about ten 5gal buckets, the water was finally clear. I found that running the water both directions got more crap out than just the one direction. In any case, now the heat works 100% and I didn’t have to pull my dashboard out to replace the heater core! Your videos are hands down the best walkthroughs I’ve seen on KZbin so keep up the great work!

[@kimberly4891]

Thank you, Chris. Since my Husband has passed I have to do this by myself. Because of you and your detailed instructions, I got the job done all by myself! Actually, it was pretty simple. P.S.: I have a 2000 Dodge Dakota w/V-8 MAGNUM.

[@MARTYMEINEKE53]

Pro tip never disconnect the heater hose from the heater core itself. Disconnect them from the engine. Reason being the hoses may have to be twisted loose for removal and if you snap the neck of the heater core you are in for a big repair. So remove them on the engine or coolant feed instead

[@Patrick94GSR]

yep, I removed the heater pipes from my core when I did an engine-out service a decade ago, and ended up crushing the brass heater core pipes. Ooops. I drove the car with the core bypassed (no heat) for several months before getting a replacement core, and then I had to pull my entire dashboard to replace the core. It was a HUGE PITA!

[@travissmith6210]

Absolutely true

[@loweredexpectations8568]

What if you've got a bypass hose? Will it still flush out?

[@DJPacoRamirez]

Lowered Expectations if you have it bypass, typically your heater cores pipes are exposed, which basically your skipping the first couple of steps. Like mine

[@OcRefrigeration]

[@joehorstthemechanic-lagran3339]

Pretty good video but just a couple of cautions. You want to be very careful when removing the heater hoses from the heater core, if you have an older heater core and you twist the hoses to remove them, it can damage the heater core and then you have no choice but to replace it. Most often we put a short slice at the end of the hose and work it off carefully then cut the slice off the end of the hose and reinstall it after flushing. When those spring clamps are removed they lose spring tension, I have seen them leak when reused. We always install new screw style clamps. Otherwise the video was very informative and flushing does help heater output most of the time.

[@CMGDMovies]

Learned this the hard way, bent up the tip of my heater core on my 3000gt the other day. Going to just get new clamps and make sure they are very secure.

[@Asphaltaperider]

Thanks for that info!!

[@CantonBn]

@joehorstthemechanic-lagran3339 John, you make some good points. But spring type clamps are not used on these systems because they are cheaper. But because they continue to tighten as the material of the hose compresses slightly over time. So you get new clamps -- but not screw type, you do want fresh spring type. But you are absolutely correct about treating the rubber to alloy connection carefully and not yanking around. if you dame the heater core you could be looking at up to $2k repair in replacing a heater core which on a modern car an be a full day expert labor removing entire dash

[@hypurnova]

If your vehicle has one, check the heater control valve while your at it. If there is a lot of buildup in your heater core, your control valve could very easily be blocked/damaged which could cause a lack of/no heat as well. 👍Also, be extra careful not to accidentally bend or pinch your heater cores inlet and outlet tubes as they can be made of brass or aluminum and can be damaged easily which could result in a wicked coolant leak. Hope I helped 😊

[@TrueBlueEG8]

Word to the wise, if you try removing the hoses from your 20 year old heater rad, you will run into serious trouble. My advice is to buy new hose before you attempt this, and cut the old hoses off with a sharp stanley knife, dont pry or twist them off, because you will distort the metal pipes on the heater core, or break the welds/braising inside the car and fill your interior with delicious coolant, I have seen this happen several times on older cars.

A good idea is to have the end of the clear hose in a cup of hot water before pushing it onto the firewall fitting. That will make it much easier to fit as the plastic becomes softer.

We saw quite a few plugged heater cores in the 1998 to 2005 VW Passat. We reversed flushed using a pond pump (Harbor Freight) in a bucket of CLR. Let it run overnight and you would not believe the amount of debris, rust, and crud in the bottom of the bucket. It did not take too long before we ruined the first pond pump so we attached a sump screen to the replacement pump inlet to keep the pumps from getting fouled. It was about a $1000.00 job to replace the heater core and I think we sold the "cleaning/backflush" for $250.00 including the gallon of CLR. Always got good results and was amazed at how much crud came out of the heater core. We of course would not recommend this unless there was clean antifreeze in the coolant system to begin with (already had the standard coolant flush done).

Good job. Quick and to the point explanations while you're doing the job good for you and nice camera work

[@dreamsmith19]

Hey, just so you know, your link to the hose adapter is for a 3/8" I.D. hose, not 5/8".

[@GDCorsa]

Great and helpful as always, merry christmas!

[@chrisfix]

Kallyper Thanks bud! Glad the video was helpful! Merry Christmas to you too!

[@cameronpapple7655]

Just flushed the heater and What a simple and easy way to fix the it. Thanks Chris

[@sbmatt]

Thanks. It worked. I applied your method to my 07 uplander and I now got heat.

[@daboss59]

Chris one thing you might want to consider anytime around any hoses if use a little WD-40 on the inlet on the inside of the hoses when you put them on the different items it'll also help with the release of the hoses later on and sometimes if the hose looks like those two on that Mazda of yours are a little bit old it might be prudent to replace them and use like I say a razor cut it off the nipple and then spray a little WD-40 that way you won't rattle the heater core and break the solder and have a leaking heater core

[@davidhur09]

my relationship so broken not even chris can fix it =(

[@bas12345654321]

Just flush her old blood out and replace with fresh antifreeze.

[@ahsanrafiq8090]

Thanks for the great video , my Hyundai Atos 2007 heater was not working and was giving chilled air, after flushing with pressurised water like you did, all the scale and dirt come out of the outlet hose, now my car heater is giving hot air like a charm, bundle of thanks man....👍👍👍

[@sonnyc3826]

seems easy enough good simple explanation and to the point..i think i need to do this to my truck 2005 chevy silverado i just put coolan tin it and its cold air coming out teh driver side vents eventually it goes to hot but still probably dirty

[@sglenn6]

Thanks Chris! Another Great Video!

[@chrisfix]

Glad the video was helpful!

[@BigGuyReview]

Hey awesome video. I have a 2007 econoline with 450 000 miles on it. The heat is a little low and I will try this. Up north here in Canada the winter can be cruel and cold! We need all the heat we can get out of these heater cores.

[@chrisfix]

Big Guy Review Wow 450k miles is a lot! Nice job keeping her going! Let me know how the flush goes!

[@BigGuyReview]

ya will do.

[@JustyzzG]

What a fucking tank. My Step-Mother has the same van for daycare children.. and it has 380k.

[@BigGuyReview]

ya if you take of most any vehicle it will take care of you.

FarrukGlo CR7 Neechious Teen answer Lol And if you're not a kid it,s even worse Hahaha good luck in life with an attitude as yours!

[@CLOWEN2010]

TY for the video, i flushed my heater core yest because i had no heat at all, after flushing i didn’t think it worked because not much came out of it, well i was wrong, heat works now and it’s bumping at a hot 130 degrees. Keep up the good work!!

[@chrisfix]

I'm glad you got your heat back! Thanks a lot!

[@munozinni]

I did it to my 1988 Chevy 1500 cause not heater at all after that I got better results but I didn’t knew about the way you did it on this video and is an excellent information to know about...gracias!! 😄I already subscribed thank you!!😃

[@fluoridaman2332]

"you're mixing thing's up, you're flushing things out" lmao

[@hugoloza9]

Awesome! Thank you bro. I did it with my dodge journe 2010, it was really bad. Thanks!

[@chrisfix]

Nice!!! Glad the video was helpful!

[@manij1078]

My journey 2009 has luke warm heat driver side and cold passenger side think this will work for me? Thanks

[@AussieNexus7408]

@@manij1078 yeah buddy should help just be careful to not break the barbs off the heater core 👍

[@SpenceWellCki]

Thanks Chris another great video! I’ve had my Mazda B3000 and I’m glad you show me the tips and tricks to fix mine! 🙏🏼🤙🏼

[@robertstone8852]

good video, appreciate how careful, clean and precise you were!

[@ian22222]

So I watched this late last night. Apparently, I had a dream that I tried to flush my heater core, but the water was already clean! 😂

[@waqasmir76]

Thanks for the tutorial

[@chrisfix]

+Waqas Aziz No problem!

[@opipharma2009]

I think this is one of best videos ever about this job... I think I watched it about 20 times 😍😍

[@ELECTROMARINEMANIA]

im from india your vedios more help full thank you buddy

[@chrisfix]

Im glad the videos are helpful!

[@therealbacaboo]

Helpful. Thanks!!

[@dabigboom8140]

Thank you so much! I just did a timing belt job on my 2004 tacoma and changed a ton of other stuff too like the water pump. Which meant I had the refill the coolant, so I decided to put the old coolant back in with some radiator flush for a few days and flush it with fresh coolant. I flushed the new coolant, and on the test drive I noticed my heater stopped working... I had a new thermostat and everything so it could only really mean the core was clogged... I really didn't want to spend the time and money to change the core, especially since I just spent so much on the TB job. I tried this method, and sure enough some plastic bits came out along with some dirt and now the heater is working flawlessly again! I'm the type of lazy that likes to change as much stuff as possible that might need it while I'm already in there so I don't have to do it again. So you probably just saved me $600 and 8 hours

[@kadeshalatreese2363]

Was able to get my heat fixed today with your step by step video!!

[@p3l1k44n1]

I did this to my old dodge aspen and the water was clear.. But then i reversed the order and pumped the exhaust port with water and inlet as an exhaust and more brown sludge came out.. then i reversed the order again and even more brown sludge.. After that it was clean tho.

[@Dee-hi5zj]

EXACTLY my experience with a Volare (same type system) I had a 5 gallon bucket of ultra-sludge... And afterward, the heater cooked everybody in the car to a nice lobster-red!

[@moby271]

You did it the right way. Chris could learn from you.

[@ajg2040]

Donny B.. Lobster red... Lmao

[@evolutionj]

passengers cooked af

[@ThomasFarquhar2]

Ford M Garage you don't have to end every sentence with tho tho! You don't have to end every sentence with tho tho

[@Clearanceman2]

Wow, never even heard of this. Both cars still good heat at 256,000 and 300,000 miles. But I do change radiator fluid before it gets dirty.

[@SpartanX360]

I need this ASAP winter already here, Awesome fix thanks Chrisfix!

[@funkyprepper]

Cool video as always Chris. My truck had head gasket seal fluid in the head. My heater core is clogged. Highly possible it will need replacing as its hard to flush out by the sound of it

[@chrisfix]

Thanks a lot! And I would try this method first even if it seems hard to flush, definitely beats having to go in to replace the heater core

[@Bigone818]

I don't know if you will see this or not.but does your heater blow hot air.i used head gasket fluid also wish I didn't now ill never use it again

[@daisy8luke]

Holy crap! I have a 2012 Jeep Wrangler , and the heater is blowing mildly warm air. I looked it up and found multiple complaints on this Jeep. They had all these horror stories about replacing multiple items and costing thousands of dollars over time, but the manufacturer says the problem is casting sand. I wonder if all these people spending all that money could have just flushed out their heater cores instead of spending their life savings to make the heater work!Seriously, thank you for posting this video! I'm doing it this weekend !!!

[@chrisfix]

+daisy8luke good luck! Hopefully it works! Let me know how it goes!

[@nati2054]

Update?

[@adamsaquatics3332]

Also patiently awaiting an update. Lol

[@richardharris492]

daisy8luke trust me of it were that simple you wouldn't be the first to find out, I'm sure someone attempted a flush at some point, SMH

[@MrTHL1]

didn't work huh? lol

[@hellcatredeye-g6582]

Just by the discoloration of the anti-freeze you should've flushed the radiator and engine at the same time otherwise just going to get contaminated all over again using the same old anti-freeze in the radiator when I do this at my shop it's just best to change all the any freeze flush everything otherwise just half the job . You Gotta know the radiator water pump heater is all connected same system

[@chrisfix]

+Ken Cook thanks for sharing. Watch my "superflush your cooling system" video.

[@williamjenkins871]

I took notice when the video started how "discolored" the coolant was. At the end he is concerned about proper 50/50 mix and not flushing radiator.

[@dufus2273]

yeah , I just said this very thing.

[@OcRefrigeration]

fact !

[@thewayofbass2534]

Surprisingly this actually works! My recent used car I bought barely blew warm air till a reverse flush and now at idle it blows 120 degree air. I can't have full heat on for too long now its way to warm.

[@alanshezar8163]

Amazing. You explained and demonstrated this really well.
