This Is How To Unclog Your Heater Core For Free In Minutes At Home | Easy 

That’s why I love RU-vid, it allows young men like me learn, growing up with no father figure and no one to show me these kind of things really was a downfall but I’m learning.

I appreciate your instructions and how well your video was created! It’s people like you who are living life through service and kindness, and that deserves respect. Thank you!

I gotta say I was skeptical as hell, but I tried this and the car I was working on went from no heat whatsoever to working perfectly. I didn't even need any fittings just held my hose sprayer to the hose of the heater core. Awesome video.

You are the man. Straight forward, no BS or annoying skits you have to suffer through until making it to the point where you get to the reason for clicking on the video. If I knew where you were I'd give you a nice crispy bill for a tip. Thank you Boss

Just saying thanks this worked for me. I'm alone out here and didn't know what to do. I had trouble getting one of the hoses off the heater core, eventually I got it off, and I didn't have access to a garden hose, so I used a pressure washer at a car wash. With so many shady and expensive repair shops out there, information like this can save people a bundle.

This is an excellent, high quality, no nonsense, helpful video.

Last winter I had heat that was barely lukewarm. After scouring the internet for a solution to my problem and checking every other possible cause, I figured I'd give this a try. To my amazement it worked like a charm, the heater is blowing HOT now. Thank you for a simple, straight forward video. And BTW, I have plier envy. Those pliers would come in handy for lots of situations.

You really seem like an honest mechanic I wished I could find you here in N. Tx because I have been lied to and robbed by a couple of mechanics and I do believe this is the problem with my car SO I REALLY APPRECIATE YOU FOR THIS VIDEO cus I'll try to do the work myself. THANK YOU!

You are the man! Just did this on my 2004 Honda Element cuz I was getting little to no heat. Took about 30 mins total and heater blows super hot now. Thanks for saving me money and time!

I recently paid $400 for a shop to do something, and I'm pretty sure this is all they did. But I think it needs to be done again, and I'll be damned if I pay them another $400 for this. Gonna try this asap! Fingers crossed!

I watched a couple of videos from different people and you just have a good way of talking that’s easy to understand and follow. Everyone can teach “how” but you show “why” you do things a certain way. Thanks for the video.

We did ours recently...there is a tool specifically designed for the tension hose clamps, I highly recommend getting one, so much easier. Also, different cars have various psi limits for their heater cores so I'd recommend staring with a light flow of water and keep increasing slightly until clog is dislodged.

Great video. Many years ago I put 'leak stopper' in an old Renault 5. Stopped the radiator leak, but performance was terrible in the cold weather. Vehicle had a water heated inlet manifold and the small pipes that fed it had got blocked by the leak stopper gunk! I replaced the radiator and spent a while blasting out the system with a hose. Happy days! 😀

this has by far been the best video and to the point that i have seen in a long time!!! going to try it tonight

What a great video! The information was easy by understand, the film and edit was on point, and it was to the point. Thank you for sharing! 🙌🏾💯

Thanks. Appreciate it. Did a coolant change on my wife's car today and no heat. Coolant was filthy and probably clogged the heater core. Seeing how simple it is to clean this will be my first step. I got hot coolant going in but the out house is cool. So probably clogged. Thanks again

Pure genius.... and if doesn’t work on my car-you’re still a genius!😊

As many others I was doubtful about it since I used some bar's leak head gasket repair kit, I thought this product had gone through the tiny water passages but it only clogged the entrance of every small passage, when I pushed water hard everything came out, it was so clogged! water was having a hard time going through pretty bad, after flushing it several times water could go through the heater core so freely. I was about to replace the heater core, it's a big job, you have to remove the entire dashboard, it was going to be a mess, thank you Sir, much appreciated

Thank you for your video. I had a clamped on male hose fitting like you so I just took that male end off and clamped my hose to one of my heater core tubes. One-man operation. Easy peasy.

This cat’s personality just earned him a solid subscribe

Good look. I wish I knew this 15 yrs ago. I spent 9 hrs in the snow replacing a heater core. I had heat afterwards but the process sucked to say the least.

Thanks so much for your time and patience for this demonstration and knowledge

Thank you, You just saved me €500 by not having to buy a new Heater Core from Toyota !!!! Thanks again from Dublin Ireland 🇮🇪

Thank you for the video. You kept it simple and easy. Well-informed video.

Have used this method before and it works . Another car has to be done hopefully it works as well as the last time

Omg, dude you just helped me fix my heater 😁😁 Thank you Do Much!!!

Very informative and easy to understand. Single, fixed income, so I have to fix my own problems. I appreciate your video and your help. Will be watching more.😊

I like you already my friend! It’s cool you went on RU-vid and showed us how to do this…… you’re a good man!

Thumbs up for being clear and concise on exactly what to do and how to do it. I will be using a drill powered pump and buckets to circulate some cleaner designed for this purpose. I will ether use CLR or Irontite ThoroFlush with as hot of water as i can get and circulate it for a while. Then I will do a final flush exactly as you have done.

Great tip, thank you. Excellent job with the video, you are really good with the way you show how to do things, clear, easy to understand and better yet, a fantastic tip that saves you a lot of dough! Thanks for the tip and the lesson.

Thank You for that valuable tip Very well produced video I’m sure you saved a lot of people some money. 👍👍

Damn great! Instead of ripping out the entire damn dashboard to get to the heater core itself! Love ya, bro!

Great video bro! You demonstrated the "3S" principle to the tee. "SHORT, SWEET, AND SIMPLE!

awesome man thanks I will try this out on my old lady's van!

And you're right about the gasket repair. Most people pour it in one shot all right in at once. You have to pour a little at a time till the leak stops. Pouring it all in at once is not only a waste but gets in all sorts of places its not meant for.

I had a problem with my prius no heat and follow this I solved my problem. Great video and explanation!!! Thank you

I am going to try this on my 2014 Chevy Silverado Lt v8 ! I we I'll let you now how it goes ! Thanks bro !

Good video. Its good not having a perfect seal when pushing the water through the heater core because you would not want to burst the heater core and than having the large job and experience of having the heater core replaced. But cleaning the heater core is a great idea and makes a great improvement to interior heating. I sort of starting to maybe like the stock spring band style hose clamps thay can seem faster and don't need Re tightening

Thanks man! I am going to give this a try on my old Malibu 🌈😃🤙

Thank you… I tried it and it worked and I got heat…and it saved me $500

Nice work! Thank you for these tips, I will give this a try on my heater core.

I just flushed it as in the video and heating started working like magic. Thank you.

Thank You for a Easy Way without all the Drama of unclogging the heater core.

You are indeed the man. I’m going to try this next weekend. Thanks for posting

Used the exact same Bar's sealant last night and instantly after following the instructions, the heater stopped blowing heat and my car starting overheating like the engine was about to blow up. I'm still not 100% that this is the only problem, bit I'm sure this video has something to do with how to fix it. Thanks.

Great information good clear presentation

That tapered end is a great idea . Most people have 60 lbs. of water pressure . The cooling system operates around 17 lbs. MAX . Restricting that pressure is a good idea . Those caps from Lucas or similar additives mat fit .

This is the best video I've seen on this subject thank you so much

I’ve done something similar to this but I used a trigger type hose sprayer that has a threaded end on it you can attach another short garden his to which enables you to pull the trigger on the hose end while you hold the hose with the other hand.

Chilled explanation , thanks

Great video! Good information, very professional

Water balloon attachment, good thinking… Thanks for the video

To the point. Great job! 👍

This totally worked! I now have proper heat!

Great video thank you so much for showing how to do the flush, it worked just like you said. Looking forward for more helpful info 👍

Great video, thanks for the information!

Thanks for the video! On my Citroen berlingo van the pipes are so difficult to get to 😅 I’ve replaced thermostat etc, but I feel the core is clogged, as the heater in the cabin only heats the window and not the footwell very well! Probably try this at some point when it gets warmer here in the UK

They use those clamps because of heat expansion, keeps the same tension as the part expands with heat, also contracts when it cools so the piping doesnt crack or distort. 👌🏼

Would there be residual liquid/coolant in the pipes before you take the clamps off? Does it have to get emptied before you do anything?

I'm game, thanks my guy will be checking in to this tomorrow

Thank you from Israel 🙏

Thanks brother!!! You make this task so simple!! Great easy to follow instructions!! GOD bless!!

Nicely explained and demonstrated! I will try this as I did use the head gasket leak stuff and the heater now blows, but no heat :( Thanks for the video OXMAN!

Thank you, I'm definitely going to try this right now.

Wow and I just paid 600 hundred dollars for this Job,thanks

Really respectable job on the video. Thanks, G

Sweet and clear video. You got style bro

Modern stop leak additives typically do not clog heater cores, "but" they do coat their passages, and any of that at all, or scaling, will significantly reduce the heat transfer performance. You can flush your core and see great flow through of clean water and still end up with little heat to show for it. You can use CLR, but it needs to be flushed very well or it can eat at seals and head gaskets.

Just found your video today,, thank you for your good knowledge, MY Question is I just put a thermostat in my Lexus gs 300,, in still no heat,so a mechanic I know don't want to change my heatercoil,again thank you King,, I will try this weekend

I thought I was going to have to spend 2000$ to replace my heater core, but thought I would try this first. This was such a helpful video. I ended up removing the clips on the other side of the hoses. Flushed twice and now heater is working perfectly. Thank you!!!

This video was soo helpful man , I have a Tacoma giving me issues and this looks like a good solution for that, thank you!

That is not a "fastener" on the hose it is a CLAMP, specifically a "Cat Spring Band Clamp". If you want the type that have a screw to loosen or tighten they are simply called a Cat Clamp. After you remove that small hose you easily switch the clamp for a screw type BUT make sure you will be able to get it off in the future. Any auto supply store or hardware store has them.

Those fasteners are such a pain! Thank for the video man. You got a sub for sure. Also what was that knocking I heard when you started the vehicle? I know it's been two years but I would like to know what to Identify when I hear it! Thanks

Can this cause water to leak into the floor of my car? I just got my head gasket replaced but now my car is leaking a lot of water underneath and on the passenger side carpet. The radiator hose had some swelling but my mechanic said it’s fine now? they say the carpet being well is just from the rain. Which makes no sense. I don’t have a sunroof and the weather strips on my doors are fine..

Mine was broke for 3 years until i moved, driving over road bumps in the road to slow u down, fixed it.

I did this once this summer changed theromostat,water pump,and radiator still no heat and now it's-20°-40 ° so this will be difficult in this weather havent had any heat since I got it brutally cold out

I used some CLR. Make sure it saturates for about an hour. Clean as a whistle.. (well if the whistle was clean to begin with) (as clean as a clean whistle)

i saw someone do the cold side so the water is going in the opposite direction that it normally does. you can the reverse it. they also dumped some CLR in there and let it sit in the heater core for a while and then flushed it...

Thanks man you are very good at telling how , to do it it's going to help an you allso have a blessed day

Very well done video , Thank You.

brilliant idea by a good man.

And sometimes the other ends of the hose are more handy to use or if you are really safe and careful the hose downtown.

YOU'RE A LIFESAVER!!!! I HAD LITTLE HEAT COMING OUT BUT AFTER THIS METHOD IT BLOWS HOT AIR! I'M NO LONGER FREEZING MY LONG DRIVES IN THE WINTERTIME NOW! A MILLION THANKS!

Great job keep it simple thanks

Very well put together video. 10/10

Blessings and thank you much for the video, will definitely try it. God Bless

Great idea, Good job. My car is overheating, I changed everything, water pump, thermostat, and the radiator, its still overheating. I Didn't do this yet. I'll advise. 2006 Hyundai Sonata.

Brilliant video, thank you so much. Very helpful.

saved me some bucks on my 09 impala....thanks much

Dudes wife is like "where tha damn cap mustard cap keep going. Lol. You make it look easy. Thanks for the upload.

BIG help! Thanks

I’m going to try this. Had to replace my radiator on my Ram and it overheated. Bled the air out and now the temp gauge stays low and I have no heat. How do you know which hose is into the core and which is out?

works on my jeep xj. Great tip thanks

Thanks for making this video. Huge help! 👍

I'm going to try this tomorrow on my 2002 camry LE. I'm not even sure if the tubes I've identified are the right ones because they're placed vertically above and below eachother instead of side by side like the car in the video. I'm really hoping this works for my car is completely undrivable due to it over heating. The fact that no heat is coming thru when I try the heater all the way on trick (seems to make the tempature meter go even higher) makes me think that it's just clogged. My radiator hose burst opened because of all the pressure that built up and I'm hoping this prevents it from happening again for I do not have any funds to take it to a mechanic.

Thanks, I'm going to try this for myself.

Great tutorial! Look forward to the next!

Trying this tomorrow on my 2005 audi a4 cabriolet. Its only blowing stone cold air and its winter here in ireland. Fingers crossed 🤞

Thank you bro.. just try it and it worked

Thank you very much you saved me some cash thanks again
