- In this video I use an electric pump to flush a heater core in a 2002 Jeep Liberty. I used a mixture of 50% CLR and 50% hot water. I set up a system to constantly circulate the mixture through the heater core for an extended length of time. The results were fantastic. The heat is working great now.

Hey, thanks for the awesome video! My daughter's 2002 Jeep Liberty was not heating and had a leaky radiator. I bought the same pump you used at Harbor Freight ($64.99), mixed CLR at about 30 water/70 CLR mix, and switched the flow about every 20-30 minutes for about 3-4 hours. Then rinsed with water. I just used a small bucket and some HF clamps to hold the hoses. Needless to say, this worked perfectly. The Liberty has heat, which is good in MN, and I didn't have to tear out the dash, AC, etc. Again, thanks for sharing!
Thanks for the video. I went out and purchased the same pump and used the same procedure on a 2008 Tundra with a heater core that has been plugged on the left side. Worked extremely well. Took about an hour of working it both ways through the core but it now has heat. Great job thanks for sharing!
I did the clr flush on a f150 2001for the heater core with good results. Used a small fountain/ pond pump from harbor freight for 9 bucks. Ran it about 2 hours and flushed out with clear hose water for 5 mins after. 👍 thanks for the help.
Glad it worked for you too! 🙂👍
Wow! Those pump motor brushes are yuuuuuge! I'm impressed. They definitely don't build cars for serviceability these days. I'd have been too scared to put CLR in my heater core figuring it would eat thru and end up all over my floor. Glad to know it'll work! I'll definitely keep that trick in my back pocket. Thanks for the video!
burningdinosaurs, I was surprised at the size of the brushes too. By the time those wear out, the pump housing will probably be shot. The CLR really worked well. It's definitely worth a try if your heater core is plugged up. Thanks for watching! 🙂👍
Ignore the haters! This process is exactly what I have been looking for. I just went and purchsed all I needed from Hard to fart (lol) and Ill let ya know how it works. Thank you for taking the time to upload this video.
This is the best video I have seen on cleaning heater core
Wow thank you I did the exact flush on my 2012 jeep liberty it clogs every year terrible design by jeep. Now my heater is hott🔥🔥🔥
Man I feel you because I have a 2008 Jeep Liberty and the heater core is clogged with hardly any heat and you know as well as I that it’s a nightmare to get to to change. I tried back flushing but was scared it would burst it as it’s only meant for 10 psi. Anyways how is it still holding up? Any issues with this? I’m scared CRL will eat the aluminum heater core up? Thanks
@@ghostley8155 yes I still have heat. I was nervous as well. I wouldn't turn the pump on all the way till the heater core became unclogged. As long as you rinse the heater core out with water in the end you should be fine. I'll probably give it another flush after summer. Good luck.
@@briangamroth3506 thank you!
I wouldn't be scared of the flush. Worse comes to worse you were potentially going to replace the faulty core anyway. So if the flush works, big win. If it doesn't, move on to replacing.
I used to do flushes like this on big heat exchangers, we used acid then circulated a neutralizer. It worked pretty good.
Jerry Stott, it worked very well on this heater core too. After the CLR, I flushed it for several minutes with clean water. Thanks for watching! 🙂👍
So if the core is really plugged how much pressure can that pump develop? A typical heating system only holds about 10psi. You can easily pop your core pressurizing it with a garden hose or electric pump.
I have 2 below zero this Tuesday morning. I hope it doesn’t get down as far as you. Tell your daughter to stay warm. I suppose your son rides with her to school too. Have a nice day.
walter mattson, it was 7 degrees Fahrenheit this morning. I'm already ready for spring. Hope you have a nice day as well. Thanks for watching! 🙂👍
I did this today. At the end, I have heat again. Thank you.
Thank u sir
This just saved my ass ...I just did this to my 03 blazer ...my heater core clogged and had my engine over heating so I just bypass the core in order to get to work ...its -15 here right now ...I had to drive to work for a week with no heat .....saw this video went to get the hf pump and menards for some hose and clr ...hooked it all up tryed pumping the reverse of how coolant flows ...it really didn't flow much but when I switched directions it shot water everywhere lol ....flushed her about 3-4 times until water was totally clear put new heater hoses on and man this heats blowing great ...thank god ...💪🏽💪🏽💪🏽
That’s some MacGyver stuff right there. Great job man, never seen that trick! 👍🏻
Elite Earthworks LLC, I sometimes come up with some strange ideas. Lol. Thanks for watching! 🙂👍
To The Top Crane well looks like it worked well!
@@eliteearthworksllc, it definitely did! I think you could bake a cake in that car now. The heat is so hot that it's uncomfortable to leave a hand in front of the vents.
To The Top Crane nice! Going to need it
@@eliteearthworksllc, I know. It's getting cold. 😔
Hey now that is a great idea 💡!
Would not work for my old pickup tho.......... because all of the water would run out in the floorboard, hole in the heater core ! 😊
I can get by without a heater so I just bypassed it........ really because I don't want to tear out the whole dash ! 😆
Thanks for sharing and take care. 👍
Ken Gamble, a hole in a heater core is no good. Heat is a necessity here during the winter. I don't blame you for not wanting to tear out the dash. That can be a daunting task in today's vehicles. Thanks for watching! 🙂👍
To The Top Crane adding flex seal to the mix would help the holes!
@@richardsavaglio661, LOL! I'm sure the cooling system would be less than appreciative of flex seal. 😂. Thanks for watching! 🙂👍
Sometimes Harbor Freight surprises the heck out of me. Every so often you get a bit of kit from them that'll just last forever, or they'll include random spare parts that one of the major companies would happily have charged you an extra 50 or 100 bucks for.
Sandy, I agree. It's like a roll of the dice anytime a purchase is made there. I've heard good things about their Vulcan line of welders though. So, maybe they are stepping up their game. Thanks for watching! 🙂👍
I've never used a pump, nor chemicals. (I think that would be the more permanent fix, short of heater core replacement). I always just removed both hoses from the core, and used the ol garden hose nozzel. Spray one way, then reverse. Repeat until clean. You can see the crap being forced out.
neb4x4, I did the garden hose trick last winter. It didn't work nearly as well. The heat is so hot now, it's uncomfortable to keep a hand in front of the vents. Thanks for watching! 🙂👍
Done this on lots of machines and all my old second Gen dodges works great
Rouge Excavating, it worked much better than I anticipated. Thanks for watching! 🙂👍
glad you put this up, I am working on a ford explorer that has a similar problem with the heat.
hope I can get it going good again.
J. Chris Beck, hope you get it going. If I can help in any way, let me know. Thanks for watching! 🙂👍
Damn when he said 16 yo with no muffler on the civic. I felt that .... 26 and still that guy😁
You probably dont care but if you're stoned like me during the covid times you can stream all of the latest movies and series on instaflixxer. Been watching with my girlfriend during the lockdown =)
@Chad Leighton Yup, I've been watching on InstaFlixxer for months myself :D
I wish I knew this trick 10 years ago. The wife's Dodge van heater core clogged up and I kept flushing it with water also reversed the heater hoses every couple months. Must be a Dodge and Jeep thing.
D Master, it must be. If you encounter the problem again, this method really worked well. Thanks for watching! 🙂👍
Great little tutorial there Jimmy, don't know if I will need it, my vehicle is a Toyota Hilux Dual cab I think it's called a Tacoma the year is 2008 in the USA.
barry hansen, hopefully you don't need to use it. Heater core issues are no fun. Randy over a G4 Outdoors, drives a Tacoma as well. Thanks for watching! 🙂👍
@@ToTheTopCrane his will not have only 56,600 km on the clock though. that train I mention was roughly 50,000 tons metric they just re-opened the line, was going 92klm an hour when deliberate de-railed.
barry hansen hiluxs are cooler than Tacomas, way tougher. We can’t get hiluxs in the US because of a stupid thing called the moose test.... government BS crash avoidance testing. Tacomas are as close as we can get but there not the same chassis and we can only get limited off road features compared too you.
You may need the extra impeller. I used similar pump to empty pontoons on my dock and the rust chewed it up pretty good. I got lucky by turning impeller over to keep using it. Now I keep the spare impeller with the pump not in the spare parts box in the garage. You might also check to see if the hoses collapsed internally, that is a common problem.
Bill Whalen, I have the spare parts in my tool box with the pump. I doubt I'll use that pump for anything else. I suppose time will tell. Thanks for the tip and for watching! 🙂👍
Nice that the pump has a rebuild kit. Many of the hard to fart tools have no spare parts. Just throw away.
A cliffhanger! Standing by. Thanks for the video.
Duncan MacKenzie, I won't keep everyone in suspense too long. Lol. Thanks for watching! 🙂👍
Lol I like it " 😂 built the car around it"
Greetings from So FLA Jimmy! 👋 I’ll have to check and see if my Dodge even has a heater. I don’t remember ordering that ad-on option when I bought the truck! 😅
Loved the video anyway! It’s good to mix it up here and there! 🤜🤛
psidvicious, I wish I didn't need a heater. I suppose if I moved down there, I wouldn't need one. But, you'd try to get me on a surfboard. So, I'll stay here. Lol. Thanks for watching! 🙂👍
Hahaha!😂
🎵Lets go surfin’ now
everybody’s learnin’ how🎶
2004 Jeep Liberty here. OPE!! No heat unless I am driving and RPM's are up there much above idle. Can't warm the car up and then hit the Minnesota roads without my snow mobile suit once it is single digits or below zero. Once I have been driving for 10-15 and RPM's are above idle the heat finally kicks on and it will eventually get REALLY toasty until I get back to a longer idle (like sitting in the Hard To Fart parking lot going over my list)😂 Do you think next time I am in Hard To Fart I should grab a pump? Also does the 50-50 CLR/Hot water mix just keep cycling in/out of the bucket over and over and then you just reverse the 2 hoses at the heater core on the firewall?How long do you run it each way. THANK YOU!!
What size is the 10ft of heater hose? 3/4 inch? Do I need a foot valve. 2002 Jeep with no heat. Thanks!
A foot valve would be optional. If I remember correctly, I used ¾ inch heater hose. It's been a while since I made that video.
That a fact crane man you told the truth on how its made!
Very cool video great how to!
Cut and Clean TV, thanks Andy! I'm hoping it helps one of my subs who is having trouble with heat in his semi. We think his heater core is plugged. Thanks for watching! 🙂👍
Ummm...Why isn't your kiddo helping? She will need your knowledge some day. Thanks for sharing a cool tip!
Wayne Tharp, she was out running errands and hanging out with Mrs. Top Crane. I try to pass on what I can to my kiddos. Some of the stuff I do, they have zero interest in though. Thanks for watching! 🙂👍
@@ToTheTopCrane She will always have UA-cam for a reference later.😉 My daughter never liked getting her hands dirty but always likes to hang out and grab tools from a pretty early age.
How much was the little pump? Bought some clr but wasn't planning on using a pump until I watched your video!!
mike mancusi, the little pump was $58. It worked really well on this heater core. Thanks for watching! 🙂👍
Let me know how that CLR turned out got the same problem in My Expedition thanks.
Robert Bradford, it worked very well. The heat from the vents is now hot enough that it's uncomfortable to keep your hand in front of it. Thanks for watching! 🙂👍
Sorry was it clogged from the outside, dealership is quoting me 3100 because he said the heater core is clogged from outside , I wonder if this method will work for.me
Find another place i dont know what he means clogged drom outside he scaming you
Hey I know this video is 2 years old but how is the heat today? I been battling reverse flushing my heater core in my 08 liberty for awhile now. I’m not going to pull the seats, dash, steering wheel off for the core or pay someone 2k to do it , also any worries of the clr eating away the aluminum in the core ? anyway thanks!
Heat still works like a champ!
Good video, I'll never own a jeep product again.had a jeep compass and lost big time.
What is that a bypass you have pinched off there?
CLR will damage aluminum, just use water, or radiator flush which is safe for aluminum.
Thanks it’s works
I'm going to try it what am I out price of the pump vs new core
John Warren, the pump was $58. I was willing to spend a little in the hopes that it would work. As opposed to removing the entire dash to get the heater core out. If you try this, I hope it takes care of the problem. Thanks for watching! 🙂👍
Glad to know it worked Jimmy
Craig Nicholson, sorry for the delayed response. It worked very well. Thanks for watching! 🙂👍
@@ToTheTopCrane Jimmy no working family man can respond right away am just happy to comment with out a reply sir
I need to do that to my heater core in my JK.
You are wrong about the heater core being placed on a stand and the car being built around it. The heater core and windshield wiper assembly are actually hung on fishing line, and then the car is built around them both.
dp pmm, LOL! That seems about right! It's amazing how buried some of this stuff is in vehicles now. Welcome to the channel, and thanks for watching! 🙂👍
turkylips333 wow. Too bad you can’t watch a video on how to get a joke or where to find a sense of humor.
Thats brilliant
Read through the comments, looks like it worked
Lawn Commander, how are you doing? It did indeed work. Hope you are doing well. Thanks for watching! 🙂👍
I have the same problem I have heat for a few seconds then I have to turn it off and wait few minutes to get warm air again lol. I just don't drive it in the winter lol. I took it to get it flush but the mechanic said it's not the heater core like and idiot after I had it towed home. I said flush it not diagnose it because the blend door isn't working however I have it on the heat side so that's not the darn problem. It's a car and the heater core hoses are a nightmare to get to without dissecting the top of the motor. I told him after I got it back and he said to send it back and he would flush it but I was kinda mad paying to have it towed there and back plus his fee for whatever he did I told him to piss off lol.
Link to that pump
Just so you know, CLR is acidic. That's what makes it do what it does. If you use anything like that to clean your Core out, you're gonna want to make sure you flush it all out thoroughly with hot water.
I’m glad your daughter will be warm again.
walter mattson, she is very glad too. Lol. I'm hoping this helps John Warren with the heat in his semi. We had a lengthy conversation about it during the livestream last night. Thanks for watching! 🙂👍
Jimmy my sisters did the same thing had to change core not fun itll drive u to drinken lol tks gary ps hole dash comes out just like my 2500 d/c
Gary Johnson, I think every vehicle should have an access panel for the heater core. Lol. Thanks for watching! 🙂👍
Will a sump pump work in a bucket?
It might. But, I would install a tee with a valve on the output of the pump. That way you can regulate the pressure. A pressure gauge would probably be a good idea too. Most heater cores are designed to work at 15psi or less. You don't want to rupture the heater core.
Thanks , the core is clogged with I believe is a stop leak product . Does CLR help with this
@@richardbrewin4165 I'm not sure.
You never ran CLR through the radiator???
The radiator was only a month or so old.
@@ToTheTopCrane imma take that as a no then
No. I didn't run it through the radiator. Sorry I didn't explain very well. The heater core was almost plugged. Flushing it like this worked very well. Before flushing it, the heat at the vents was only about 70 degrees. After, it was 135-140.
Great video. Wish you would have told us the results.
Frankenstein rules, I'm not sure what happened to the after footage. But, I can tell you that the heater works very good now. Thanks for watching! 🙂👍
Foot valve - mandatory or optional?
Optional
That’s the best type of foot valve! Giving this a shot today on my XJ.
@@frankj2458 it worked very well on my daughters car. Hope you have the same success.
Well, the flush worked great. Lots of rust and now the input hose to the heater core is scorching hot. Unfortunately, I’m still running down this heat issue. Last possibility is the vacuum system. I can verify this treatment works great though!
Glad it worked to flush it out. Thanks for the update. Hope you get the rest of the puzzle figured out. Thanks for watching and for the feedback. 🙂
Your video was like watching some D grade movie and then all of sudden THE END without any conclusive end to it... HAHAHAHAHA!!!!!!
How much did it cost you to watch it? Nothing? I'd say you broke even at the least.
wow!
Sooooo,,,,,,,, Do I need to make an appointment?
G4 Outdoors, do you need your heaters core cleaned? You don't need an appointment. Just let me know when you will be here. Thanks for watching! 🙂👍
Nice trick! ....13
arkansas13, thank you! As always, thanks for watching! 🙂👍
Where dud u get the pump thats cool
Gary Johnson, I got it from Harbor Freight.
HF, Hard to Fart
Didn't work??
Why even bother doing a video without showing if t worked? People facing this problem don't know if they should do what u did. If you can't show it actually worked. I guess u may have sold some little pumps. From harbor fart.
MS Bonz, my after footage got messed up and I couldn't recover it. So, it is what it is. But, it worked amazingly well, and the heat is still going strong. Thanks for watching! 🙂👍
@@ToTheTopCrane thank you for clarifying that, i appreciate that. I'm sorry if i offended you, i m frustrated with one I'm dealing with. I was vey interested in what u where doing. I thoght it was genuis to use a pump. But there was no discovery if it worked. From what i searched for and didnt see u leave a message here to say it worked. I assumed it didn't work. We used hot boiling water with the Iron out solution which is just like CLR it cleaned a lot of junk out and it brought heat but those flip doors arn't sealing so we are gonna have to tear it down. To change it all. Well thank you for your response and the idea of using CLR . THE PUMP IDEA IS GREAT. Ill get one another time. Since its costing a lot to fix it. Anyways i apologise for having a smart butt attitude. 😩😩😩😩 please forgive me.😑😑
@@msbonz4145, no offense taken. 🙂. Hope you get yours working. If I can help in anyway, feel free to reach out to me. 🙂👍
Chinesium 😂
@DICKERED WITH DAVE, you Sir, are correct. 🙂👍
Kevin Smith, I can't take credit for for it. That is an AvE word. Thanks for watching! 🙂👍
Too much talk and don't go 2 the point
Where do I get the pump from???
