Did this video help you?

PATSNATION: My problem is when car running fogs up the front glass,when car stops you can see fogging begining again center ac vent, will a flush take car of it? Do i need a new heater core?

Rob Christianson: Hey there, had a question... because I know my mechanic told me replacing the heater core was $600+ cuz of pulling the whole dash apart, I appreciate this video because he charged me $40 each time he flushed mine. Sad thing is, its not really working b/c the previous owner of my 08 Liberty used stop leak liquid glass and plugged up the heater core BAD. He said he got some gunk flushed out but prob only 5% of the problem. 

Before I shell out $600+ for him to tear the dash apart to get to the heater core, I might try it again myself. My question: Is it okay to run Rubbing Alcohol through the core first?  (The reason I ask is that my son works at a phone store and said they use alcohol to remove liquid glass on phone screens. maybe I can put a few bottles of that stuff through it pretty cheaply and then flush with water? Your thoughts?

Marcus Taber: Thanks man, exactly what I was looking for.

Glazier: Hey Scouter, I just bought a 2002 liberty a few months ago. Now that the cold weather is apon us here in Baltimore, I have very little heat. Just wanted to say thanks for the video Scouter. I'm going to give it a shot. I'm in Rosedale, if I have any problems I give you a holler. Lol 😲 HELP!!!!

Robert Williams: Just wanted to say thanks for the video! Going to be flushing my heater core this weekend along with a thermostat change. Let me know how that blender door goes! May have to do that as well!

RLB Entertainment: i just tried that today and it didnt work, topped it off with fluid still no heat only luke warm or cold. when i go fast on highway it comes out hot but just sitting still or driving in town it dont. could my heat core just be bad? what other reasons could cause it to do that. car dont overheat or anything. i have 03 jeep liberty as well just want my heat to work again its cold!

Nina Nearhoff: DeathScouter - Thank you so, so much for your help and video.  My 16 year daughter had no heat coming out of her heater.  I did exactly as you directed and IT WORKED AWESOME!!!  You saved (this single mother) tons of money and provided my little girl with heat.  I can not thank you enough for taking the time and effort to help out with your video....  Your efforts are noticed and so, so greatly appreciated.  It's kind souls like you taking the time to make these types of videos that help out people like me how so note mechanically enkindled.   THANK YOU!!!! : )

Brian Bell: Great video! Just finished this on a 2002 liberty. Thanks for the help!

Odin Runes: You should only put distilled water in the coolant system. If you do not. You will cause corrosion through your whole coolant system.

Exzir: Flushing heater cores is awesome to do even when you don't have a problem. If your not getting heat this,is,your first and easiest fix. 2nd would be to check your thermostat and see if it is stuck open.

Vicarious Fan: got a similar problem in my Jeep Liberty, no heat coming out, however now my engine overheats after a few miles. The heat some times come on for a few seconds but then goes away.

Any ideas?

S.david S: Hello So Wich hose is the inlet and outlet Kind of confuse Help ?

Jarod Luba: This video helped me do the job. I should have done this first! I spent money and put in a new thermostat, which solved the problem a couple years ago but not this time. The flush had heat flowing! Much needed in the Kansas City cold weather. Thanks for posting.

Omar Flores: hello i live i a bulding so we don't have any water near the street , can i just pump air with a compresor to clean the heater core? thank you

Hossam Messiha: Thanx so much man, they wanted to charge me 800$ to replace the heater core , what a rip off

Annony Mouse: I'm not getting heat either but the RPM doesn't seem to matter, no heat at any speed.  Is this the heater core possibly or could the thermostat have something to do with my lack of heat?

kevswick: Did you have to leave the fresh water hose lying on the ground just running away? Waste of precious water drives me crazy!

Pete Riley: Gret video.  I was going to go to the mechanic.  This will work!

Josh Hodges: Now after I do this, do I need to flush the air out of the system? And how do I do that
