Did this video help you?

DeathScouter: Flushing the core and topping off the fluid DID fix the immediate problem. However, Jeeps are NOTORIOUS for losing heat as a result of the "air mixture doors" breaking on the INSIDE of the vent system. These are the doors that open & close when you move the temperature knob on the dashboard and allow/disallow air to flow over the heater core (or not) and route cold/hot air into the vents. There are 2 doors (1 over the other) that tend to break in the middle of the hinge. These JUST broke (Dec 2013) so I'll be doing a video on fixing these soon.

Jignesh Rathod: Thanks. Great job with explanation and video shooting while clamping the hoses on :)

Javi Tait: What if my jeep only gets solid heat at 40° and up????

James Beasley: I flushed my heater core on my jeep liberty and now I have heater again.This saved me a couple hundred dollars😂😂😂Thanks Google!!!

Ricky Ricardo: Wish it was that easy to replace the heater core, mines pumping evaporated coolant into the cab haha. Is there a way to do it without taking the whole dash out? HELP PLEASE.

John Long: I just wanted to say THANK YOU! I am in Minneapolis Minnesota with my newborn son and girlfriend. I live in Cincinnati Ohio and needed to get home for thanksgiving. And.......My car wouldn't get heat. I watched your video and followed the steps (finished at 3a.m.-in 10° blistering cold) and will now be able to go home in time, THANKS A MILLION!!!

Napalm The Scortcha: Can A Clogged Heater Core Cause your car to run hot or over heat??? Thanks

Brundon: thanks

Brad Fahey: Did it fix it?

jagerman06: I'm with Brad, did it work? My heat had same problem, so I'm assuming from the disgusting coolant flush I just went through

BKofficer23: Did you drain the reservoir before detaching it?

torres34690: i look forward for front brake disc and the rear drum brakes..not to mention adjusting parking brake cable.. change the thermostat as well.

torres34690: nice commentary.

DeathScouter: No, I didn't drain it, but probably should have. Actually, my coolant was really low or else it would have dawned on me to capture it.
