if you have air conditioning you will need to take it to a garage and recover the r134, you will need to remove the dash to allow you to remove the heater box, it's an ugly job, I've done a dozen or so and can do it in about 6 hours now, the first time it was closer to 11 hrs, good luck

SOURCE: Removing the heater core from 2000 silverado

When I replaced the heater core on my 95 Suburban, I seem to remember having to disconnect the A/C lines on the firewall for the evaporator. There were also several nuts to remove on the engine firewall side from studs on the heater box that pass thru the firewall. It is definately a lot of work.

Good luck.

SOURCE: heater core 2002 jeep grand cher.

I purchased a Blen Door repair kit. for my 2002 Jeep Grand Cherokee after having only cold air blow out of the passenger side for over a year. I found it on EBay. It requires you remove the glove box, cut open the heater box and replace the blend door. I really didn't want to cut that open, however, with the tape that comes with it, I have had no problems with it leaking any air. The dual control no longer works, the temperature is now completely controlled by the drivers side, but to save $1200, I was willing to do this. I have taken the entire thing out before to replace the heater core, didn't want to do it again.

There is a black covering on passenger side that should have four screws in it. You should find the heater core hidden inside the casing.

Where is the heater core located on 99 Ford escort ZX2?


Typically you will find the heater core sits inside the dash just inside the fire wall of the engine compartment, from the engine bay you can follow the water lines from the cooling system and water pump that go back to the fire wall and through to the heater core, find those to hoses together and the heater core is on the other side under the dash, usually under passenger side under dash behind the heater box, they are usually labor intensive to pull, and some require pulling the dash partly off etc.

I have my dash off changing my heater core and i cant get figure out how to get the plastic mount the core sits in off!! what do i do?!


On the outside under the hood and along the fire wall..... There are about 5 nuts that must be taken off to allow the heater core and AC condenser box to be removed. You must remove the air filter box and associated hoses.... Then under that is a bracket which holds the ac accumulator (which also must be removed) Then these is the main computer on the fire wall on the on passenger side that needs to be removed to access all the nuts needed to be removed to let the heater/ac box loose from the fire wall. I am not a mechanic... I am an IT Computer guy that had just went through this process and it is HELL. Took me 2 days.

77 el camino leaks from passenger side behind dash. what could it be?


Hello there:
This leakage that youare seeing is coming from the heater core which means that you will need to remove the heater core and get a new one
The best way to do this is to Mark and disconnect the 2 hoses that are going thru the firewall to whick pipe they attach to on the heater core then remove the 6 or 8 nuts or bolts that hold it into place then you will find that the box that the heater core is sitting in may have some nuts and bolts on it to so remove them next the box itself needs to be seperated at the seam to assist in the removal of the heater core so cut along the seam with a very sharp knife or a utility knife and then remove the old heater core and install the new one then put everything back and dont forget to reseal the box otherwise you wont get much heat flow from the core de to air getting inside of the box ok then make sure you put sealant on the bolts where they go thru the fire wall and tighten it down firmly then reattach the hoses and you are done
Hope this is very helpful for you
Best regards Michael

How do you get to the heater core in a chevy s10 --I have removed the dash but can not get to the heater core


Passenger side bottom of heater box remove bolt. Engine side on fire wall behind distributor remove nut. Now, on top of evaporator box remove small plate with wires on it. Look inside, remove that bolt. The heater box will come out. There are only 2 bolts and 1 nut to hold box in place.

Heater core


NO, BUT THE COMPLETE HVAC MODULE NEEDS TO BE REMOVED. THIS IS BASICALLY THE LARGE BLACK AIR DISTRIBUTION BOX LOCATED UNDER THE RH SIDE OF DASH. THE RH BODY MOUNT BUSHINGS ARE ALSO GOING TO NEED REMOVAL & THE BODY SLIGHLTY RAISED TO GAIN ACCESS TO CORE UNDERHOOD.

Just pull the dash back a little by undoing all the bolts and screws, its going to be a tight fit find someone with small hands.

Remove the heater hose clamps and the hoses from the engine side of the firewall. From the inside under the dash on the pass. side, remove the lower panel screws and slowly pry the lower cover down and the heater core will slide out of the heater box. Installation is reverse of removal.
