I have a 2001 GMC Jimmy I have to replace the heater core, but I cannot get the housing out. I already took out the dash and now the housing wont come out. Am I missing another screw that goes to the housing?

    I chiseled the stacks that were on the bottom of the housing, but it feels like theres a screw on the top right side of the housing. Only the top right side does not want to budge so of theres a screw there I cant get to it

You have to chisel them stacks off. Then unscrew the six screws holding the housing together. When closing the housing up you first need to take a drill and drill a 7/16 hole where the stacks were and put new heater core screws in there.

    Make sure to chisel them real good. Have you removed the hoses from the heater core yet? Go under the hood and unscrew the clamps off the heater core stems. Should be a 5/16 socket or you can use a nut driver. Sometimes them hoses are stuck real good from heating and cooling so much. I use a pair of needle nose vice grips and clamp them on tight enough to grab the hose (not so tight as to break the stem) and rotate it back and forth and this will break the seal and then they can be pulled off.

    There is a metal piece molded into the tabs for the bolts but this will allow you to bend the unit towards you to remove the heater core

    Did you remove the stud located behind the blower motor resistor?

    Let me do this. If the last this you did was remove the "dash." Here are the next step to follow step by step. You tell me where you are in therm.

    Remove:
    - Air inlet assemble if there is one on your vehicle.
    - Vacume Hoses
    - Heater Assembly Studs
    - Blower Motor Resistor
    - The Stud inside the case for the heater assembly which will be located behind the blower motor resistor.
    - Heater Assembly Chassis Screws
    - Remove the heater assembly now.
    - Access cover screws and the cover from the heater assembly
    - Heater Core from the heater case assembly.

I have a 2001 Jimmy. back in Sept the heat just blew out cold air I took it in and they did a Antifreeze Reverse Flush Heater core and about a month ago it stopped working agian. Its - 28 and Im freezing...


WEll, it is unlikely that the heater core plugged up again, moe likely you are low on coolant. There are also water valves and heater doors that can cause what you describe.

You do need to be makeing enough temperature, check that the thermostat is allowing you to get warm enough.

My heater will only blow out of the dash vents and won't move to floor or defrosters. Many have said to change the vacuum hoses. Can anybody tell me where to find them? Do I need to take apart the dash?


Heater flap works on vacum lines. My jimmy had same problem. Found out flap broke inside heater core. Gmc had a default. If something breaks it goes to defrost as safety precaution. Or a vacum leak in a hose to heater.

How do you remove a heater core from a 2000 GMC JImmy


2000 GMC Jimmy heater core replacement in order to replace a heater core in a 2000 gmc jimmy the coolant must be completely drained and the entire dash including radio, vents and panel covers must be removed. four screws hold the top portion(closest to the windshield) in place. they can be found under the windshield defrost vent. after the entire dash is removed a safety harness under the steering column must be removed and the steering column must be dropped to the driver seat. the heater core housing(black plastic) is located right center of the dash and is a two part housing one piece on top of the other. the housing is attached to the fire wall and must detached before replacement can continue. after detaching the housing from the fire wall separate the housing by unscrewing the six screws that hold it together. the heater core is now exposed. disconnect the heater core from the two hoses and discard. installation is the uninstall process in reverse. it is a very long and drawn out process that is not accomplished in just an hour or two . make sure you have most of the day or several afternoons to finish . Good luck and take pictures with your cell phone to use as reference.

Heater core replacement


You do not have to do anything with the air conditioning, its all inside car under right side of dash. 1. go under hood and unhook heater hoses and bracket( if equiped) from core tubes. 2. go under dash right side remove 13mm bolt far right under dash thats so you can pull dash out a little ways to get cover off heater where heater core is.3. 1/4 in. socket set and 1/4 in. socket take screws out holding cover on look close there is one hidden top far right can't remember how maney 5 or 6 i think, screws all out use a little finess and remove cover and there will be your heater core. Good luck.
