89 Cavalier heater core replacement

My cavalier needs a new heater core. Do I have to pull the entire dash to replace it.

Re: 89 Cavalier heater core replacement

The dash board does not need to be removed.

Some trim covers and the glove box need to come out and some A/C duct-work, then you sneak the heater core out very carefully.

The complete removal procedure is listed below.

Disconnect battery ground cable and drain cooling system.

Raise and support vehicle.

Remove rear lateral transaxle strut and mount, if equipped.

Disconnect heater case drain tube, then disconnect heater core heater hoses.

Lower vehicle and remove right and left hush panels, steering column trim cover and glove compartment.

Remove heater duct retaining screw and heater duct.

Remove heater core cover attaching screws, then gently pull cover rearward and out of vehicle, when removing heater core assembly, pull assembly straight toward interior of vehicle until plastic drain tube clears cowl. If assembly is tilted in any direction before tube clears cowl, the drain tube may break.

Remove heater core retaining clamps and heater core from case.

Reverse procedure to install
