EBSCO Auto Repair Reference Center REMOVAL & INSTALLATION Disconnect the negative battery cable. Position a drain pan under the radiator, open the drain cock and drain the cooling system to a level below the heater core. NOTE: Plug the heater core tubes to avoid spilling coolant in the passenger compartment during removal. Disconnect the heater-to-engine coolant hoses from the core tubes on the fire wall, in the engine compartment. NOTE: On some early model vehicles, the cabin light mounted under the dash may interfere with cover removal. If necessary, loosen the retaining bolt and reposition the light housing with the wiring attached. From the passenger compartment (under the dash) remove the heater core rear case cover-to-cowl screws, then remove the cover from the vehicle. NOTE: On a few of the early model vehicles covered by this manual, some of the heater core cover screws may be partially/fully covered by the dashboard. Be sure that all are removed before attempting to remove the cover. If necessary, unbolt and reposition all/part of the dashboard for better access. Remove the straps or brackets from each end of the heater core. Carefully remove the heater core from the cowl and case. Installation is the reveres of removal. Run the engine at normal operating temperatures and check for leaks. EBSCO Auto Repair Reference Center
