To replace the heater core on a 1972 Buick Skylark, first disconnect the battery and drain the cooling system. Remove the dashboard and the heater assembly from the vehicle to access the heater core. Unclamp and disconnect the old heater core from the heater box, then install the new core and reassemble everything in reverse order. Finally, refill the cooling system and check for leaks.
