How do you replace a heater core in an 84 Buick Park Avenue?

Answer 1

To replace the heater core in an 1984 Buick Park Avenue, start by disconnecting the battery and draining the coolant from the radiator. Remove the dashboard and associated components to access the heater core housing, then disconnect the heater core hoses from the engine compartment. Once unbolted, remove the old heater core and install the new one, reassembling everything in reverse order and refilling the cooling system with coolant. Finally, check for leaks and ensure proper operation before reinstalling the dashboard completely.
