• Q: How to replace the Heater Core on 2000 Buick Park Avenue?

  A: Draining the cooling system should be the first step for heater core replacement. You should employ the Hose Clamp Remover/Installer (J 37097-A) to disengage the heater hose clamps which enables separation of the heater hoses from the heater core. Start by disconnecting the console assembly together with the auxiliary air distribution duct and heater core heat shield cover from the HVAC module. You must first disconnect both the heater core cover screws and the air filter access cover. Lower the components while moving them aside for sufficient heater core access. First you must detach the retaining screws and straps from the heater core before extracting it. You should place the new heater core into the HVAC module and fasten it with retaining straps and screws while using a torque of 1.5 N.m (18 lb in). When reinstalling proceed by tightening the heater core cover screws and retaining the specified 1.4 N.m (12 lb in) torque value before cranking the air filter access cover screws to 1.4 N.m (12 lb in) torque value. To complete the installation process you must fasten the heater core heat shield cover, auxiliary air distribution duct and console assembly before applying the Hose Clamp Remover/Installer (J 37097-A) tool to secure the heater hoses before conducting a cooling system refill.
