• Q: How to replace the Heater Core on 2004 Buick Park Avenue?

  A: As a first step for heater core replacement one must drain the cooling system. The Hose Clamp Pliers from J 38185 tool will be used for loosening clamp fasteners before disconnecting the hoses from the heater core. The first step is to remove the console assembly and after that you should detach the auxiliary air distribution duct. First detach the heater core heat shield cover that belongs to the HVAC module assembly then remove the air filter access cover. Start by removing the screws from the heater core cover then carefully let the cover down to reach the heater core for removal. Rephrase the sentence as follows: Uninstall first the retaining screws along with straps that secure the heater core before removing it. The HVAC module demands attachment of the new heater core through retaining straps and screws followed by screw torque adjustment to 1.5 N.m (18 lb in). Tighten the securing screws of the heater core cover to 1.4 N.m (12 lb in). Begin by attaching the air filter access cover through its screws while tightening them to 1.4 N.m (12 lb in). Afterward install the heater core heat shield cover while moving to the auxiliary air distribution duct and console assembly. The Hose Clamp Pliers (J 38185) will be used to reconnect the heater hoses while filling the cooling system.
