• Q: How to replace the Heater Core on 2002 Buick Park Avenue?

  A: Draining the cooling system stands as the first task when replacing a heater core. The Hose Clamp Pliers (J 38185) enable users to disconnect the heater hose clamps before separating the heater hoses from the heater core. Start by removing the console assembly combined with the auxiliary air distribution duct from the system. The HVAC module assembly requires removal of its heater core heat shield cover followed by the air filter access cover. Begin the core replacement by unscrewing the heater core cover screws so you can expose the heater core through releasing the cover downward. Start by taking off the retaining screws and straps from the heater core and extract the heater core. The new heater core installation begins with inserting the core into the HVAC module while using the retaining straps and screws to fasten it securely at 1.5 N.m (18 lb in). Relock the heater core cover by tightening its attachment screws to 1.4 N.m (12 lb in). After fixing the air filter access cover screws at 1.4 N.m (12 lb in), install the heater core heat shield cover. Complete the installation sequence with the auxiliary air distribution duct and console assembly. Complete the heating system connection process using Hose Clamp Pliers J 38185 before filling the cooling system.
