• Q: How to replace the Heater Core on 2005 Buick LeSabre?

  A: The replacement process for Heater Core starts by first draining the cooling system and then removing the fuel injector sight shield. The hose clamp pliers type j 38185 should be used for heater hose clamp removal until the heater hoses separate from the Heater Core. Inspect the Heater Core assembly by removing the air distributor duct screws beginning with left and right screw positions 1 and 2 yet leave out the right side screw installation. The next task involves taking out all screws from the air distributor duct and Heater Core heat shield before removing the heat shield itself. The installation of a new Heater Core begins by removing the Heater Core cover screws followed by covering detachment and then removing the retaining screw with strap before extractor the Heater Core from its placement. The hvac module installation requires users to fit the new Heater Core into position using attaching straps and screws and tightening these components to 1.4 n.m (12 lb in). Fit the Heater Core cover by positioning its front dash seals properly and secure the screws tightly at 1.4 n.m (12 lb in). Install the Heater Core heat shield with its screws and apply torque to 1.4 n.m (12 lb in). Secure the air distributor duct with special attention paid to properly seating and tightening the left side screw to 1.4 n.m (12 lb in). To finish the installation process attach the left and right sound insulators along with heater hoses which require the hose clamp pliers (J 38185), the fuel injector sight shield, and complete the cooling system fill.
