Buick Heater Core Parts and Q&A
- Q: How to Service and Repair the Heater Core on Buick LaCrosse?A:One must drain the coolant as the first step of heater core replacement. The Hose Clamp Pliers (J 38185) should be used to set aside clamps of the heater hose inlet and outlet before disconnecting the hookup between the heater core and hoses. The first step involves removing RH and LH instrument panel closeout/insulator panels together with floor carpet and communication interface module. Use Hose Clamp Pliers (J 38185) to transition the floor air outlet duct away from the floor reinforcement holes before cutting it free from the heater core outlet cover. To proceed you should remove the heater core outlet cover screws with heat stakes using a small chisel before taking off the outlet cover from the HVAC module assembly. First prepare the heater core cover by removing screws and heat stakes with a small chisel then take off the cover from the HVAC module assembly. Move the heater core as well as its foam seal outside the HVAC module assembly. The installation process requires addition of a new heater core foam seal to the HVAC module assembly before heater core installation. Install the heater core cover by drilling the dimples around its heat stakes using a 5.5 mm (7/32 in) drill bit and then tighten its screws to 1.5 N.m (13 lb in). Reuse the procedure to install the heater core outlet cover screws by tightening them to 1.5 N.m torque (13 lb in.). The rear air duct should be reattached from the heater core outlet to the floor reinforcement holes where it will be installed. The technician reattaches the communication interface module followed by the floor carpet and insulator panels for both sides of the instrument panel. You should link heater core inlet and outlet hoses and tighten their clamps with Hose Clamp Pliers (J 38185) before performing coolant refill.
- Q: How to Address Issues with the Heater Core on Buick Regal?A:The first step to replace a Heater Core involves taking off the fuel injector sight shield along with draining coolant from the system. You need to detach both heater hoses from the Heater Core while also removing the lower floor console when present and then walking down the lh and rh instrument panel insulators. The outlet cover must be moved downward and to the rear from the duct assembly before you can remove its screws and the outlet assembly. You will now detach the Heater Core cover by unfastening its screws while removing the cover along with seats (1, 2, 3) and Heater Core outer seal. First remove the Heater Core line clamp screw followed by its retaining clamp before moving on to the Heater Core pipe retainer clamp screw . Remove the Heater Core from its position inside the hvac lower case after discarding all seals consisting of the lower seal and center seal and upper seal and side seals. Insert the new side seals and upper seal along with the center seal and lower seal onto the hvac case before inserting the Heater Core. The installation requires a screw to fasten the Heater Core line clamp at 1.5 n.m (13 lb in) while the Heater Core mounting clip requires another screw with a proper 1.5 n.m (13 lb in) torque setting. Position the Heater Core outer seal to the Heater Core and afterward install new seals (1, 2, 3) onto the Heater Core cover. Secure the cover with its screws to 1.5 n.m (13 lb in) torque specification. Place both Heater Core outlet cover screws and tighten them to 1.5 n.m (13 lb in). Completing the service requires lower floor console installation if present together with lh and rh instrument panel insulators reinstallation followed by connecting the heater hoses to the Heater Core before refilling the coolant system and installing the fuel injector sight shield.
