    Comments about CARQUEST Heater Core:

    The heater core was all aluminum, well made, functioned well. Installation in a 2003 Cadillac STS was not unreasonably difficult using the Factory Workshop Manual.

    The core used a separate metal bracket, since the aluminum end tank did not have the built-in attach points of the molded plastic end tank of the original factory core. The bracket caused slight interference with the molded plastic heater core cover. Two minutes work with a small saw blade in a Dremel removed the interference in the cover. Very minor problem.

    • Flimsy Mount Bracket
    • Reused Original Bracket

    Comments about CARQUEST Heater Core:

    Overall the install is easy with the right tools (hose clamp tool, hard to reach).
    The bracket that supports the back was flimsy, so I reused the original and it's much better. Really good value with discount code and store pick up.

        It worked well as a replacement. I'm getting good heat and haven't had any problems. It's to soon to tell how reliable this heater core is, but it appears to be adequate for the job at hand. At this writing, I am satisfied with the results of this repair.

        OE heater core had a"plastic" front and hose connections, when it failed my right foot was saturated with extremely hot coolant, and I suffered third degree burns that immobilized me for 3 months. Ready-Aire heater core is all metal, therefore stronger.

          Install was easier than expected. I liked the fact the end tank and nipples were made of aluminum rather than the plastic the original was made of.

            This is a replacement for my cracked heater core which was causing my rear passenger side floor to become completely wet. My boyfriend diagnosed and repaired the problem for me in no time. Heater core seems to made of quality material which I truly believe will last for a very long time.

              1992 Buick Park Ave, 4 dr. Where is my heater core located? Is it a complicated install?

                A:

                Hi Mike, glad to assist you! Here is the installation instructions: Disconnect the car's battery, removing the negative cable first and then the positive one. Raise the car's front end with a jack and support it on jack stands. Make sure the parking brake is applied. Drain the engine coolant into a large container using the petcock at the lower left corner of the radiator. Once all the coolant is drained there, drain the remnants at the engine block drain plugs. Disconnect the drain hose at the bottom end of the heater case and the heater hoses from the engine compartment firewall, loosening the hose clamps with a flat screwdriver. Unscrew and remove the right sound insulator from the bottom of the dash and the steering column's trim cover. Pry out the heater's outlet duct--it may take a trim stick--and then open, unscrew and remove the glove box. Remove the heater core cover, pulling it straight back so you don't break the drain tube. Remove the clamps for the heater core and remove the core from the housing. Insert the replacement heater hose into the housing with its clamps, then reconnect the heater core cover. Reconnect the glove box, heater duct, steering column cover and dashboard sound insulator. Connect the drain hose and heater hoses back to the core and heater case using their hose clamps. Lower the car off the jack stands. Fill the radiator with the engine coolant; use fresh water and coolant if the old coolant is contaminated. Reconnect the car battery starting with the positive cable.

                With reference to your inquiry on the Ready-Aire Heater Core - Part No. 398214, carefully remove the dash starting from the top and work down. Please take your time as it might need 3-4 hours or more depending on your skill. There is no need to remove the whole dash but just enough to get to the heater core which is behind the glove box on your 1990 Buick Lesabre. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
