Four Seasons HVAC Heater Core P/N:92003
Warm the cabin and feed the defrost vents with the FOUR SEASONS heater core (MPN 92352), an aluminum heat exchanger built as a direct-fit replacement for a wide range of GM sedans — including the Buick LeSabre, Cadillac DeVille, Oldsmobile 98 and Pontiac Bonneville. See the Buyer's Guide tab for the full application list.
This core is the tube-and-fin unit that hot engine coolant flows through; the blower motor pushes cabin air across its fins to warm the interior and supply the windshield defrost path. If a leaking or clogged core is the cause of weak heat, a sweet coolant smell, or fog on the inside of the glass, this replaces it. It's a popular Buick Lesabre heater core replacement, and installation follows the factory removal procedure for your vehicle.
