Keep warm air moving through the dash vents with the FOUR SEASONS heater core, part number 90053. This aluminum hvac heater core is a direct-fit replacement for the listed 2000-2005 Buick LeSabre, 2000-2005 Pontiac Bonneville, 2001-2003 Buick Olds Aurora and 2001-2003 Oldsmobile Aurora. Mounted inside the HVAC case, it routes engine coolant through its aluminum core so the blower motor can pass cabin air across the hot fins for heat and defrost.
- Aluminum core: transfers coolant heat to the incoming cabin air.
- Heavy-duty construction: built for long-term durability.
- O.E. fit, form and function: engineered to match the original unit on the listed applications.
- Independently tested for proven quality and performance, backed by over 50 years of Four Seasons mobile A/C experience.
Weak or no heat, a sweet coolant odor, fog on the inside of the windshield, or unexplained coolant loss are common signs a heater core may be leaking or clogged. If a failed heater core is the cause, this unit replaces it. Confirm your engine and options on the Buyer's Guide tab before ordering.
