Keep warm coolant flowing to your dashboard vents with the Four Seasons heater core 98501, an aluminum HVAC heater core that transfers heat from the engine's coolant into the air pushed through the cabin. It's a direct-fit replacement for a wide list of GM full-size cars, including the 1977-1985 Chevrolet Impala, 1977-1990 Chevrolet Caprice, 1977-1990 Buick LeSabre, 1977-1989 Buick Electra, 1977-1984 Cadillac DeVille, 1977-1986 Cadillac Fleetwood, 1977-1984 Oldsmobile 98 and 1977-1986 Pontiac Parisienne — see the Buyer's Guide tab for the full 34-application list.
Built by Four Seasons, drawing on decades of mobile A/C and heating experience:
- Heavy-duty construction for lasting durability.
- Quality engineering for O.E. fit, form and function.
- Independently tested for proven quality and performance.
If a leaking or clogged original heater core is behind weak cabin heat, a sweet coolant smell, interior fogging, or coolant on the floor, this aluminum unit replaces it. Because it plumbs into the cooling system, plan on draining and refilling the coolant during installation. Signs the original may need replacing include those coolant leaks, foggy windows and cool-only vent air even when the engine is at full operating temperature.
