Four Seasons HVAC Heater Core P/N:98531

Restore cabin heat in your classic GM with the FOUR SEASONS heater core (P/N 98531), an aluminum core that circulates hot engine coolant so the blower can warm the air entering the passenger compartment. Built for O.E. fit, form and function, it drops into a broad range of 1963-1968 full-size and mid-size GM cars, including the Chevrolet Impala (1964-1968), Bel Air and Biscayne (1963-1968), Chevelle and El Camino (1964-1967) and Caprice (1966-1968), the Pontiac GTO and Tempest (1964-1967) and LeMans (1965-1967), the Oldsmobile Cutlass and F85 (1964-1967), and the Buick Skylark and Special (1964-1967) — see the Buyer's Guide tab for the full list.

Whether you're hunting a Chevrolet Impala heater core or reviving another mid-'60s GM, this unit handles the heater side of the climate system.

• Aluminum core: lightweight heat exchanger that transfers coolant heat to the cabin airflow.
• Heavy-duty construction: built for durability.
• O.E. fit, form and function: quality-engineered to match the original.
• Independently tested: for proven quality and performance.

Backed by Four Seasons' 50-plus years of mobile A/C experience. If a leaking or clogged heater core is the cause of no cabin heat, fog on the inside of the windshield, or a sweet coolant smell, this replaces it. For engine specifics, refer to the Buyer's Guide tab.
