Help bring warm air back to the cabin with the FOUR SEASONS heater core (P/N 91605), a copper replacement that fits the 1975-1980 International Scout II with all engines. A heater core is a compact heat exchanger that routes hot engine coolant through its tubes and fins so the blower motor can push warmed air across the dash vents and defroster.
Signs the original heater core may need replacing include weak or no cabin heat, a sweet coolant smell inside, fog on the windshield, damp carpet, or unexplained coolant loss. Because these symptoms can have other causes, diagnose the source before replacing. If a leaking or clogged heater core is the cause, this 1975-1980 International Scout II heater core is designed to replace it so coolant can again flow through the core and the heater can warm the cabin.
