Four Seasons HVAC Heater Core P/N:98553

Help keep warm air flowing to the cabin and defroster with the Four Seasons heater core, part number 98553, an aluminum heater core that serves as the front heater in the vehicle's HVAC system. It fits many vehicles, among them the 1987-1991 Chevrolet Suburban, 1983-1990 Chevrolet P60 and 1983-1990 GMC P6000.

Hot engine coolant circulates through the heater core while the blower pushes air across it, sending heat to the passenger compartment and the windshield defroster. Four Seasons has more than 50 years of mobile A/C experience and engineers and tests its products with years of trouble-free operation in mind.

• Aluminum heater core: an aluminum unit for the front heater position.
• Heavy-duty construction: built for product durability.
• O.E. fit, form and function: quality engineering intended to match the original part.

Signs this part may need replacing include weak or no cabin heat, a sweet coolant odor inside the vehicle, fogged glass, damp floor carpet or unexplained coolant loss. Diagnose the cause before replacing it, because a faulty thermostat, a blend door problem or another cooling-system issue can produce similar symptoms.
