Help restore warm cabin heat with the Agility Auto Parts HVAC Heater Core 9010221, a front heater core that drops in as a direct-fit replacement for the 1990-1996 Chevrolet Lumina APV, 1990-1996 Oldsmobile Silhouette, and 1990-1996 Pontiac Trans Sport. This front heater core routes engine coolant through its fin-and-tube core so the blower can transfer that heat into the passenger compartment for cabin warmth and windshield defrosting.
- Thermal performance & corrosion resistance: built with enhanced design features, including the latest fin-and-tube technology, for increased thermal performance and resistance to corrosion.
- Meets or exceeds OE specifications: a certified heater, fitment-checked in the vehicle's actual HVAC heater module for a ready-to-install "Drop-In Fit".
- Quality-built: engineered and manufactured under ISO TS16949 quality systems and 100% leak tested.
Signs the original core may need replacing include a sweet coolant smell inside the cabin, foggy or oily film on the glass, coolant on the passenger floor, or weak heat output. If a leaking or clogged heater core is the cause, this unit replaces it.
