  • Supports proper defrost and cabin comfort in rear HVAC-equipped vehicles

Installation Notes and Tips

Verify core dimensions, tube size, and rear HVAC routing before installation. Flush the cooling system and inspect hoses, seals, and clamps for contamination or wear before fitting the new core. Because heater core replacement often requires access through the HVAC case, confirm vehicle-specific service procedures for the Chevrolet Traverse, GMC Acadia, or Buick Enclave before beginning the repair.
