Installation Notes and Tips

Verify the core dimensions and hose connection layout before installation. Because pipes are not included, reuse or source the correct vehicle-specific connections as needed. Flush the cooling system and inspect related HVAC components, coolant hoses, and seals before installing the new heater core to reduce repeat service.
