Installation Notes and Tips

Verify the vehicle’s HVAC layout and match the heater core dimensions before installation. Confirm hose routing and connection points, since pipes are not included with this heater core. For best results, inspect the cooling system for contamination or debris before installing the new core, and flush the system if needed to reduce the chance of repeat restriction.
