Common Problems This Part Can Address

• Fogging or film on the windshield caused by coolant seepage
• Reduced heater performance from internal blockage or corrosion
• Coolant loss traced to the HVAC heater core

Installation Notes and Tips

Verify that the vehicle is equipped with air conditioning before ordering, since fitment is limited to A/C applications. Confirm the year, make, and model against the vehicle’s HVAC configuration and compare the original core before installation. Flush the cooling system and inspect hoses, seals, and related HVAC components so the replacement heater core is not exposed to contamination or debris.
