Installation Notes

Install as a direct replacement in the listed front HVAC applications. Verify the vehicle’s AC configuration and notes before ordering, since some fitments are listed with w/o AC and one application is marked N/A for position. Use the supplied foam and accessories as provided, and confirm the heater core matches the original layout before reassembly.

Each heater core is individually pressure tested. OSC states that these premium new heater cores are made to OE form and function and use aluminum construction with plated tubes to help improve service life.
