Installation Notes and Tips

Verify engine configuration and OE part number before installation, since fitment is limited to the listed GM vehicles and model years. Inspect the belt drive, hoses, and cooling passages during service, and replace coolant according to the vehicle manufacturer’s procedure. Confirm all sealing surfaces are clean before installing the included gaskets and housing assembly.
