Installation Notes

Verify engine application, model year, and position before installation. Inspect the mating surface, coolant passages, and hose connection for wear or contamination before assembly. Because bolts are not included, reuse or source the correct fasteners separately as needed. Follow the vehicle service procedure for coolant draining, bleeding, and refill to help prevent air pockets in the cooling system.
