Installation Notes

Verify the vehicle’s engine and accessory belt configuration before installation. This pump uses standard rotation and an accessory belt drive, so it should be matched to the original setup on the vehicle. Inspect the mounting surface, coolant passages, belt condition, and adjacent cooling components before reassembly. Use the included gasket and bolts during installation, and refill and bleed the cooling system according to the vehicle service procedure.
