Installation Notes and Tips

Verify connector style, voltage, and mounting location before installation. Because the pump is supplied without a gasket or seal, mounting hardware, bolts, or bracket, transfer or source the required service parts separately as needed. Inspect coolant hoses, electrical terminals, and surrounding components for leaks, corrosion, or heat damage during replacement.
