Installation Notes and Tips

Confirm pulley groove count and engine application before installation, especially on Mercedes-Benz Sprinter 2500 and Sprinter 3500 diesel models. Inspect the belt drive, mating surfaces, and coolant passages during replacement, and replace the gasket supplied with the pump during assembly. Verify proper coolant fill and bleed procedure after installation to restore normal system operation.
