Installation Notes and Tips

Verify pulley style, drive type, and mounting layout before installation. This pump uses a bolted attachment method and does not include mounting hardware, so reuse or replacement of related service parts should be planned separately. Confirm the gasketed sealing surfaces are clean and inspect the cooling system for contamination before installing the new pump. Part number MWP-538 should be matched to the vehicle application and engine configuration before service.
