Overheating from reduced coolant flow
Leaks at the water pump housing or seals
Noisy operation from a failing pump bearing
Timing belt service intervals that call for pump replacement

Installation Notes

Verify engine code, hose routing, and timing belt drive configuration before installation. On timing belt driven Subaru applications, replace the timing belt with the pump during the same service to reduce repeat labor. Confirm the three hose connection layout matches the original part before assembly. Dayco DP418 should be matched to the vehicle by year, make, model, and cooling system configuration.

Quality Assurance

Dayco DP418 is cataloged as an engine water pump for specific Subaru and Saab applications. Part number DP418 should be verified against the vehicle’s original cooling system layout and service requirements before installation.
