Dayco DP931 Engine Water Pump for Toyota Pickup and 4Runner

The Dayco DP931 engine water pump is a direct-fit cooling system replacement for select manual-transmission Toyota trucks and SUVs with timing belt-driven applications. It is listed for 1988-1991 Toyota Pickup and 1988 Toyota 4Runner, with fitment notes calling for timing belt service at the same time.

  • Fits 1988-1991 Toyota Pickup, N/A, 1/2 Ton; Manual; Timing Belt Driven, Replace Timing Belt w/Pump; To 02/90

Detailed Description

Use the Dayco DP931 when replacing a worn or leaking water pump on compatible Toyota Pickup and Toyota 4Runner models. This engine water pump is specified for 1/2 ton, manual, timing belt driven applications through 02/90, making it a focused fitment for owners servicing the cooling system on these vehicles. The DP931 part number is also useful when cross-checking catalog listings for the correct Toyota Pickup or Toyota 4Runner water pump.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Coolant leakage from a worn pump seal or housing
  • Overheating caused by reduced coolant circulation
  • Noise from a failing pump bearing
  • Cooling system service during timing belt replacement
  • Fitment errors when sourcing a Toyota Pickup or Toyota 4Runner water pump

Installation Notes and Tips

Confirm engine and production date before ordering, since this listing applies to vehicles built to 02/90. Because the notes specify timing belt driven service, replace the timing belt with the pump during the same repair. Verify gasket surfaces, coolant condition, and belt alignment before returning the vehicle to service.

Quality Assurance

Dayco is a recognized aftermarket brand for engine drive and cooling system components. The DP931 is cataloged as an engine water pump for the listed Toyota applications, supporting accurate replacement selection for maintenance and repair.
