Dayco DP237 Engine Water Pump

The Dayco DP237 engine water pump is a direct-fit replacement for select Subaru timing-belt-driven applications. It is built for Subaru WRX, WRX STI, Forester, Impreza, and Legacy models that use a belt-driven cooling system and two hose connections.

Key Features

  • Engine water pump for Subaru cooling system service
  • Timing belt driven design for matched maintenance intervals
  • Two hose connections on applicable Subaru platforms
  • Direct replacement for select 1991-2016 Subaru applications
  • Dayco DP237 part number for accurate ordering and fitment lookup

Detailed Description

Dayco DP237 is an engine water pump for Subaru vehicles that require timing belt-driven cooling system service. It fits 2015-2016 Subaru WRX, 2009-2014 Subaru Impreza, 2013-2014 Subaru WRX, 2013-2014 Subaru WRX STI, 2009-2013 Subaru Forester, 1994 Subaru Legacy, and 1991-1993 Subaru Legacy. For these applications, the timing belt should be replaced with the water pump during service, and several listings note two hose connections. If you are searching for a Subaru WRX water pump, Subaru Forester water pump, or Subaru Legacy water pump, DP237 is the matching Dayco part number to verify.

What It Helps Address

  • Coolant circulation problems caused by a worn water pump
  • Overheating from reduced coolant flow
  • Leaks at the pump housing or hose connection points
  • Noisy operation from a failing timing-belt-driven pump
  • Timing belt service intervals that call for pump replacement at the same time

Installation Notes

Confirm engine configuration and hose connection count before installation. On the listed Subaru applications, replace the timing belt with the water pump during the same service interval. Verify gasket surfaces, coolant condition, and belt alignment during reassembly. This part cross-references no additional part numbers in the provided data.

Quality Assurance

Dayco is an established aftermarket brand for engine drive and cooling system components. DP237 is cataloged for the specific Subaru fitments listed above, including 2015-2016 Subaru WRX and 2009-2013 Subaru Forester applications.
