Gates Water Pump for Subaru Timing Belt Applications

The Gates 42030 engine water pump is built for Subaru timing belt-driven cooling systems that demand precise fit and dependable circulation. It uses a cast aluminum housing, stamped steel impeller, and reverse rotation design to match the specified application.

Compatible with 2008-2014 Subaru Impreza, 2012-2014 Subaru WRX, and 2008-2013 Subaru Forester, this Gates Water Pump (Standard) is a direct replacement for interference-engine vehicles that rely on accurate coolant flow and pulley alignment.

Key Features

  • Cast aluminum housing for strength and corrosion resistance
  • Stamped steel impeller with reverse rotation
  • Timing belt driven design with pulley included
  • Includes water pump and metal gasket
  • Two outlet configuration for the listed Subaru applications
  • Back housing, thermostat housing, and fan clutch not included

Product Details

Gates water pumps are manufactured with premium alloy materials and tested for seal and bearing function as well as leakage integrity. The 42030 is engineered for OE-quality fit in Subaru Impreza, WRX, and Forester models that use a timing belt-driven water pump. This part cross-references Beck/Arnley 131-2445 for the same application.

Common Cooling System Issues This Part Can Address

  • Coolant leakage from a worn pump housing or seal
  • Overheating caused by reduced coolant circulation
  • Noise from failing pump bearings
  • Timing belt service replacement on listed Subaru engines
  • Loss of pump efficiency from impeller wear

Installation Notes

Verify reverse rotation and timing belt drive before installation. Replace the pump during timing belt service on the listed Subaru applications, and confirm pulley alignment, gasket seating, and outlet routing during assembly. This part is listed for interference engine applications, so correct timing procedures are critical.

Quality Assurance

Gates tests each new water pump for seal and bearing function and performs leakage checks on both the casting and assembled unit. The brand positions this Water Pump (Standard) line as an OE-quality replacement solution for dependable operation.
