Product Details

Gates Water Pump (Standard) part number 42229 is engineered for OE-quality fit on HD truck cooling systems. Gates builds each new pump with premium alloy materials and performs functional testing of seals and bearings, plus leakage testing of the casting and assembled unit. This makes the Gates 42229 a direct replacement choice for Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD applications that use a reverse-rotation, accessory-belt-driven pump.

This part cross-references GMB 130-4030 for the same application.

What It Helps Address

  • Coolant leaks from a worn pump housing or seal
  • Overheating caused by reduced coolant circulation
  • Bearing noise from a failing water pump assembly
  • Impeller wear that can reduce coolant flow
  • Fitment issues when replacing the original HD truck pump

Installation Notes

Verify reverse rotation and accessory belt drive configuration before installation. Confirm pulley alignment, inspect the mating surfaces, and replace the included O-rings and metal gasket during service. Follow the vehicle service procedure for coolant refill and system bleeding after installation.

Quality Assurance

Gates tests seals, bearings, and leakage on each new water pump to support consistent operation and OE-quality fit. The 42229 is built for dependable service in compatible Chevrolet Silverado HD and GMC Sierra HD cooling systems.
