Gates Water Pumps are recognized in the industry for their durability and superior quality. Every Gates Water Pump is constructed with premium alloy materials and a 100% functional test of seals and bearings along with a 100% leakage test for both the casting and assembled water pump.

  • The shaft and hub are precisely ground to exactly fit original equipment fan clutches
  • The unitized seal protects the bearings and provides leak-free, long-life performance
  • The one-piece bearing assembly has factory-sealed bearings that are computer matched for low friction
  • The quality-forged housing is specially formed to ensure maximum coolant flow
  • The precision balanced impeller increases water flow, and extends seal and bearing life
  • The no-sealant-required gasket allows for fast, easy installation.
Every belt driven water pump has a weep hole that might leak a little in the beginning. Some seepage from the weep hole is normal during the break-in period (about 10 minutes), and does not indicate a defect.
Cooling System Maintenance | Tips & Tools

Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:

  • Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
  • Consider replacing the Radiator Hoses (and Hose Clamps), Thermostat and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
  • Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
