Gates marks its heavy-duty water pumps with an HD suffix on the part number, and every new pump is manufactured to ISO/TS 16949 standards. This Gates pump pairs a cast aluminum housing with a cast iron impeller, and Gates backs it with a guaranteed OE-quality fit.

• 100 percent tested: the unitized bearings and seals are 100 percent functionally tested, and both the casting and the assembled pump undergo a 100 percent leakage test.
• Precision machining: computerized machined surfaces for proper fit and sealing.
• Drive and rotation: accessory-belt driven, not timing-belt driven, with a reverse-rotation impeller.
• In the box: water pump and gasket. The pulley, fan clutch, back housing, and thermostat and housing are not included.

Signs a water pump may need replacing include coolant seeping from the pump, a growling bearing noise, a loose pump shaft, or an engine running hot. Diagnose the cause before replacing, since other cooling-system faults can cause similar symptoms. The listed applications use one pump. Gates covers it for 18 months or 150,000 miles/5,400 hours, whichever comes first. Country of origin: China.
