Gates Engine Auxiliary Water Pump,Engine Water Pump P/N:43327BH
Gates 43274BH water pump for the 2011-2016 Chevrolet Express 2500 V8 6.6L and other vehicles circulates coolant through the engine. This engine water pump runs off the accessory belt.
Coolant seeping at the pump, a grinding or whining noise from the bearing area, or an engine running hotter than normal can mean the pump is wearing out. A leaking hose, a stuck thermostat or a slipping accessory belt can be behind overheating too, so track down the actual cause before you buy.
It fits and performs exactly to OE specifications and requirements, and it is listed for a wide range of Chevrolet and GMC models, including the 2011-2016 Chevrolet Express 3500 V8 6.6L and the 2011-2016 Chevrolet Express 4500 V8 6.6L. If your vehicle isn't named here, look up its year and engine in the "Vehicles it fits" section.
