Chevrolet S10 Water Pump

The Water Pump in Chevrolet S10 vehicles helps pump the coolant from the radiator to the engine so as to draw off and dissipate heat produced through combustion. In standard configuration, most S10 Water Pumps are of the auxiliary system which means they are powered by a belt from the crankshaft although new models come with electric pumps. These pumps normally come with aluminum castings with a running shaft, belt installed pulley and impeller to circulate the coolant in the system. The signs of the failing Water Pump are thus, coolant leaks, noises produced due to worn bearings and finally high engine temperature. High Performance Water Pump can offer numerous upgrades for high performing engines regarding to coolant flow and less power draw than standard pumps. Electric Water Pumps are also available that have advantages like flow of coolant independently of the engine, cooling after the shutdown of the engine and the possible remote mounting whilst occupying less space.

Each OEM Chevrolet S10 Water Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
