The Water Pump in GMC Jimmy cars is a critical component that transfers water and anti-freeze solution from the radiator to the engine where it gets hot as a result of combustion. Again, nearly all Jimmy models include a belt-driven water pump as a standard component; however, upgraded ice vehicles may have electric ones. Such pumps can equipped with the aluminum castings with a rotating shaft, which is based on the pulley with the impeller formed to move the coolant. The symptoms that are likely to indicate that the car's water pump is failing are leaks, noise coming from the bearings and cases where the engine overheats. For high-revving engines and race prepared engines there are high performance water pumps, these have better coolant flow than standard designs and less amperage draw. As we have already discussed electric pumps can also be used to get rid of parasitic power loss and for better control of circulation of coolant.
