It is a common scenario especially on long trips to pass by vehicles parked at one side of the road with an open hood to let the smoke evaporate on air. Have you been into that scene, too? Not with your GMC vehicle. But sooner or later expect that even with a GMC vehicle you are not spared from having engine overheating. The engine overheating is usually caused by a bad water pump.
The GMC water pump is a device that lets the liquid circulate through the cooling system by pumping it from the engine water jackets to the radiator. The GMC water pump is usually mounted at the front of the engine driven by a belt from a pulley on the front end of the crankshaft. The GMC water pump circulates the liquid whenever the engine is running. In order to make the fluid move the water pump uses centrifugal force. The fluid or the coolant that was sent by the water pump through the water jackets into the radiator helps remove the excessive heat from the engine.
The outer side of the water pump has a pulley mounted on the shaft which is rotating on the bearing pressed inside. The inner part of the water pump has a seal to keep the coolant from leaking. The water pump is usually driven by the so-called serpentine belt or V-belt but some water pumps are driven by timing belt. If the GMC is not functioning properly, the engine coolant will not be delivered to the radiator to compensate the heat. If there is no cooling from the radiator it means that overheating is not far away to happen.
Always make sure that your GMC water pump is properly functioning otherwise, it may cause serious engine damage. It is also better to be aware of the signs of a bad water pump. Some of these signs include coolant leaks, noisy or defective bearing and damaged or corroded impeller. It is also recommended that periodic check to determine water pump leakage be done. Preventive maintenance is the best way to make your GMC water pump function beyond its lifespan.
If water pump failures continue to persist then replace it with a brand new GMC water pump from Parts Train. Parts Train is the place where you can purchase well-engineered GMC water pump that will keep your engine cool as well as your head from being spared of spending much in replacing GMC water pump.
