Water Pump Bearings

Water pump bearings generally refer to the bearing of the car water pump shaft. The automobile water pump shaft bearing is a type of bearing. The cage material is usually reinforced nylon 66, and the sealing ring material is generally nitrile rubber. When the requirements are higher, a fluorine rubber sealing ring can also be used.

Symptoms of a failing water pump bearings

Noise – Open the cover and start the engine. If you hear a low frictional noise, the bearing of the water pump may be broken. If it is broken, the sound is obvious.

Unsteady idling– The failure of the water pump can cause the rotation resistance of the water pump to increase. Since the water pump is connected to the timing belt, the increase in the rotation resistance of the water pump can directly affect the rotation of the engine. When idling, it is manifested as a jump of the speed after starting, which is more obvious in winter and can even cause flameout.
