Why does my water pump make a noise?
A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. Worn belts, or worn belt tensioners can cause a belt to be loose. This can result in the water pump not turning as fast as it should, and then the engine overheats.
What kind of noise does a water pump make?
Water pump noise is not common but does happen. Steady tone noise is more common such as groans or squeals. Rhythmic noise is less common.

What can I do about a noisy water pump in my car?
The only fix for a noisy water pump is to replace it. Because of its location (often under the timing belt cover and bolted to the engine block), an awful lot of parts have to be removed to get to it, so it can take several hundred dollars worth of labor to replace a $50 part.

How does a water pump work in a car?
The pump is operated by the engine’s drive belt – as the belt turns, the pump turns. Blades on the pump force coolant to flow through the engine and back to the radiator to be cooled by a forced air cooling fan. Although the water pumps in most modern cars, trucks, and SUVs will last a long time, they are by no means indestructible.
Why does a new water pump make noise?
The seal needs to slide smoothly, if there is extra friction a stick-then-slip rhythm can occur, resulting in noise. The spring in the seal can be the driver for the rhythmic nature of the noise. New seals need some run time to burnish and hone the surfaces. Before this they can be noisy and exhibit some seepage.
How does the water pump in a car work?
The water pump in your car’s engine is designed to circulate coolant through the cylinder heads and main block to keep the engine from overheating while in operation. This pump is driven by a main serpentine belt or timing belt which rotates an impeller that is submerged in coolant in the front part of the engine.
How to tell if your car’s water pump is going out?
If the water pump pulley is noticeably offset then you know the bearings are bad. Also grasp the pulley or use a large flat blade screw driver and to the move the pulley back and forth on its axis, it should have little to no play. Excessive play is an additional indication the bearings have failed. Got Questions?
