Why Does A Water Pump Go Bad?

The engine water pump is responsible for circulating coolant into the engine to maintain engine temperature. However, from time to time, we may encounter problems with the water pump, such as damage and noise. In this article, MyMROmarts will look at why engine water pumps go bad and why water pumps make noise.

How Does A Water Pump Go Bad?

Wear And Aging

Like other diesel engine parts, the engine water pump wears and ages over time. Long-term operation of mechanical equipment and high-temperature environments may cause wear of bearings and seals, causing the water pump to deteriorate.

Corrosion And Corrosion

Since water pumps are constantly handling coolant, water pump corrosion is also a common problem. Coolant will gradually corrode the metal parts of the water pump, destroying seals and blades over time. These problems can cause the water pump to deteriorate.

Engine Overheating

If the engine overheats, the engine water pump will be subject to additional pressure and thermal stress, which may cause the blades to bend or crack, or even distort the water pump casing in severe cases.

Impurities And Dirt In Coolant

Impurities and dirt in the coolant will accumulate at the bottom of the water pump, and long-term accumulation will hinder the normal operation of the water pump.

Why Water Pumps Make Noise?

Now, let’s explore why water pumps make noise. Water pump noise can be an unsettling problem that not only disturbs the operator but may also affect the water pump's cooling effect on the engine after the starter motor starts the engine.

Water Pump Bearing Problems

Water pumps usually have bearings to support the rotation of the shaft. If your water pump's bearings are damaged or worn, they can make noise. This noise is usually a low rumbling sound, similar to a grinding sound.

Water Pump Blade Problem

The blades of the water pump are responsible for pumping coolant from one place to another. If the blades are damaged or bent, they can produce a scraping or banging sound as they operate.

There Are Air Bubbles In The Water Pump

If there are air bubbles in the pump, they will move inside the pump and mix with the liquid, causing noise.

Understanding why water pumps break down and why water pumps make noise can help us take appropriate measures to prevent and maintain water pumps. Through regular inspections and careful attention to the health of your water pump, we can extend the life of your water pump and reduce the risk of mechanical equipment failure.
