Why Do Water Pumps Burn Out

The engine water pump is an integral part of the mechanical equipment and is responsible for delivering coolant from the radiator to the engine. However, water pumps in mechanical equipment sometimes have some problems. In this article, MyMROmarts will discuss why water pumps burn out, and explain why water pumps have drainage holes and their importance.

Why Do Water Pumps Burn Out

High Temperature And High-Pressure Environment

Mechanical equipment often works in high-temperature and high-pressure environments, which puts a lot of pressure on water pumps. On the other hand, prolonged high temperature and pressure may cause the water pump seals to harden and age, causing the water pump to leak or rupture.

Wear Water Pump Blades

There is a rotating blade inside the engine water pump that drives the flow of coolant. Over time, these blades can become dull due to wear, causing the pump's performance to decrease, or even causing the pump to fail completely in severe cases.

Coolant Corrosion

Coolant contaminants and chemicals have the potential to corrode the water pump over time. The metal components inside the water pump will be harmed by corrosion, which will reduce the water pump's ability to function effectively.

Excessive Use Of Water Pumps

If the mechanical equipment is often overused or often works in a harsh environment, the water pump may wear out and be damaged prematurely, affecting the normal operation of the engine and other diesel engine parts.

Why Do Water Pumps Have A Weep Hole

Now let’s discuss the drain holes on your water pump and their importance. Since gas and air bubbles form inside the water pump, they will seriously affect the normal operation of the water pump. The water pump is usually designed with one or more drainage holes, whose main function is to remove gas and air bubbles from the coolant.

In order for gas and air bubbles to leave the water pump and enter other components of the cooling system, a drain hole must be made. In this approach, the starter motor will start the engine to guarantee that the water pump can function smoothly and the water pump will always be filled with coolant. In the absence of a drain hole, gas and air bubbles can block the water pump, resulting in poor coolant circulation and eventually overheating of the engine.

Drain holes also aid in clearing the cooling system of debris and pollutants. If not quickly removed, these pollutants may harm the water pump and other cooling system parts. These contaminants may infiltrate the cooling system.
