Why Does My Water Pump Keep Failing

The engine water pump is in charge of keeping the engine cooling system running normally. Although the operation of the water pump appears simple, it is critical to the engine. However, many people have encountered the problem of water pump failure. In this article, MyMROmarts will work with you to understand the working principle of the engine water pump as well as common failure causes and troubleshooting methods.

 

How Does Engine Water Pump Work

The engine water pump is a centrifugal pump that usually consists of a metal casing, impeller, and bearings. Its working principle is based on the principles of centrifugal force and suction. The engine water pump draws the coolant out of the engine, then dissipates the heat through the radiator, and finally returns it to the engine. The temperature of the engine is always kept within a controllable range, ensuring the normal operation of the engine and other diesel engine parts.

 

Stage of suction

The impeller begins rotating rapidly as the water pump begins to operate. The coolant is drawn into the water pump's input by the action of centrifugal force.

 

Stress Level

When the coolant is drawn in, the impeller's movement swiftly pushes it toward the water pump's exit. Pressure is produced as a result of the coolant's speed increasing due to the impeller's spin. Coolant is forced into the cooling system by this pressure.

 

Cooling System

The engine's temperature is lowered as a result of the coolant passing through the radiator and cooling lines after being pushed into the system by the engine water pump. The suction and pressure steps are repeated once the coolant has finished cooling the engine and has been returned to the engine water pump. This procedure is regularly done to ensure that the engine is always kept within a safe temperature range.

 

Why Does My Water Pump Keep Failing

Over time, the engine water pump in mechanical equipment will begin to slowly deteriorate due to continued use and gradual wear. Before your engine water pump begins to fail, it is necessary to understand the causes of common water pump failures so that early detection and maintenance can be carried out. This will ensure that your mechanical equipment can resume normal operation as soon as possible after your starter motor starts the engine.

 

Water Pump Impeller Wear

The water pump's impeller will wear down over time, reducing its efficiency. This will also impair water pump performance, resulting in inadequate cooling capacity for the engine.

 

Water Pump Bearing Failure

The water pump's bearings help the impeller's spinning. The water pump won't operate smoothly if the bearings are worn or broken. The typical remedy is to replace the broken impeller or bearing with fresh components. This is the quickest approach to get the engine water pump back to working normally.

 

Water Pump Seal Leaking

The seal of the engine water pump is key to preventing coolant leakage. If the seal is damaged or aged, coolant leakage problems will occur. If your water pump's seal is leaking, you can try repairing or replacing the seal.

 

Water Pump Corrosion And Blockage

The water pump may get clogged or corroded as a result of impurities and corrosive chemicals that might build up from the coolant, which will lower its performance. By frequently cleaning and flushing it, you may help your water pump last longer.

 

Water Pump Drive Belt Problem

A transmission belt drives the water pump. The water pump will not function correctly if the transmission belt is worn or loose. It is advised that if there is a problem with the drive belt, you examine and fix it as soon as possible.
