What Are The Signs Of Water Pump Failure?

The engine water pump is an important part of mechanical equipment and is responsible for circulating and transporting coolant. However, as time passes and the frequency of use increases, the water pump begins to malfunction, affecting the operation of the mechanical equipment. In this article, MyMROmarts will discuss the water pump failure signs and help you find and solve the problem in time to keep your machinery and equipment running smoothly.

 

What Are Signs Of Water Pump Failure?

The Water Pump Makes Abnormal Noises

When your water pump starts making unusual noises, such as squeaking, grinding, or high-frequency vibrations. This is often a telltale water pump failure sign. The cause of water pump failure may be bearing wear, impeller imbalance, loose bolts or pump body wear. When you hear abnormal noises from your engine's water pump, the best thing to do is to stop using the mechanical equipment immediately and have the water pump inspected and repaired. If this abnormal sound is ignored, it will cause more serious damage and further affect the engine and other diesel engine parts.

 

The Water Pump Is Showing Signs Of Leaking

If you notice water leaking from the bottom of your water pump or elsewhere, this is likely a sign of a damaged water pump seal. Damage to the water pump seal may cause the coolant in the pump body to flow out. In severe cases, it may leak into the engine, causing greater failure problems. Therefore, when you find that the water pump starts to leak, it is recommended that you replace the seal in time.

 

The Cooling Effect Of The Water Pump Decreases

The main responsibility of the engine water pump is to maintain the temperature of the engine. If you find that the temperature of the engine rises abnormally or the cooling effect begins to decrease. This is also a symptom of engine water pump failure, which is mainly caused by impeller wear, pump body clogging, pump shaft bending, or insufficient coolant pumping. It is recommended that you check the water pump in time and take necessary maintenance measures.

 

The Engine Water Pump Vibrates Obviously

When your water pump is operating with significant vibration, there probably is an internal issue with the water pump. The specific cause might be the water pump's loose pump body, damaged water pump bearings, or slack connection bolts. The high vibration of the water pump might harm other engine parts as well. Therefore, it is advised that you examine and fix the water pump as soon as you notice that it is vibrating excessively.

 

The Water Pump Flow Decreases

When the water pump starts to experience a reduction in coolant flow, it means the impeller is broken or there is a clog inside the water pump body. This symptom may be brought on by a buildup of suspended particles in the coolant, water pump body corrosion, or damage from foreign objects to the impeller. This situation will cause the flow rate of the water pump to decrease or the pressure of the water pump to decrease, thereby affecting the ability of the starter motor to start the engine and the normal cooling of the engine by the water pump when the engine is running. Therefore, it is recommended that you regularly check the flow of your water pump and remove any material that may cause blockage.

 

In conclusion, being vigilant for the signs water pump failing is crucial for maintaining the health of your mechanical equipment. These signs include abnormal noises, leaking, reduced cooling effectiveness, noticeable vibrations, and decreased coolant flow. When you detect any of these symptoms, it is essential to address the issue promptly to prevent further damage to your engine and its components. Regular inspections and maintenance can go a long way in ensuring the longevity and reliable operation of your water pump, ultimately keeping your heavy equipment running smoothly.
