Here are the Characteristics and How to Resolve a Damaged Car Water Pump!

The water pump in a car is an important component in the engine cooling system. Its main job is to pump coolant, usually water mixed with coolant, through the engine to keep the engine temperature stable and prevent overheating. If the water pump is not functioning properly, the cooling circulation in the engine will be disrupted, causing the engine temperature to rise and potential engine damage. Therefore, the water pump is one of the important components to be considered in the care and maintenance of motorized vehicles. Check out the explanation of the functions, characteristics, and how to overcome car water pump damage from  TransTRACK!

Car Water Pump Function

The water pump in a car has several main functions:

Pumping Coolant

The main function of the water pump is to pump coolant (usually a mixture of water and coolant) through the engine to absorb the heat generated by combustion and other engine components. This helps to keep the engine temperature within a safe and optimal range.

Maintains a Stable Engine Temperature

By ensuring proper coolant circulation, the water pump helps prevent the engine from overheating. A stable engine temperature is important for good performance and engine longevity.

Optimizing Engine Performance

Excessively high engine temperatures can cause a variety of problems, including decreased engine efficiency, increased emissions, and the risk of engine component damage. A water pump helps keep the engine temperature at an optimal level for best performance.

Reduces Risk of Engine Damage

By preventing overheating, the water pump helps reduce the risk of serious engine damage, such as cylinder head leaks, bearing damage, or deformation of engine components due to overheating.

Increases the Life of the Cooling System

By ensuring proper circulation and keeping the engine temperature stable, the water pump contributes to the overall lifespan of the cooling system, which in turn helps to extend the overall lifespan of the engine.

Thus, the water pump is an important component in the car cooling system that has a significant impact on engine performance and reliability.

Characteristics of a Damaged Car Water Pump

The characteristics of a damaged car water pump can be seen based on the following criteria:

Car Engine Sounds

If the water pump is damaged, you may hear strange noises coming from the front area of the engine. This could be rattling, rustling, or other unusual sounds. This happens because the internal components of the water pump may be worn or damaged.

Radiator Fan Doesn’t Stop Rotating

The water pump is a part of the engine cooling system that also affects the operation of the radiator fan. If the water pump is damaged, the radiator fan may not stop spinning even when the engine is off. This is due to the lack of coolant circulation which is usually regulated by the water pump.

Radiator Fan Cannot Turn

Conversely, if the water pump is completely broken or malfunctioning, the radiator fan may not turn at all when the engine is hot. This can lead to engine overheating due to lack of cooling.

Water Leaks on the Front or Side of the Engine

A faulty water pump can cause water or coolant leaks around the water pump area. You may see signs of moisture, wet spots, or even coolant spillage on the front or side of the engine.

Damaged Water Pump Vane

The water pump impeller is the part that pumps coolant through the engine. If these vanes are damaged or chipped, coolant circulation will be disrupted, which can lead to engine overheating.

Radiator Water Does Not Circulate

A damaged water pump can inhibit the circulation of coolant, resulting in radiator water not circulating properly. This can be seen from the rising temperature indicator or other signs of overheating.

If you experience one or more of the above characteristics, it is highly recommended to immediately have your vehicle checked by a repair shop for further diagnosis and repair. Water pump damage left unaddressed can cause serious engine problems.

How to Overcome a Damaged Car Water Pump

Here’s how to overcome a damaged car water pump, see the explanation:

Empty the Water in the Radiator

Before performing repairs on the water pump, it is important to empty the water or coolant from the cooling system. This is done to prevent spillage and facilitate access to the water pump. Make sure the engine is cool before opening the radiator to avoid the risk of burns.

Replacing a Damaged Water Pump Drive Belt

The water pump drive belt is an important part that connects the water pump to the engine crankshaft. If this belt is damaged or worn, the water pump will not function properly. Replacing the damaged drive belt with a new one will ensure the water pump can operate optimally.

Replacing a New Water Pump

If the water pump has suffered severe damage or is beyond repair, it is best to replace it with a new one. The water pump replacement process involves disassembling several parts of the engine, including coolant removal, drive belt removal, and disassembling the old water pump. Afterward, the new water pump can be carefully installed and reattached to the engine. Make sure to use a water pump that is compatible with your car and follow the proper installation instructions.

In addition to these steps, it is also important to check other components in the cooling system such as the thermostat, coolant hoses, and radiator to ensure there are no additional issues that could affect the overall performance of the cooling system.

If you do not have enough experience or knowledge, it is advisable to entrust the water pump repair to a skilled and experienced mechanic to ensure the job is done correctly and safely.
