A vehicle’s engine generates so much heat it can damage itself if it is not cooled down. The water pump, a container made of aluminum or iron, is part of the cooling system. It contains an impeller (looks like a fan) that circulates water and coolant throughout the cooling system, keeping the engine from overheating. It is located in the engine compartment. For the water pump to work, it needs to turn. This is accomplished either by the drive belt or timing belt/chain. If the water pump is not working, the coolant will not circulate through the cooling system causing the engine to overheat and get severe damages.
Common symptoms leading to water pump replacement:
- Coolant (green, red or yellow fluid) is leaking. It often pools under vehicle.
- Vehicle is overheating
- Vehicle will not start
Other notes to consider:
- When the water pump is replaced, the drive belts and timing belt/chain may need to be replaced as well.
- The entire cooling system should be inspected when the water pump is replaced.
- Replacing the thermostat at the same time as the water pump can help prevent future problems.
- If you see coolant (green, red, or yellow fluid) underneath your car, have the cooling system inspected for leaks.
- Always keep up with the service intervals as specified by the manufacturer and get the coolant replaced. It is a good practice to get the coolant replaced every 50,000 miles. This will help ensure a long life for the water pump and the entire cooling system.
