What does a water pump do?
Your car’s water pump is responsible for circulating the engine coolant around the cooling system. It is located in the engine bay and is usually powered from the engine drive belt.
How often should a water pump need replacing?
Due to the importance of their operation, water pumps are often replaced before they fail. It is recommended that a water pump be replaced between 60k and 90k miles of operation. It is also advisable that the timing belt, idler pulleys, and tensioner be replaced at the same time.
The law, vehicle regulations and your MOT
An obviously leaking water pump will fail an MOT. A very slight drip or suspected leak may cause an advisory measure, which given the impact a leaking water pump can have on the engine, it should be checked and replaced straight away.

What causes a water pump to stop working correctly?
