What is the function of a BMW 5-Series water pump?

The water pump circulates the coolant through the engine and radiators. Together with the thermostat, it maintains the engine within its operating temperature range. Most engines have a mechanical water pump driven by the timing belt or an accessory belt.

When should you change the BMW 5-Series water pump?

If the water pump is driven by the timing belt, it is strongly recommended to replace it at the same time as the timing belt kit. Signs of failure include: coolant leak from the pump weep hole, grinding or whining noise, engine overheating.

Is it difficult to change the BMW 5-Series water pump?

Difficulty level 2/5: technically easy if replaced as part of a timing belt kit change. If replaced independently, the timing belt must be removed and refitted, requiring engine timing tools.
