To remove the water pump, start by draining the cooling system and raising the front of the car. Remove the driver's-side engine lower cover and loosen the water pump pulley bolts. Remove the auxiliary drivebelt and then the water pump pulley. Unscrew the bolts and nuts to withdraw the water pump, being prepared for water spillage. Inspect the pump for coolant leakage and listen for any noisy bearings. When refitting, clean the mating faces of the water pump and cylinder block and use a new gasket. Tighten all fixings to the specified torque and refill the cooling system.

A failure in the water pump can lead to engine damage due to overheating.

To remove the water pump on 2009 and earlier models, you should disconnect the cable from the negative terminal of the auxiliary 12-volt battery, drain the cooling system, and remove the engine drive belt.
