How do you change a water pump on a Renault kangoo express van?

To change the water pump on a Renault Kangoo Express van, first ensure the engine is cool and disconnect the battery. Remove any components obstructing access to the water pump, such as the timing belt or serpentine belt. Drain the coolant from the system, then unbolt and remove the old water pump.
