How to access the water pump

Start by lifting the vehicle on the right side, removing the wheel and the inner fender mudguard. Visit our dedicated pages to see how to safely lift the vehicle and dismantle the mudguard.

How to remove the water pump from engine

Block the water pump pulley with a large screwdriver by inserting it in between the pulley and the water pump actuator.
Loosen all bolts holding the pulley to the water pump rotor.
Then simply take it out.
Release the water pump actuator by pulling out with your fingers the meant handle (left), unscrew its holding bolts (middle) and pull it to the top then let it rest somewhere nearby the engine support (right). No need to disconnect its electric cable.
The water pump is now clearly visible.
Its plastic body is held by the means of 5 bolts which are more or less easy to access except for the one on top as you need to loosed first the electric wire harness. See further below.
Insert your hand behind the engine support until you reach the cylinder head and you will immediately find the bolt that hods the wire harness leg which you need to unscrew (left) for loosening the harness and being able of moving it away from the pump's top bolt.

Remove all bolts and take out the pump.
You can now replace it with a new one if this was the purpose of your intervention.
If not, rotate the pump's impeller with your hand to make sure the bearing is still good. It should make almost no noise and stop fast due to the braking actin of its seal.

Replace the gasket if you are willing to reinstall the same pump or apply RTV gasket maker on top of it before refitting the pump.

Do not forget to bleed the coolant after refitting the pump and filling the coolant circuit.
