Water pump change

Place a recovery tray (5L) under the radiator on the left side

Disconnect the lower radiator hose, allow the fluid to drain into the tank

Reconnect the hose (This will prevent you from forgetting anything later...)

Before loosening the belts, unscrew the 3 screws of the water pump pulley (2-3 turns)

Remove completely by unscrewing the blue nut

Loosen the water pump belt by unscrewing the tensioner roller

It is not necessary to remove the alternator to loosen the belt, just release it.

To do this, completely unscrew the upper tension nut

Simply loosen the lower retaining nut a few turns.

Disconnect the radiator and heater core hoses

Remove the belts then finish removing the water pump pulley.

Unscrew the 6 screws holding the water pump

Remove the water pump (tap it lightly if it remains stuck)

Detach the gasket by sliding a cutter blade between the gasket and the cylinder head

Clean the gasket surface thoroughly (and possibly take the opportunity to clean the cylinder head/block)

Compare the 2 pumps (the new one has 3 locations for temperature probes)

Retrieve the alternator mounting bracket and mount it on the new pump (Do not tighten it completely)

Put the new seal in place

Place the new pump in place and gradually tighten the 6 screws.

Reconnect the radiator and heater core hoses

Replace the water pump pulley, and tighten it completely.

Replace the 2 belts

First engage the alternator belt (the smaller of the two) since it is behind... then the water pump belt (the larger of the two)

Reassemble the tensioner roller and tighten the belt (by tightening the orange screw) until you obtain a slight deflection when you press with your thumb.

Re-engage the alternator belt into the alternator pulley.

Stretch it by "spreading" the alternator and tighten the 2 fixing screws as well as that of the fixing bracket on the water pump

Check the tension (slight arrow when pressed with the thumb)
