Not part of the timing belt,,
Its a bit of a job, you will need a tool to remove the gear that goes over the shaft of the water pump to do the job.
You need all the oil out of the engine, as the water pump when removed allows water to go into the sump..
The engine needs lowering to get access ..

 

Thank you very much for your very accurate reply.

Vehicle Build Code That tells us its A mark 4 Espace with a G9 engine fitted..


Yours runs off the cam belt and straight forward to do, its crank pulley off, Aux belt off, top cover. bottom cover that covers the cam belt..
Get your engine to Top Dead Centre, Take the belt off, replace new pump, New belt kit, New aux belt..

 

thanks.. it just clicked it was the type code after I posted.
