Understood. Pump wasn't running though as car was quietly idling away whilst I washed it ! Confident it's seized, and has now got so hot will only be salvagable by professional repair

I have located a secondhand one but has slightly different outer casing. I know there were variations over the years, and parts shared with Granada/Scorpio. Anyone know for sure if they are all interchangeable ?

I'll probably just buy it, and suck and see, as they are thin on the ground
