|E38 750iL Water Pump|
Q. I have a 1996 750iL, and the water pump is dripping away. I don’t use the car much but I don’t fancy the letting the pump go. I don’t fancy paying the £650 I’ve been quoted to replace it either. Is this a massive job?

A. Well, they certainly aren’t easy! At least on the E38 the bonnet opens from the front which makes working on the front of the engine somewhat easier. I would take the radiator out first of all because space is at a premium with these. The viscous fan also comes off with a 32mm spanner (a proper one, not one of those pressed steel viscous spanners) and it’s a reverse thread, so clout the spanner clockwise with a steel hammer.
Having the rad out is a good opportunity to give it a good clean up, and reverse flush it. Check the bottom for bowing outwards as well – it’s scrap if it’s not completely straight.
