God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Damn water pump

So today i started on replacing my water pump. Drained the cooling system and took the drive belt off and that with no worries but the pump is jammed in there good. the jack bolts aren't doing it either. Im hoping its just the o-ring making things difficult and not any corrosion. gonna try and do some serious prying and yanking tomorrow without damaging the timing case. If anyone's got any ideas on how to loosen things up that would be great. Its on an M42 btw.

Thanks guys,

Bret

A vote for partblaster, kroil, or something similar for loosening up the pump.

Best thing I've seen so far:

Another guide

http://www.esatclear.ie/~bpurcell/31...html#waterpump

The pump is held in by four bolts. The sneaky bolt in the DIY above is the hex/allen bolt (shown removed, it's the left most red circle in the second photo). Expect some coolant to spill out once you get the pump removed.

I'm grateful to have had a salvage yard M42 to practice on, as it will come in handy when I have to do it to my own M42.

Adios for now,

RM

woooo! 7:20pm and i finally got the f***er out, through a black out and all. turns out it was just in there real good. had to make a brace almost an inch thick and jack bolt the thing out, seeing as the original jack bolts just broke away the frame... will clean everything and put the new one in tomorrow. Thanks for all your support.

Congratulations -- well done on getting through this phase of the repair.

If you made some pictures along the way of your brace setup, please post them.

Adios for now,

RM

ok so heres some pics of the bracket me and my old man put together. drilled a hole in the middle to go over thread for the fan, two threaded holes to bolt on to the pulley mount on the pump and two threaded holes on the outer to jack on to spacers placed over the bolts on the timing cover so as not to damage it. sorry the pics arent very good quality, just taken on my mobile. If u have any questions, just ask.
