Water Pump Woes

Hi All
Been a while since my last post, what can I say, these E30's just keep on ticking, but now I desperatly need advice from those in the know.

Yesterday on the freeway, my water pump unceremoniously announced it's retirement from service in a shower of water and ball bearings, and I just did the cam belt 10 000Km ago.............I know, I know, I don't want to hear it
This morning I picked up a new one, jumped in to what I thought to be a quick one hour job.............yeah right, the problem is, I can't get the old one out.
Inserted two bolts into the lugs to push it out and the bolts broke off like butter, and yes all four bolts are out, I do not have access to a sliding hammer, or puller of any sort, this thing has to run or I ai'nt going to work tomorrow, any Ideas.........pleeeez?????
Problem is years of white corrosion I would imagine.
Oh, 318i M40 motor.

When in doubt, use full throttle,
it may not improve the situation, but it will end the suspence.

OK, sorted, I had an idea the pump was on dowels, turns out it is not, so a water pump pliers and some twisting did the job, took it for a ride and runs as cool as a cucumber, damn, I love my Beemer.
Another question, for a while now, the temp gauge is jumping around quite erraticaly no full scale deflection or any thing but jumping around about a quarter quage reading from where it sits, temp runs at between quarter and half.
Is this a sender unit on the way out, or the SI betteries? All the other gauges are rock steady and accurate, including the fuel consumption gauge.
This makes me suspect a sender, any idea which one it would be?

I believe there is a nut on the back of the guage that grounds the unit. This nut has been known to work loose. Make sure it's tight.

Thanks Pete, as always, you are a mine of information, will climb into it next weekend.

Does that cooling system need to be bled like the six cylinder? An air bubble could cause that.

Hi Al, yes it does need to be bled, and I have, it is up to spec, it has been doing it for some time, not just since the water pump replacement, I will give it another bleed to be sure, before I start pulling out gauge clusters.
