Leaking Waterpump?

[TommyL]

I got my 90 out of storage yesterday and found a small pool of coolent under it. I filled it up (took maybe a liter) and drove around a little then home. It didn't over heat and worked very well. Today I see another small pool of coolent under the front cross member right about where the pump is, had a look with the flashlight and it has a drip every so often from the bottom of the waterpump.. looks like its leaking from the gasket?

My question's are: Where can I get a reasonably priced pump and gasket? How much work is it to change? Does anyone have detailed instruction on how to go about this?

Looks like it may take a little time to do this job and while I'm at it is there anything else I should look at?.

Thanks, Tom
