I'm in the middle of replacing the water pump on a 1998, Lumina, 3.1,
sedan. I have a few dumb questions (the only kind I know how to ask).
1. Does the little raised triangular stud on the pump signify the top?
I didn't mark the old one when I took it off.
2. Should a gasket compound (like Permatex HI Temp RTV Silicone Gasket
Maker) be put on both sides of the gasket or is it just necessary to
put it on one side to keep it in place? Should it be put on light or
3. The Haynes manual says to clean the mounting screws but I can't
quite seem to be able to get all the crap out of the threads. How
clean do they have to be and what's the best way to do this?
4. Do the mounting screws have to be coated with the gasket maker too?
