How do you change a water pump on a Audi 80 1992 2 liter 4 cylinder?

remove/clean surfaces and install new one...don't overtighten bolts... also Everyone should have a manual for their vehicle, and the local library should have a professional shop manual available to make copies of for FREE...make the time to take time to read up on your vehicle, and work like the PRO'S! Good luck :) Dave
