I have a 1993 Pontiac Sunbird with a failing water pump, I have some friends that seem to believe that I will need to take the timing belt off the car to replace the water pump. Do I need to take of the timing belt to replace the water pump?
Also, is there anything like engine mounts or any other major task that has to be done before removing the water pump?
I have never done a water pump on a Sunbird but I did a few on Neon's and Intrepids are they similar to replace as a Sunbird?

Isn't that a 3.1 in the picture Ras? He has a 2.0 belt driven pump. There are 3 duplicates of this question.
