How do you replace the water pump on a 1995 Buick Riviera? has free online manuals, i have gotten fuse box diagrams and component locations etc from them and they tell you step by step how to do it Bad answer! There is no manual available at Auto Zone. I have a '95 Buick Riviera and when my water pump went out I had to remove the belts, alternator, and most everything that was around it to replace it. Good luck!
