I have a 1993 ford taurus 3.8L V6 automatic GL. I need to replace my water pump. I removed the drive belt and took off the four water pump pulley bolts. I am having trouble removing the "bottom" water pump-to-engine retaining bolts. I can't see the "bottom" bolts and can't get any type of wrench to come close to the bolts. I am looking down on the engine. Any solutions?

Put the car on jack stands. Work from the bottom. You will probably be needing 10mm combination wrenches.
