How do you change water pump on 1997 olds achieva 2.4?

On the quad 4 engine the water pump is on the back of the engine. For your application the consensous is that you must pull the timing cover off and insure that the twin cams remain in the same position. Then you remove the exhaust manifold in order to remove the water pump. I got an estimate and the mechanic said he wouldn't touch it for less than $600.

Another site you could log onto is www.Quad4forum.com. These people are quad 4 enthusiates. I hope I have been of service.
