I need the rundown on how to remove the water pump on a 1988 nissan maxima. Can you provide me with a procedure and diagram of the removal if possible? It is a 3.0L V6 automatic 4dr. Sedan.

Go get a Haynes manual and save yourself a lot of headaches. You can also check You Tube. Crowded space and not an easy job.
