Do you have the bigger heavy duty water pump? If you do those are serviceable, I have a GMC Manual that mentions this. I'll look it up to see what the procedures are or you can find a local rebuilder. The smaller pumps are the same as mid 50's and early 60's Pontiac V8's good chance those are still be produced.
