Water Pump Help!
I "Think" I need to replace my water pump. Currently the car has GM # 9975928. Hopefully I got right number off the pump and got it right lol.
Anyway... what is on there currently and can anyone point me in the direction of getting a replacment?

This is the number I got off the pump...9975928. I dont get any results.

Note that there are 2 types of short pumps. The Vette pump is specific to the Vette and has a larger center shaft. I believe it's 3/4ths of an inch in diameter for the small block.
I don't know about the Big Blocks. I looked on Jegs for you and I don't see a Corvette specific pump there for a Big Block. Someone else will have to chime in on big blocks.
If you're concerned about numbers matching and want to keep the original I believe they can be rebuilt.
Good luck.

Couldl be leaking at the gasktes that mate the water pump to the block...you said that you tighten one it may have made the problem worse...pressure test & check again.

I have a 427/390 engine and I replaced the water pump this past summer. I installed a Stage 2 pump from Stewart. The new pump works great. No problems.

I recommend the one from G.M. it's only a few more $$ than an after market one.
