Originally posted by LO3BIRD Yes my tiny serp belt is temp so my tire smokin ride is battery powered at the moment. I'll order the Stage 1 CCW tomorrow from Stewart. I'd get the aluminum Stage 2 if I thought it was worth $160 to me, but really I've never paid more than $20 for any water pump even with hopped up V8's and been doing fine (till now).
When it arrives, I'll remove the backplate and visual the impeller. If it's right, I'll probably faint from what I've been through.
FlowKooler's 1774 CCW was also $75, but had wrong impeller. It was just a ASC 715HD with 4 rivots attaching a disc to the back of impeller.
As far as the auto stores in my area, myself and others and truely mystified. Been racing Camaros for 15 years, never saw any trouble like this. Plus this CCW pump is used on many GM cars/trucks after 87. When my wife's LO3 pump finally dies, I guess I could drive to Michigan to get a $15 pump or order a Stewart for $75 (IF they hook me up right). Crazy....
I bet half the people on this forum (with cooling trouble) may have wrong impellers and don't realize it. A quick Google search reveals this is a common problem for Jeep, Ford, Audi, etc with serp systems & rebuilt units from auto stores. Even when the part # is right, the part is wrong in the box. But those non-Chevy's have no backplate, real easy to see impeller in the store...
OK so now you've got me thinking, I replaced my WP about 6 months ago and just assumed that the parts store guy sold mme the right one. So how do I tell the difference? Do you have any pics?

The pics I put up were pumps that didn't work out for me on my V8. Isn't an '89 V6 a 60degree motor (2.8, 3.1, etc)? Uses different pumps than (4.3, 5.0, 5.7).
If you got the 60degree motor I wouldn't worry too much, the front cover on the motor actually has a lot to do with proper water flow.
You could always get good gloves (be careful) and undo the top radiator hose (engine off but hot). Start it, should empty the hot radiator coolant from that hose pretty quick.
