Default Water Pump pully Walking Off

Hey lads

through a belt the other day due to my factory water pump pulley staring to walk off the post. Its about a 1/4 inch off !

Anyone else have this issue before? I spoke with Brett this morning and I think I may go the electric pump route. Any other options that anyone can think of?

let me know

I replaced my stock water pump as a maintenance item when I replaced the engine @ 30K mi. I put on a Bosch water pump, the front bell walked off on the 2nd dyno run. I replaced it with the one had taken off, it is still operating fine.

I tig weld the end where the hub and pulley meet, other than that I use the Edelbrock or the Evans water pumps with the bolt on pulleys.

Arun....is there any modification needed to the
"
1997-07 Corvette Water Pump, High Performance Victor Series by Edelbrock"
to make it fit ? Can we use the same thermostat housing?

Also...is the Edlbrock pulley the same diameter as stock?

"Corvette Water Pump Pulley, Billet for Edelbrock Victor Series Water Pump 627-350"


thanks bud!

Hey bud

If something can happen ...it will to me. I just ordered a new high flow edelbrock pump with a bolt on pulley.

I am worried about running an electric unit on the street.

You will be fine now. I welded my pump that walked on me to see if i could knock the pulley off and there is no way that's coming off now. I beat the sh@t out of it to try and get it off with no luck so the new one i have on there now i welded much better.:fla g:
