Coolant pressure cap
 

Anyone know the GM part number for this? The one listed on the KWR site and parts CD is wrong. #10239665 is the overflow tank cap, I know because one is sitting in my lap after I bought what I thought was the pressure cap from GMPartsDirect... Thanks!

Hi Bob,

I know this is not the info you asked for but over at P&G Chevy the listing is for all 90 corvette rad. caps, no distinction L98 vs. LT5. It's a 16 lb cap according to AutoZone.com and their P/N's are the same for a L98 and LT5.

:cheers:

I have the same parts CD you do, I think, so I didn't bother using that P/N at P&G's site.
