Diverter Valve.....Unknown Part Number

[Richard K.]

Many years ago, before I knew much about diverter valves, my local Corvette repair shop ordered a new diverter valve for my '69 350/350. On this diverter there are some identification numbers stamped into the gold iridite plated "derby cap", i.e., CA 17084024, and 17152. I'm not sure if the CA means "California", the 8-digit number I assume is the GM part number, and I think that the 17152 translates to the 171st day of 1975, second shift. I did buy this part in the late 70's. Additionally, the body of the diverter is made of cast black plastic. I now know that the correct diverter for my car is a 7029199, so I have no use for this piece.

Can anyone tell me the true application(s) for this diverter? I'm assuming it's for a late '70s Corvette, but I'd like to know the exact application(s) so that I can offer it for sale to a fellow hobbyist through the Driveline. It's brand new, and hasn't been mounted on a car, so I'd like to see it go to someone doing an NCRS restoration.

GMPartsDirect (discount supplier) has it in their database for $76.90, but no application info, so it probably is still in the GM parts system, just call a local GM dealer and ask them to look it up.

The GM #17084024 diverter valve replaced the GM #17052772 diverter valve which replaced the original GM#7029199 used on your car.

The application of the GM #17084024 diverter valve is 69-72 Corvettes with A.I.R. and 350 cid engines (most 70-71 and some 1972 Corvettes did not use A.I.R.).

The GM #17084024 is a fully FUNCTIONAL diverter valve for the above-referenced applications and may be a workable substitute for other applications. However, it is NOT configured, at all, like the original valve. The 17084024 valve is primarily constructed of high impact, black plastic.

If the number series which you reference is a date code, then it would have top represent 1985, at the earliest, since this part didn't exist before then.

Addendum

Just to be perfectly clear, the GM #17084024 is a SERVICE-only replacement part. It was never used in PRODUCTION for any Corvette.
