65 temp gauage

[Ronald C.]

during a recent chapter event i took a deduction for having a 66 temp gauge in my 65 corvette instrument cluster. now the gauage is ranged 0-240 per the manual. anyone have some in site into how looking at a guage you can differentiate it as 65 or 66? this instrument cluster has been with the car for teh apst 30 years i have ownded it.

Ronald -

Sounds like a judging error; the '65 gauge had a max reading of 240, with 180 at the center, and no color. The '66-'67 gauge had a max reading of 250, with 210 at the center, and small bands of yellow and red prior to the 250 mark.

Re: 65 temp gauage

during a recent chapter event I took a deduction for having a '66 temp gauge in my '65 Corvette instrument cluster. Now the gauge is ranged 0-240 per the manual. Anyone have some insight into how, looking at a gauge, you can differentiate it as '65 or '66? this instrument cluster has been with the car for the past 30 years I have owned it.

Your '65 Sting Ray SHOULD get an originality deduction for having the "wrong" year temp gauge. Why are you surprised? We need more information. Why does it have a '66 model gauge?

Possible explanation: Back in the day, with the owner complaints of "it's running too hot" on the L76 engines in 1965 Sting Rays with factory A/C, Chevrolet then put out a tech bulletin telling the dealers to remove the temp gauge and install one from a '66 Sting Ray. The '66 gauge, I have been told, has a higher maximum temperature reading.

But, why a '66 gauge reading a max of 240? I own a rare L76-engined (327/365hp) A/C coupe and I get very nervous running the car in hot Texas summers using the A/C. My stock '65 temp gauge keeps climbing and climbing and "where it will stop nobody knows". I always shut off the A/C (and turn on the heater!) before the gauge reaches 240 degrees.

It doesn't - he said it has a '65 gauge, not a '66:

"the gauage is ranged 0-240 per the manual."

Re: 65 temp gauage

The 1965 gauge (GM # 6401667) was discontinued in Oct. 1966 and replaced by the 1966-67 gauge (GM # 6402594) so if you bought a replacement gauge in Oct. 1966 or thereafter for a 1965 it would be the 1966-67 gauge.

Sorry, I misunderstood the problem. During NCRS Flight judging, if the judging team makes a mistake, then it is up to you to point this out to them. It is too late, now. -Clark
