Overheating? Another perspective ...

[427]

I'm not an expert (nor do I play one on TV), but the info here may be another possible solution to running hot. I fully realize there is no substitute for an efficient radiator, proper tune/timing/vacuum, correct gauge/sender readings, etc ... But I rarely see mention of recalibrating the fan clutch.

I posted a reply in the C3 section regarding the fan clutch, I'll elaborate a little more for the C2 crew. Back in 1990, "Corvette World" magazine (no longer in print) published an interesting article regarding the fan clutch. They claimed the GM parts reduction program would yield an incorrect calibration for pre-1968 Vettes ... I'm not certain if this still holds true.

They also detailed the simple means of recalibrating your fan clutch ... Whether it be the thermostatic coil or the flat bi-metallic plate & plunger. By no means is this a miracle cure, but I have seen positive resultz from this procedure. I've scanned the article for your review: http://www.corvette.net/cac/fan_clutch

Ciao,

Very true.

The fan clutch was/is a great invention to cut down drag on the motor when you don't need it, and kick it in when things are getting hot.

An improper thermo kick could cause a world of headaches.

Thanks for posting.
