I am concerned about running hot at idle with my recently rebuilt L-79 engine that has had its initial break-in but has not yet been driven to complete the break-in.
After about 30 minutes idling during an 80 F day the temperature gauge was reading about 195F and my IR gun was reading 210F on the thermostat housing.
My fan clutch was purchased from thepartsladi on EBAY and was listed for 1960-1970 Corvettes and is a reproduction of the 3916141 R service replacement fan clutch .
This 1990 article states that the fan clutch is likely operating at a maximum friction of 210F (for 1968 and later Corvettes) and should be about 190F for 1967 and earlier Corvettes.
Since this article is now 35 years old I thought it would be a good idea to check if members still recommend this adjustment.
For my fan I plan to rotate the spring counter clockwise 180 degrees and set it into the opposite slot. Is this correct ?
Also, I noticed that the CC version has hot glue where the spring drops into the slot. Do you think this is just for shipping ?
