checking a fan clutch
Hi 77vette,
To check the fan clutch when the engine is cold and not running, you should be able to spin the fan blades freely with no resistance. After driving the vette so it heats up, the fan clutch should engage (temperature activated) and be firmer, turn the engine off and it should turn with resistance, but not spin freely.
As I also understand, when you turn your engine off (hot) with the hood up, watch the fan blades, they should spin several revolutions before stopping. It should not stop instantly when the engine is turned off. Will someone please correct me if this theory is wrong?...
Hope I was helpful.
I switched to a flex fan and cured my running hot woes, and I had done everything you had previously done to yours, also. You could check out the "Flex Fan" post in the C3 section for my findings.
