I've been reading a little about my fan clutch, I have the newer plastic blade type fan but I'd like a little clarification about how to test to see if it's bad. I'm sure mine is fine but I'd like to see if mine is on it's way out, my fan has always spun down when the engine was hot, it never stopped with the motor, nor in 1-2 Revolutions, but never gets over 80*c what do you think? should I replace it or just keep my eye on it?

To test the clutch (after making sure the radiator is clean &
hot), get the engine to 100C or higher, and kill the engine while
watching the fan. It should stop immediately, or within 1-2
revolutions. If it spins 5-10 times, it was not engaged. Compare this
to how it acts a warm or cool (40-80C) engine. And yes, the fan does
do a lot at freeway speeds, the ram air effect at 70mph IS NOT enough
to cool the engine with a bad fan clutch.
