Len - I hear ya.

Dr. Brad - You don't necessarily have to "go to the mountain" to test the fan clutch. If it's worn, it's worn and everyday driving will show this.

Do drive the car 'til it's good and warm, then pull over. Leave it idling. Pop the hood. Close front door - leave window down. Reach in and turn off car and quickly look fwd. to engine bay. Fan should not be spinning.

I find it helps to do this test with a second person sitting behind the wheel. Have then shut off the motor while you watch the fan blade. If the engine is fully warmed up, the fan should stop spinning as soon as the engine is shut off.
