1995 Mercury Grand Marquis 4.6 83000 miles.
Since the clutch was replaced by a repair shop it is engaged for the first five minutes while the car is on fast idle,(67 degrees F ambient) makes a terrific racket, after about five minutes the clutch torque decreases and the engine sounds normal.
My question, What is the torque / temperature relationship of the fan clutch as the engine warms up ?
It seems the fan should be off during initial warm up.
