Looseness

Check a loose fan clutch assembly for wear. Replace the fan clutch as necessary.

Under various temperature conditions, a lateral movement is visible at the tip of the fan blade. About 6.5 mm (1/4 inch) maximum lateral movement, measured at the fan tip, is allowable. Replacement of the fan clutch is not necessary.

Make sure that the fan blade is installed properly. If the fan is installed incorrectly, it will cause an overheating problem.
