INSPECTION

M1141002200103

.

Cooling Fan Check

• Check the blades for damage and cracks.

• Check for cracks and damage around bolt holes in the fan 

hub.

• If any portion of the fan is damaged or cracked, replace the 

cooling fan.

.

Fan Clutch Check

• Check to ensure that fluid in the fan clutch is not leaking at 

the case joint and seals. If fluid quantity decreases due to 
leakage, the fan speed will decrease and engine overheat-
ing might result.

• When the fan attached to the engine is turned by hand, it 

should have some resistance. If the fan turns lightly or 
freely with no resistance, it is faulty.

• Check the bimetal strip for damage.
