FAN CLEARANCE GUIDELINES
Fan blade clearances are intended to allow for engine shift caused by engine motor mount wear, severe braking, engine torque, and fan loading or unloading resulting from fan clutch engagement or disengagement. These clearances are minimum guidelines and do not cover all installations. Not following these recommended clearances will not only void your fan warranty but can also cause damage to the fan and other engine and body components.
MINIMUM FAN BLADE CLEARANCE
To Front of Fan – Minimum of 1” (25.40 mm) Clearance Between The Leading Edge Of The Fan To The First Obstacle Forward. Caution Not Always The Radiator.
To Rear of Fan – Minimum of 1” (25.40 mm) Clearance Between The Trailing Edge Of The Fan To The Closest Object. Check FEAD Pulleys, Crankshaft Damper, Crankshaft Pulley Etc. For Possible Interferences
Blade Tip Clearances – Blade Tips (Ends) Should Be ¾ “ (19.05 mm) From The First Obstacle To The Sides. Caution This is Not Always The Fan Shroud. Check for Radiator Support Rods and Other Potential Contact Points.
