Radiator Cooling Fan: Service and Repair

Fan Replacement

Tools Required

Removal Procedure

Notice: If a fan blade is bent or damaged, do not repair and use the damaged part. Replace a bent or damaged fan assembly with a new fan assembly. Using a fan with a different diameter, pitch, number of blades, or type of blade material may effect the cooling efficiency, performance and engine noise level.
