The cooling fan assembly is an essential part of your vehicle's cooling system. It must complement the rest of the cooling system by efficiently cooling the radiator and/or condenser. Failure in the cooling system result in engine overheat and may lead to permanent engine and/or transmission damage. TYC cooling fan motors use high grade ball bearings, magnets and carbon brushes that allows them to be rated for 2000 hours of trouble-free operation. To ensure durability, each cooling fan design is run through tests like: Corrosion resistance, endurance, moisture, torsion and, vibration.
