TYC cooling fan assemblies are designed to be equivalent to OE in performance, validated through air-volume testing that simulates cooling ability. Each unit is a complete assembly with motor, fan, and shroud to simplify replacement. To ensure durability, each cooling fan design is run through a series of tests, including endurance, torsion, and resistance to vibration, moisture, and corrosion. In addition, each unit is subjected to a power-on test before leaving the factory to ensure functionality.
