TYC cooling fan assemblies are designed to be comparable to OE in performance, validated through air volume test that simulates cooling ability. Each unit is an assembly with motor, fan, and shroud to simplify replacement compared to working on individual components. To ensure durability, each cooling fan design are run through tests like : corrosion resistance, endurance, moisture, torsion and, vibration. Each unit goes through a quick power-on test before leaving the factory to ensure functionality.
