The electronic thermal clutch fan is responsible for controlling the operation of the radiator cooling fans of a vehicle. For examples, A bad or failing electronic thermal clutch fan may not engage properly thus disabling the radiator cooling fan operation with in a vehicle causing it to overheat. When a vehicle is towing a heavy load under extreme cold or hot weather conditions, the electronic thermal clutch fan may not operate up to the maximum efficiency for cooling the engine properly. The efficiency of the electronic thermal clutch fan is normally tested at the standard room temperature. When a vehicle is towing a heavy load in a higher elevation, the electronic thermal clutch fan may not operate up to the maximum efficiency. The efficiency of the electronic thermal clutch fan is normally tested at the sea level, wherein the elevation is not a factor and tested under non-extreme towing conditions. As a result of those examples, the engine may result in overheating and lead to more serious mechanical issues as the operator of the vehicle may be unaware of the failing or inefficient electronic thermal clutch. Furthermore, it also affects the air conditioning, transmission cooling, the engine oil temperature, and radiator temperature.

More specifically, the present invention provides a direct drive and non-electronic hub between a fan pully of the engine and a radiator cooling fan assembly of the vehicle thus eliminating potential problems such as failing electronic parts, failing mechanically coupled parts, and inefficiency that are currently present within the electronic thermal clutch fan and the control module. As a result, the present invention is able to eliminate engine overheating in relation to a bad or failing electronic thermal clutch fan, higher elevations, extreme hot or cold weather conditions, racing, or towing. The present invention also optimizes the efficiency of the air conditioning process, transmission cooling process, oil temperature, and the radiator temperature thus resulting less thermal stress on the engine.
