Application note: This radiator was used on 1969-72 small block Corvettes equipped with factory installed options. These options could include an automatic transmission, air conditioning, or special engine options such as LT1 and L46. Base cars (with no options) used a smaller radiator with the separate surge tank.(Click Here)
The most powerful cooling combination available. This radiator and fan pairing provides the highest heat rejection package ever created. A traditional DeWitts Pro-series aluminum radiator with two rows of 1.0" wide cooling tubes provides a 25% increase in radiator cooling performance alone. Then mate an industry exclusive 500-watt SPAL brushless fan to the radiator using DeWitts aero inspired injection molded shroud and you have unmatched cooling power and performance.
The new SPAL brushless fans were developed and designed with cutting edge technology, high energy ferrite magnets, and a state-of-the-art sine wave sensorless drive. These motors reach more than 82% electrical efficiency, placing the 500-watt power range products among the most efficient motors anywhere. The result is high air-side performance at minimum electrical load. These brushless motors are fully sealed to be IP68 and IP6K9K compliant and can operate in the presence of many aggressive or hazardous substances.
