On some V8 conversions, you will be able to retain a stock mechanical fan. If have located your engine correctly, you will have .5" to 1.5" of clearance between the fan and radiator. However, many variations require the use of an electric fan. In those cases, we offer a 16" Flex-a-lite puller fan. Includes all the necessary hardware for installing without bolting through the radiator, which can cause serious damage off-road. The temperature sensor and manual switches are sold separately so you can decide which you prefer. The fan has a rating of 1450 CFM and draws 10 amps. It is best to mount the fan slightly towards the passenger side of the radiator to prevent interference with the water pump pulley.
