Thread: Mechanical Flex Fan Question

Tweet

It would be Better if you could go with a Larger 18" Flex Fan . But this 16" Flex fan will move a Lot of air . I have used many over the years . Make sure you use a fan Spacer to move the fan close enough to your radiator 2" is most Likely what you will need . I have a 14" Flex-a-lite Fan that I use on my Engine Test Stand with a 58 Chevy Radiator . It works well in keeping engines cool when breaking them in . Just stick with the S/S not the Aluminum Blade Type's or fiberglass .

Be real cautious with a flex fan as there have been more then a few instances where they have fractured. We went through this exercise on another forum a year or so ago and the consensus was - there are better choices, especially for a performance engine. What happens is that while flexing, the blades are subjected to high cycle fatigue, eventually launching a blade through the hood (that one I've seen), radiator or hose
