  • How to Gain Power and Fuel Economy

    The old adage that you can't have your cake and eat it too isn't always true. Diesel Power magazine did some testing and showed that when it comes to converting your power-hungry belt-driven fan with a Flex-a-lite electric fan, that you can gain power and fuel economy. You can read the whole article at dieselpowermagazine.com.

    The bigger and heavier the belt-driven fan, the more power you're going to free up. And you'll also see an improvement in fuel economy. The math here is easy: it takes more energy to spin a belt-driven fan than an electric fan. Another benefit of converting to a Flex-a-lite electric fan on your diesel truck is quicker warm-up times. That's like having you cake and eating it too, plus a side of ice cream!

    You can find more information on the Flex-a-lite electric fan for '03-'08 Dodge Ram trucks with Cummins turbodiesel engines by visiting flex-a-lite.com.

  • How We Would Hot Rod Santa's Sleigh

    Christmas is upon us, and in between trying to finish up production details on next year's new products, our minds have wandered into wondering about things. Things like how long is the naughty and nice list? How does Santa travel around the world in one night? We track him every year on the NORADsm web site, and we still don't get it. And why Mrs. Claus doesn't join the big guy for his annual present-delivering trip around the globe? We think it might be because it's too darn cold in that sleigh! Continue reading

  • Radiators: Aluminum vs. Brass

    11 Comments 2010 March 30

    There is an age-old debate about which material is better to make radiators from:  brass or aluminum. Most people focus on the radiator core design when choosing a radiator - how many tubes, tube size, how many fins per square inch, etc. - but the core is not the only part of the radiator that can cool. The sidetanks hold more of the cooling fluid than the core!

    Just about every high-performance vehicle you see in car magazines has an aluminum radiator. So you might assume that aluminum has the best cooling properties. That actually isn't true, and we'd like to share some facts and test data that compare aluminum to brass, and even to composite radiator sidetanks. Continue reading

  • Which is Better - an Electric or Belt-driven Fan?

    8 Comments 2010 February 27

    This debate is as old as the electric fan itself. We manufacture both, so we're pretty unbiased on this topic. In fact, we created the first high-performance belt-driven fan in 1962, and we were the first to introduce an aftermarket electric fan to the U.S. in 1978.

    We'll jump right into the heart of the matter: An electric fan is the better performance solution, freeing up maximum horsepower and mpg. But it's not always the better cooling solution. The full answer to this question is that both electric and belt-driven fans have their place. Which one is better depends largely on the specific application. Continue reading
