New Mojave Heater Kits and Accessories Now Shipping
Flex-a-lite recently announced three installation kits for its popular Mojave heater as well as slim-profile plenum, and now all of these accessories are ready to ship! These new products make it even easier for customers to add a powerful heater in compact spaces.
The Mojave installation kits include “Y” tubing connections, a shut-off valve, hose, clamps and grommets. Flex-a-lite offers three variations of the installation kit that make it easier to install the Mojave in place of a failed factory heater core, in a new installation where there wasn’t any heater previously installed and in UTVs that use smaller diameter connectors.

When 2,500 cfm isn’t equal to 2,500 cfm
We’ve had quite a few people question our advice when we recommend a 2,500, 2,800 or even 3,000 cfm electric fan for their hot rod or 4×4. They often tell us that they have a 2,500 cfm fan now and their vehicle overheats in low speeds or when they are stuck in traffic. A little more investigative work usually uncovers that what they have now is a basket fan, which leads us to this question: Did you know that 2,500 cfm doesn’t always equal 2,500 cfm? Read more…
Flex-a-lite Jeep CJ Radiator and Fan Combos Now Shipping!
Owners of ’72-’86 Jeep CJs know how hard it is to find a performance cooling system that is as capable and durable as their Jeep. That’s about to change as Flex-a-lite is now shipping its all-new, bolt-in Flex-a-fit radiator and electric fan combo for these vehicles! And there are configurations available to fit CJs with stock engines and also to accommodate the popular GM and Ford V-8 engine conversions.The core of this combo is a Flex-a-fit radiator featuring dual 1-inch all-aluminum radiator core that is hand-welded in the U.S. to the Flex-a-fit sidetanks patented “T” tank technology. The “T” channels offer a durable mounting system for the radiator, electric fan and optional oil cooler or expansion tank. The radiator core is protected while off roading because the electric fan is mounted to the Flex-a-fit sidetank and not through the radiator core. The Flex-a-fit system also eliminates the risk of the belt-driven fan contacting the fan shroud when the body and chassis flex while off-roading. With this latest introduction Flex-a-lite now covers thirty years of Jeep CJs and Wranglers. Read more…
Why We’re Still Makin’ it in the USA
You may have seen the popular posting on Facebook called, “Christmas 2011 – Birth of a New Tradition,” urging people to buy American. We like the basic message of thinking about different ways that you can use your Christmas shopping to help the U.S. while minimize the exporting of American dollars to other countries.

How to Install an Electric Fan Controller
Perhaps one of the least understood parts of adding an electric fan to a vehicle is installing and wiring the controller. The Flex-a-lite adjustable temperature controller turns the electric fan on and off according to the coolant temperature, and you can adjust where the fan turns on from approximately 180-240 degrees F. No relays are required if you use our controller with our electric fan. Wiring the controller is simple, and following our directions will give you years and years of trouble-free operation.

Keeping Your Jeep Wrangler Auto Tranny Cool

If you own a 2007-2012 Jeep Wrangler (JK), you already know how cool this vehicle is. But if it has an automatic transmission, it might turn out to be a hot vehicle. In fact, last year, 88,000 of them were recalled for potential automatic transmission overheating. The fix at the dealership is to install a trans temp warning light. If the light comes on, you’re supposed to park your Jeep and let it cool down.
We have a different fix that we like a lot better. The Flex-a-lite Part # 4118 transmission cooler more than triples the cooling capacity that a Jeep Wrangler should ever need. Our trans cooler is made in the U.S.A. and includes our unique Turbulators, which are inside the cooler tubes. These Turbulators increase the heat transfer from the fluid. Read more…
Flex-a-lite in Norway, Fjord Sure!

While most car enthusiasts have heard of Hot August Nights in Reno, we stumbled across the European version: Hot August Nights in Trondheim, Norway! While most visitors to Trondheim are likely to check out the Nidaros Cathederal, catch a concert at Rockheim or jump in a boat and explore the beautiful scenery along the Fjords, we were checking out Fords, Chevys and a host of other American hot rods and muscle cars at this great event.
Hot August Nights in Trondheim is organized by the American Car Club Trondheim and has celebrated cruising and the American car culture for years.
We even spotted one of our fans – a Flex-a-lite Part # 110 electric fan – on a cool Model A.
The event is going on right now (August 12-14, 2011), so we’re going to go speak the universal language of hot rods with our Norwegian friends. If you’re in the area next year, plan on attending!
Will Ram Air Burn Up My Electric Fan?
This is an interesting question that we get asked at Flex-a-lite from time to time. When you’re driving on the highway, will the ram air cause your electric fan to spin, damaging it? A lot of people argue that the fan becomes a generator when it’s spun by ram air, and they worry that this can damage the motor or electronic controller components. The answer is, no, ram air won’t burn up your fan or the electronic controller, and here’s why. Read more…
How Flex-a-Fit Radiator Sidetanks Provide Better Cooling
Did you know that there is more to the Flex-a-Fit sidetank design than the T channels on the outside? Sure, these make mounting the radiator, electric fan, overflow tank and other components easy, but they also provide a boost in heat transfer, aka cooling! Read more…
