    Even with the expanding list of direct-fit Flex-a-fit® aluminum radiators from Flex-a-lite®, we know that there are even more configurations that you may be looking for. Maybe you're building a vehicle that we haven't engineered a bolt-in radiator and electric fan combo for, or if you have a custom need beyond what our direct-fit systems offer. Either way, you can still have a Flex-a-fit radiator with its patented cooling technology with our custom radiator options!

    Because we build the radiators in-house at our U.S. headquarters and manufacturing facility, we can perform quite a range of modifications to meet some very unique needs. Continue reading

    New products are always exciting! We have had a great response to the latest products that we introduced at SEMA, and now all of these new products are in production and ready to ship!

    What's new for this year? We expanded our line of direct-fit Flex-a-fit® aluminum radiators and electric fan combinations to cover some very popular vehicles. One that we're very excited to offer fits the '87-'01 Jeep Cherokee (XJ). People have asked us for a cooling solution for this application at nearly every off-road and 4x4 show we've attended in the recent past, and we heard them! Continue reading

  • How Flex-a-lite Makes its Flex-a-fit Aluminum Radiators

    We started making Flex-a-fit; aluminum radiators in 2006, and we decided it was time to give you the inside story on how they are made! The quality in the Flex-a-fit radiator we build for you starts in our Fife, Washington, manufacturing facility.

    Flex a fit detailFlex-a-fit radiators from Flex-a-lite; start with aluminum extrusions to create our patented sidetank design that uses internal and external fins. On the inside of the tanks, the fins perform as heat sinks by absorbing heat more quickly from the engine coolant through increased surface contact. The external fins increase the surface area threefold to transfer heat more effectively. We cut and machine the extrusions in-house, giving us the ability to do custom configurations in addition to our direct-fit and universal radiators. Continue reading

    How easy is to install a Mojave heater from Flex-a-lite®? You can do it on location at an off-roadding event! We met Phil Novold of Max-Bilt at the Moab Easter Jeep Safari, and he looked awfully cold in his '53 Dodge M-37. So we grabbed our video camera and caught on film how he added heat to his cool 4x4 in just a few hours. Continue reading

    If you own a Flex-a-Fit radiator, mounting a transmission or power-steering cooler to it is a breeze with Flex-a-lite radiator bracket sets. These kits include brackets and mounting hardware that use the patented "T" channel side tank design as the mounting location. This lets you easily move the brackets up and down, as well as eliminating the need for you to fabricate brackets or drill holes in your vehicle. Continue reading

    Some time ago, we introduced the Flex-a-lite Camaro SS project car that we were building with Duncan Speed & Custom in Lakewood, WA, to take on our 50th Anniversary Tour. Since then, we've put together a video that shows all of the work that Bill and Will Duncan did on the car to add performance and improve the appearance of the Camaro

    Why did we choose a Camaro to help us celebrate our 50th anniversary? At the last SEMA show, we introduced a Flex-a-fit® direct-fit aluminum radiator and electric fan combination for the popular 2010-2011 Camaro.

  • Introducing the Flex-a-lite 50th Anniversary Camaro SS Project

    We’re in the business of building performance cooling products. But every once in a while, we take it upon ourselves to build a performance car or truck to show off our wares. At the last SEMA show, we introduced a Flex-a-fit® direct-fit aluminum radiator and electric fan combination for the popular 2010-2011 Camaro. For the show, we outfitted an otherwise stock Camaro SS with the new system (you can watch the installation by clicking here). As we made preparations for our 50th Anniversary Tour, we decided to make some more modifications to the Camaro to complement the Flex-a-lite performance cooling system and help the car better fit in at the high-performance stops we have planned for the tour.

  • Choosing the Best Flex-a-lite Fan Controller for Your Vehicle

    Flex-a-lite fan controllers are much more than just a relay for your electric fans. They turn the electric fans on and off, most of them provide the ability to adjust the temperature at which the fans turn on and almost all of them take the place of relays that other brands of fans require.

    Many of our Flex-a-lite electric fans include a Flex-a-lite fan controller already, but the fans are also available without any controls.

    Here's a breakdown of what each of our controllers do so you can choose the one that's best for you... Continue reading

  • Flex-a-lite Makes Engine-swaps in '64-'69 Mustangs Easier with its New Aluminum Radiator Configuration

    We've offered the Flex-a-fit® aluminum radiator for both '64-'66 and '67-'69 Mustangs for quite some time. We've now expanded this line of direct-fit radiators to accommodate the popular 5.0-liter engine swaps (based on the '86-'93 5.0-liter engines).

    The original Flex-a-fit radiator for this application positioned both the inlet and outlet on the passenger side, just like the original. However, many people swap later-model engine into these popular pony car which requires the outlet to be on the driver side. The Flex-a-fit radiators are available both with and without a Flex-a-lite 3,000 cfm electric fan (part #160) pre-mounted from the factory. Continue reading

  • How and When to Use an Auxiliary Electric Fan

    Is your car running a little hot in traffic or when you're moving slow? Is your truck or RV running hot when you are towing up a hill during the hot summer months?? Consider adding an auxiliary electric fan to help your primary cooling system.

    At slow speeds or while sitting in traffic, you have very little or no ram air coming through the radiator, and typically, the engine is running at a lower rpm, which means the belt-driven fan isn't moving much air either. In some applications, this can cause the engine to run hot or overheat because there isn't enough air moving through the radiator.

    Adding an auxiliary electric fan to the front of the radiator can overcome this problem. Continue reading
