  • The Difference Between Cooling System Expansion Tanks and Overflow Tanks

    Comments ON 2016 April 19
    by therealcoleq

    It’s pretty common to hear people talk about expansion tanks and overflow tanks interchangeably. The fact is that they work very differently, and we’re going to explain the difference!

    As the name implies, an expansion tank expands the coolant capacity of your vehicle’s cooling system. The coolant in the tank is part of the recirculating system, making the system work as though the radiator tanks were larger or the engine held more coolant than it really does. Continue reading

  • How Radiator Cap Pressure Affects Cooling

    Comments ON 2013 August 20
    by therealcoleq

    Flex-a-lite-radiator-capOne of the Monday Tech Quizzes that we posted the Flex-a-lite® Facebook page was about radiator caps, and whether or not the pressure of the cap might help solve an overheating problem. As we tried to formulate a short answer for this question, we were reminded of how complicated the topic really is. So we decided a post on our blog would be the best way to provide useful information on the topic.

    First, the radiator cap is an important part of the cooling system. It is designed to hold a certain amount of pressure inside the system, and to release the pressure when it exceeds a pre-determined level. Why do you want pressure in the cooling system? Continue reading

    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

  • 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

  • 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.

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

    by admin

    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

    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. Continue reading
