For decades Flex-a-lite has included a terminal on its popular electric fan controllers to allow customers to connect an override switch to either turn the fan(s) off for water crossings in an off-road vehicle or to make ordering in the drive-through a bit easier, or to turn the fan(s) on for additional cooling which is handy for a race car in between runs on the track. This is in addition to the automatic function of the fan controller which turns the fan(s) on and off according to engine coolant temperature. Flex-a-lite recently introduced a new 3-way switch (part number 31143), though that lets you override the fan controller for both manual on and off operation! Additionally, the rocker switch is illuminating, with a red light indicating that you’ve manually turned the fan off, and blue to remind you that you have the fan in manual on position.

Have you ever wondered why we require the use of a Flex-a-lite® spacer with our belt-driven fans? The answer is simple: we saw the damage other brand spacers were causing to the star of the belt-driven fan! We can easily tell when one of our Flex fan or other belt-driven fans has been used with one of these off-brand spacers; it will leave the imprint right in the star. In fact, we won't warranty damage done to one of our fans if another brand spacer is used. Continue reading

Racers and audio enthusiasts were the first to use 16-volt battery for better ignition and audio performance, and they are becoming more popular. An electrical-system expert will tell you that a small variation in operating voltage will raise or lower the speed of an electric fan, which increases or decreases the airflow. For example, Flex-a-lite's part number 398 electric fan (16-inch Syclone S-blade fan) moves 2,500CFM in a 12-volt system, but increases to 2,700CFM in a 16-volt system. Continue reading

One 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

Most of the Flex-a-lite electric fans come with either and Adjustable Thermostat Controller our Variable Speed Controller. While we've done a segment on wiring them, one of the common questions we get is where is the best place to mount them?
That's going to depend on the vehicle, but Flex-a-lite owner and president, Lisa Chissus, offers some tips and guidelines in the video above.
There are a couple of things to consider when choosing a location:
- You will need it to be close enough to the radiator for the temperature probe to reach.
- You want to keep it away from extremely high heat. Typically, on the radiator support or high and forward on an inner fender panel is good.
- You will also want to mount it high in the engine bay to keep it away from road debris and excessive water that can splash up as you drive.
- Finally, they are water resistant, but not waterproof. Do not mount them in a way that allows water to pool up around the terminals.
Flex-a-lite fan controllers are designed to take the place of relays, and offer you the ability to adjust what temperature the fan or fans turn on at, ranging from approximately 160-240 degrees Fahrenheit. We match the proper controller with our fans to accommodate the amp load, and we provide either a fuse or breaker. If you want information about choosing the right controller for your application, check out this article.

Replacing a belt-driven fan on your engine with a Flex-a-lite electric fan can be a great way to improve power, fuel economy and even give you a quicker engine warm-up. But how do you choose the right electric fan for your application from the 82 different part numbers on Flex-a-lite.com?
The first step is to know what fits. We covered this in an article and video previously (How to Choose an Electric Fan). In this article and video, we're going to spend more time talking about the differences between the various fans that fit your application to help you get the right electric fan. 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

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

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 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
