With any advanced, multi-feature electronic device, there are opportunities for things to not always work correctly. The Flex-a-lite Variable Speed Controller (VSC) is our most advanced electric fan control module, and it has several features built in. The following video and guide will help you diagnose and troubleshoot issues if your electric fans are not functioning the way you think they should when using the VSC.
Most of the time, when we get questions from customers regarding the VSC, the problem is a wiring issue. The first thing for you to do when troubleshooting an issue is to check all of the wiring connections at the controller. Double check the routing of the wiring. Look for signs of excessive heat at the connections or frayed wiring. Replacing any wiring that looks suspect. Many of the problems that customers experience are simply caused by not connecting the large black and red wires from the controller directly to the battery. Continue reading

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.

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

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 dozens of 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

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'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 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

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
