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

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

If you’re running a belt-driven fan, there are a few things you need to do in order to maximize the engine cooling that the fan can provide. It’s critical that the fan be positioned properly within the fan shroud and that there is just enough clearance around the fan blades. The first thing we want to make sure is that you actually have a fan shroud. If you rely on a belt-driven fan for engine cooling, a fan shroud is a must to pull the air through the radiator. Without a shroud, air will take the path of least resistance, pulling air from over and under the radiator instead of through it. Continue reading

PRODUCTS AFFECTED - The Flex-a-lite products affected by this fuse holder and circuit breakers are the Flex-a-lite electric fan model number 274 and fan/radiator combination model number 59274 sold from February 2014 to May 27, 2015. Products were sold through automotive retailers, mail order, and performance distributors. Date of manufacture can be verified by the UPC Code:
PROBLEM - Flex-a-lite has become aware that a fuse holder between the battery and fan control module was not supplied and that smaller circuit breakers should be used. 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.

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 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
