   So far so good. I purchased this product to replace my FlexALite fan controller (that is about 8 years old). Nothing is wrong with the Flex A Lite controller. Just thought the temperature sender in this product would be better to use than that capillary tube that needs to be inserted into the upper radiator hose.I don’t know why Derale uses such a HUGE temperature sender. 3/8″ NPT is very large. It utilizes a thermistor, which is extremely small, and they pot it into a brass fixture of that size. They could’ve used a 1/4″ NPT brass fixture instead.I had to purchase an inline aluminum radiator hose adapter to house such a large sender. I purchased that item online which was cast aluminum.I find it odd that Derale chose to “switch” the negative, or ground lead to your electric fan. Majority of manufacturers utilize a “switching” of the positive lead to your electric fan.Temperature adjustment is simple, with using a jewelers slotted screwdriver.

   It works perfectly fine and adjusts to exactly what temp you like the fan to turn on. I bought two because I also bought the Derale two speed fan thinking it would be best to use two controllers in case one failed. The problem I ran into is that the fan controller works off from the negative side rather then the positive side so I was only able to use one controller and am left with a one speed fan. Luckily I had built a custom made shroud so I only needed the low speed anyway. Now I have a spare controller in case the other goes out so I’m still covered in case I have a failure 🙂

   Installed electric fans on my truck and needed a method of turn on for them. This kit comes with all the parts necessary to turn fans on.

   I have been using this controller for a v8-swapped Jeep TJ off-roading rig. The wiring is clean, it handles the load from a single fan well. The sensor threads fit the aftermarket radiator in my Jeep, which is why I originally bought it. I have had a couple relay failures, since when I’m off-roading at low speed, the fan is almost always on for hours at a time. I replaced the relay with a heavier duty-cycle HD relay and that solved that issue. BUT, in my first unit, the control board itself failed in a year. It would not turn on the fan based on temp, only when using the A/C bypass wire. I bought the same piece again, since I like the function and I really don’t want to re-wire the whole system, build a new mount, etc. It was much easier to plug and play the new board and keep all my nice clean wiring intact. The second unit has now failed after three years. It will not turn on the fan based on water temp or with the override. If I unplug the harness and jump the ground across, the fan comes on. I find that life-span to be somewhat acceptable, with the level of abuse my wheeling rig gets. The unit is mounted under the hood on the inner fender, so there’s a fair amount of vibration and occasional splashing. Hopefully the third unit will hold up a little better. If this third one fails, I may bite the bullet and re-wire my fan with something a little more robust. If you’re not constantly smashing your vehicle over rocks, you may have better luck with this unit than I have.

   I’m on my second unit now. These suck. Derale customer service is useless. Left me stranded with no fan.
