Review on πŸ”₯ Enhanced Performance: Flex-a-lite 485Direct-Fit Black Magic X-Treme Electric Fan for '87-'06 Jeep Wrangler by Chuck Chen

Revainrating 5 out of 5

This fan will blow your mind and so will the heat.

I rebuilt the cooling system on a 2000 Wrangler 4.0 Sport. This included a high flow water pump, high flow thermostat housing, thermostat (195 left) and some hoses. I left the OEM heatsink last to swap out if needed. This turned out to be unnecessary due to the 485. This was done before the original cheap fan was used, so I think this rating is more legitimate given that both fans in the test had these benefits. I started with a cheap fan from AZ with 1100 CFM (at best). He could barely stay under 210 when moving. Downtime was a different story, especially when the air conditioning was on. And of course, once the heat index went up, he was simply and understandably overwhelmed and useless. Now it's leaning against a wall in a garage to be reused or disposed of. A 485 Black Magic fan enters. The processing quality is excellent. Housing (and its general design), blades and mount. Everything about him seems solid. It is important to note that for use with this fan I purchased a Flex-a-lite 31165 variable speed control module which can be found here: Flex-a-lite 31165 variable speed control module combined with the control module is unbelievable. .This fan is very, surprisingly simple to keep the coolant at any desired temperature. This includes the firing at over 106 degrees that took place during the restoration. On this day the car was in the sun for a total of over 4 hours with AC power. Burnt out 1/8 tank or more, dial everything in to make sure all settings are set. Model 485 with soft start and variable speed module worked perfectly. It lowers the temperature VERY quickly until it reaches the set point. I used an ODB2 engine coolant scanner and a new variable voltage gauge which I added to the fan circuit for fine tuning until I got exactly what I wanted. For reference. , you can find the scanner here: OBD2 Scanner, Seekone Professional Car Auto Diagnostic Code Reader OBDII & CAN Engine Engine O2 Sensor Systems EOBD Scanner Tool for all vehicles with OBDII protocol since 1996 (updated SR860) Temperatures are now independent of my expectations under control hot hot environment. At full power, the 485 is surprisingly quiet in the cabin and even too open outside. This thing moves a huge amount of air. You can feel a lot of heat from the block while standing around the hood. As mentioned earlier, my cooler is an OEM. Any aftermarket heatsink with less resistance (but better cooling performance) will do even more good. Thanks to the 485, I no longer have to think about replacing the cooler at this point. Thanks to the control module and how I connected it. The system now resembles a modern car. No more mechanical clutch taking away some of the grumbling. The fan runs independently of the ignition and reduces the speed at will after switching off. It's only a matter of time to make sure it lasts. To help, I made a place for the control module behind the glove box (it wasn't easy). I did this to protect the module from the environment. It's weather resistant, but far from being weatherproof. After all this work, the last thing I want is a faulty or corroding module because like everything I've seen, it's under the hood. like a steak. Fan + controller + other including additional cable (10 + 12AWG) are not cheap. However, the boiling block and the associated system damage easily outweighs this cost. With the amount of air the 485 moves, it will likely handle most applications. I don't know if it can support a Baja truck roaming the desert, but otherwise I'd shell out the money, it'll do the job you need.

Pros
  • Easy to read control panel
Cons
  • Lots of stuff
