Black Magic Xtreme Direct-Fit Electric Fan for 1987-2006 Jeep Wranglers with Adjustable Thermostat Controller, Puller Fan (485), Car Accessories, 15 Inches

I rebuilt my 2000 Wrangler 4.0 Sport cooling system. This included a high-flow water pump, high-flow thermostat housing, thermostat (stayed 195) and several hoses. I left the OEM radiator as the last thing to change if I needed too. It turned out unnecessary due to the 485.This was completed prior to using the initial cheap fan, so I consider this review more legit as both fans had these advantages during testing.I started off with a cheap fan from AZ running 1100 CFM (at best). It was barely able to keep below 210 when moving. Idle was another story, especially with the AC on. And of course soon as the heat index rose it was simply, and understandably, overwhelmed becoming useless. It's now leaning against a wall in the garage destined for re-purpose or the trash.In walks the 485 Black Magic fan. The build quality is outstanding. The shroud (and its overall design), the blades and fitment.Everything about it feels solid. Importantly I purchased the Flex-a-lite 31165 Variable Speed Control Module for use with this fan, which can be found here: Flex-a-lite 31165 Variable Speed Control Module The actual performance of this fan in combination with the control module is incredible.This fan very, shockingly easily keeps the coolant at whatever temperature I want. This includes a roasting 106+ degree heat index scorcher that happened over the course of the rebuild.On that day the vehicle sat idle in the sun with AC blasting well over 4 hours total. Burnt 1/8th or more of a tank dialing everything making sure all aspects set.The 485 with soft start variable speed module operated with perfection. It brings the temperature down EXTREMELY fast until it reaches the intended setting.I used an ODB2 scanner monitoring the engine coolant, and a new variable voltage dash light I added to the fan circuit to fine tune until I got exactly what I wanted.For reference, the scanner can be found here: OBD2 Scanner, Seekone Professional Car Auto Diagnostic Code Reader OBDII & CAN Vehicle Engine O2 Sensor Systems EOBD Scanners Tool for all OBDII Protocol Cars Since 1996(Upgraded SR860) Now the temps are under control beyond my expectations regardless the hot broiling environment. At full blast the 485 is surprisingly quiet from inside the cab, and even outside too frankly.This thing moves a MASSIVE amount of air. You can feel a LOT of backwash heat from the block when standing around the hood.As mentioned my radiator is OEM. Any after-market radiator with less resistance (but better cooling capacity) would see even more benefit.At this point due to the 485 I no longer need to consider changing the radiator.Thanks to the control module and the way I've hooked it the system is now like a modern vehicle.No more mechanical clutch robbing a bit of grunt. The fan runs independently of ignition, ramping down after shutoff as it sees fit.It's now just a matter of time to see its longevity. To help I made a spot for the control module behind my glove box (this wasn't easy).I did this to protect the module from the environment. It's weather resistant, but that's a far cry from weather proof. After all this work the last thing I want is a failing or corroding module because it's under the hood like everyone else I've seen.This also made it nice to dial in during the scorcher sitting in the passenger seat with AC instead of outside roasting like a steak.The fan + controller + misc including extra wire (10 + 12AWG) isn't cheap. However, a boiling block and resulting systems damage easily outweigh this cost.With the amount of air the 485 moves it'll likely handle most applications. I don't know if it could maintain a Baja truck ripping across a desert, but short of that I'd lay money it'll do the job you need.

I've got a 400 Chevy SB in my 1991 YJ.(worst choice on the planet BTW) I was constantly having problems cooling it down where I live, in the high dessert of Eastern Oregon. I had ended up putting a factory Clutch fan as the only way I could get it under control. However it was worthless on the trails. So, I bit the bullet and got this electric fan installed and wired hot off the battery. The only issue I had with the install was that the fan hung below the radiator by 2 inches or so. So, to get the most draw through the radiator I ended up mounting a piece of flat across the gap, I haven't had any cooling issues since. The fan will run for 20 to 30 seconds after i shut the engine off and sometimes kick on a second time for 15 seconds or so. At the time that I installed the fan I also installed an Oil Cooler and Tranny Oil Cooler which I'm sure they also help cool it down as well. I would recommend if you have installed this fan and you rig is still running hot look into additional coolers. If I was able to cool down this 400 I'm would think you can cool down anything. Just thought I'd share my findings.

I bought this fan and installed it on my Jeep tj. It works very well if you are just sitting at idle but at any speed above 40mph it restricts airflow to much and the engine starts over heating. I returned the fan to flex a lite and was given a full refund. 4 stars for the build quality of the product and the refund. BUT this fan is NOT going to work well at freeway speeds.

I had purchased and installed this electric fan with the expectation of having cooler summer running temperatures and better fuel economy - neither of which were achieved - the electric fan worked well in slow, stop n go, city driving and such - but at freeway speeds the shroud must block too much airflow as the fan opening is smaller than factory & at freeway speeds I ran about 10 degrees hotter. The electric fan with the install kit fit well and installed fairly easily. However, the temp control was tough and tricky to setup as the Flex a lite temp control is cheap and cheesy & I wasn't willing to spend more $$ for better temp control - additionally the electric fan did not result in getting me better fuel economy - in the end I put the factory fan & shroud back on & sold this one on Craigslist - the factory setup really works best

The fan was for a Jeep Wangler. I had a previous Flex-a-lite fan that produce a lot less volume. This fan is much better and I am very pleased with it. The instructions were good until I got to step 8. In order to put the thermostat temperature sensor in the radiator as instructed in step 8 I had to remove the fan assembly which was step 1 through 7 install the sensor then reinstall the fan assembly. Sounds easy but it took an additional hour or two to do it. So before installation think about how the sensor will be installed in your vehicle before mounting the fan.

It is nice fan make my jeep wrangler tj 2004 temperature go down i leve in hot country only I heat the muddle not go quality. It com broken.

unfortunately this did not work for the setup on my fi stroker wrangler tj with ac, intercooler, and winch in front. will have to install the mechanical clutch/fan as it performed better on the road for my application. crawling on the trail this fan would do good i think... but first i need to get it to the trail.

It pays to buy the best. This fan is exactly what it is advertised as. I have been using it on my Jeep as the primary fan most the summer in 100+ degree heat and traffic. The thermostat module is working well also. Verfy pleased
