UltraCool Fan Assisted Oil Coller for Softails

I spent yesterday installing an UltraCool oil cooler that comes with a water resistant fan on my bike. This is a very nice unit and once the bike hits 160 degrees the oil will flow through the cooler. The fan turns on at 210 degrees and goes off again once the oil goes back down to 190 degrees. This system takes oil cooling one step further than any other cooler on the market. Your typical standard oil cooler has a thermostatic switch that opens the cooler at 160 degrees. That is it. There are no other cooler that have a fan built in to help keep the oil cooler thus most coolers cool the oil about 10 degrees. The UltraCool cools the oil 40-60 degrees due to its well thought out design.








The unit is perfect in every way, although I chose to wire it a bit differently than was shown in the instructions. In the instructions they have you run all the power through the provided led (comes on when the fan comes on). I chose to not run the LED and wire it direct to my accessory wire (orange and white on right side of the tank).

The install itself was simple although it took a few hours to get everything done perfectly. I found a few small issues with the instructions as far as the order to install everything as well. Please take note.

The oil line clamps cannot(or are extremely difficult to) be tightened with the cooler in place so I measured and ran the oil lines and then took the cooler off to put the clamps to the oil filter adapter bracket. Once the lines were tightened properly I put the cooler back in place and ran the oil lines to the cooler itself and installed the provided clamps. The wiring was the last thing I did. They provide a nice PVC tubing to run the wires through for looks and protection also which is very nice.

Once the entire unit is installed, it fits perfectly. I am yet to ride the bike for long enough to test out the fan and such and see what temp it comes on at, but as soon as all the rain we have been having is gone I will and will report back. It is supposed to come on at 210 degrees, and once the oil temp drop to 190 degrees the fan turns off.

The nicest thing about this system is the integrated fan. A regular oil cooler only allows oil through the cooler above 160 degrees to cool the oil. The Ultracool does the same but takes this a step further. When the oil reaches 210 degrees, which it will, the fan will kick on and force more air on to the oil cooler cooling the oil flowing through the cooler much quicker. Once back down to 190 the fan will turn off. As stated above the fan is water resistant so no need to worry about rain or washing the bike.

The softail version has just become available and I believe this is the first one that has been installed on a customers bike. I can’t wait to get out on the open road in the heat. As a side note I will be going to Laughlin next month and that will be the true test of how well this cooler works. Temps regularly rise above 100 during mid day and I plan to be riding all day.

Thanks!
