Never used the Ultra cool myself. I have installed the regular oil coolers with no problems and good results on my last three bikes.

Thanks,
I have a Fatboy 2011 96' and wonder if installing the stock HD 6 rows cooler or the ultracool with 14 rows and fan .

Is your regulatr oil cooler from HD ? does it have a fan ? did it make any change ?

Thanks,Ilan

I have the regular oil cooler from HD - no fan. For my riding style it does make a difference in helping to keep the oil temps cooler. My experience shows that a cooler alone was OK - but best results are when used along with a good tune and synthetic oils.

I have the 6 row cooler from HD with the thermostat, and it dropped temps by ~30°F (17°C).
Highest I saw oil temps before the oil cooler install was 250°F.
Now it rarely goes above 220°F.

From what others have said on this forum, that is typical.
You'll find a 20°F - 30°F (10°C - 20°C) drop in temperature by using the HD/Jagg oil cooler.

Thanks Kainman,
25F is typical drop .
Fan will probably work better in heavy trafic or slow ride .

I've thought about that Ilan, but then you also have to consider the issue of keeping moisture out of the electric fan, thus ruining it.


Do you know what kind of oil temperatures you are running now? And are you using regular oil or synthetic?

Be careful with interference fit with the front fender. I just had a guy this week that had one that company said would work on a '91 Ultra ... no friggin way ! Mounts down under the regulator mounting bolts and sits forward of the regulator 3 inches ! Think about that.
I showed the guy that wants it installed and said I'd put it on but I ain't responsible for damages ! He nixed it ... goody goody !

This Ultracool fan cooler is mounted above the regulator between the frame bars .
I do not see anyone says he has it .

Jagg is supposed to be one of the best oil coolers. Keep in mind, you're using the oil
to cool the engine. Usually not a big deal with stock motors, but when you start doing
things like putting more cubic inches in and running them harder, it becomes something
to think about.

250F with HD oil cooler

I installed the HD 6 rows oil cooler . most of the rides in open road it will be 200-210 . but when riding in hot weather about 95F 35C , at slow drive or on hill with curves , it came to 250F . but this is rare .

Is it normal ? is anyway to add any item to direct more air flow ?

250F even with HD 6 row oilcooler

Installed recently HD 6 rows oil cooler on my 2011 Fatboy .
Seems it works on open roads and temp is about 200-210F

But riding in hot day 90-95F at lower speed on hill with curves will bring the oil temp to 250F . this is rare . is it normal ? I am using semi synthetic oil .

Is any item in the market to direct more air flow to the engine/cooler ?

Tx,Ilan

Very little if at all. To provide much cooling, there needs to be air flow. No matter where the radiator is located. Not sure why you're worried, 250 isn't that high, but if it really bothers you, add a fan to circulate air when not moving enough to get good air flow.
