I know there are some related posts about it on here.. I have a friend that did it.. Works great.. and ADDS 1 QT OF OIL to your bike..

You drill, tap, and thread the bottoms of the crash bar.. (flat section where the tubes are welded) Screw in a hose barb on each side, and attach as you would an oil cooler..

I got the gage and adapter for my bike and attached as per Harley directions..

Not necessarily the best way as I think the oil pan way is better..

It's getting cooler here so I am not in a hurry till it's going into next summer.. I am sure I will have it all figured out for the best/simple way to do it..!!!

 

AHH.. I knew I would be getting that question... I have a "Whistler Crusader" installed where the air temp was... See Picture.. Thanks..

 

i have had a cooler on five harley's. to me it's the best money spent.any time you can drop temp's down you are doing alot of good for that motor.and yes there has been pro's and con's just like everything we all do.some belive in them some dont.

 

so as I see it to much heat shortens the oil life and hurts an engine in the long run to little and you don't evaporate the moisture a thermostatically controlled oil cooler helps maintain a lower oil temp there for helping in engine longevity so whats the harm .can you run without them sure sounds like it but if you want it to last longer keep the temps down then put one on ,I think and that's me that it doesnt hurt and gives peace of mind that you have done something good for the engine there's also small fans that can be put behind the cooler that helps that even when stuck in heavy traffic ,I used to work in NYC riding a MCY and our mechanic tried putting on fans way before there were parade fans even with coolers bikes would overheat now there are many options so Im going to try them Just for me peace of mind (its hot down here )

 

I guess another thing to factor in is the actual longevity the cooler will add vs. how long you plan to keep the bike. So if the motor would normally last until 100k, and adding an oil cooler ads another 30-50k to it, that's obviously great (just pulling numbers out of my a$$, there are not accurate representations!)

Then look at how long you plan to keep it. Even at 10k miles a year, that will take you 10 years to get to that point where you would need to rebuild. (I happen to average about 5k I'll admit, so that would be 20 years for me). How many people really will keep their bike for that long? I'm sure several would, but I would imagine the majority would be trading in/selling before that time most likely.

So unless you are a hard core rider and plan to keep your one particular bike for 10+ years, an oil cooler might not help all that much for most people. It won't really help with resale value either.

 

What I've read here are pros and cons to having an oil cooler. I suspect that the pros are guys who travel shorter distances at lower speeds, maybe get caught in traffic too frequently on the way to work, and can't just make a u-turn and go the other way. The cons, I suspect, are guys who spend more time at highway speed and don't suffer the inner thigh heat blast so much. Both are valid points of view, and it all depends on the style of riding you do and your personal comfort level with the amount of heat generated. I live in NJ and there is no place you can ride that won't force some flat foot time. I guess that puts me in the pro category, since I don't see the downside of reducing heat when sitting at a light or in traffic. I'm going to install the oil temp guage and the Jagg cooler to prolong the life of the oil and the engine. I've also just found out that the heat management system being touted as one of the great new features of the '09 touring bikes was available on my bone stock '08 FLHTCU. As much as I believe in heat reduction to extend life expectancy, I can't help wondering why the heat management system wasn't turned on automatically when I bought it new from my dealer. I'm going to ask them that question since it seems like a can't lose proposition. So obviously I'm missing something. Does anybody know what's the down side of shutting down that back cylinder, and what would be the cost to have it turned on now that the bike is a year old?

 

Read your manual.. As far as I know, you roll the throttle forward at idle to turn on and off the rear cylinder shutdown.. There maybe better and more accurate answers.. Don't think it costs anything though..:<)

 

BD, I have an 08 FLHTC and have heat management on. I like it. I have heard it uses a smidgen more oil when it is in heat management and, since your injectors are still working I suspect it may cut down on your MPG slightly. These are a small price to pay to have the rear jug cool off.

 

I recently put a jag 10 row horizontal on my 07 Ultra. Another benefit of cooler oil is less detonation, since Harley uses oil sprayed up underneath the red hot pistons to cool them down. Before the oil cooler I had mapped my AFR at 13.2 across the board with a PCIII. I still had some detonation as measured with my Daytona twin scan. I switched to a colder plug and that helped. After the oil cooler the temp went down at least 30 degrees, and I was able to go back to a stock plug, with slightly better performance. I am happy with mine, and I bought it directly from Jagg, and recommend them highly.

 

Newer FI bikes run lean resulting in higher operating temperatures. So another way to "cool" the machine would to richen the fuel mixture. Pick up a couple Hp, drop a mile or two mpg and reduce engine operating temperature.
