Oil Cooler : V-Twin Forum: Harley Davidson Forums

Multi part Question here! At what temperature does the oil cooler start passing oil on the Ultra Classic and Tri Glide Models? Is the temperature adjustable for when the thermostat starts passing the oil through the cooler? Went to a 10 row Jagg and for hot weather in traffic would like to know if I could get the oil cooler opening up a little sooner if the temp is over 225 before the oil cooler is allowed to pass the oil! I know the cooler don't do much good stalled in traffic but am planning on using a fan on the cooler off the accessory switch! The Tri runs hot, just brainstorming!

I may have allready answered part of your question ,but the cooler has a thermostat in it set to 185 degrees it is not adjustable..

What kind of temps are you seeing with the Jagg oil cooler?? Are you using the vertical or horizontally mounted oil cooler??? The 10 row???, or 6 row???

You would be better off with a SEST, or TTS and a proper tune to cool the bike down.

I like that idea.

Look at Buell's fan history; well we don't need the fan in action after the ignition is cut off, which made bystanders wonder what happened to the parked Buell.
Can a Buell-connaiseur explain what device ( at what T° ? ) triggered the fan ?

I too, like the big sky fan kit,but will they fit behing the Jagg oil cooler he already has???I know they will fit behind the HD oil cooler,but the Jagg is a little bigger!!! Is anyone running a Jagg 10 row cooler with the big sky kit with good results on a bagger??

Craig,

Big Sky recommends their fan with the Jagg. I bought one but haven't installed it or the cooler yet.

I am using the Jagg 10 row low mount! I got an honest 15 to 18 degrees lower in the wind. No more than 5 at idle until I used the fan. With the fan, if I turn it on before the temps go past 270 I get around 6-9 degrees lower.

It does not seem to climb past 280 or 285 if I use the fan! Have not richened up the fuel yet, hoping for a little relief here also.

I kick in the parade fan and the EITMS does not kick in, hoping I am not just blowing on the air temp sensor in the head and tricking it.

No where in Tri State that I know of that can dyno a trike?

Called MOCO, they will warranty the SEST, now the SEPST, thing is all I get is a 2010 canned MAP, way to lean.

The MAP is all I get, dealer as most can't dyno a trike!

I know I need to richin up the AFR to around 13, 13-5 at idle range 900 to 1050, first MAP for just slipons don't even richin up the fuel.

TTS is the best but, how do you find a good tuner that can dyno a Trike?

I won't pay the 600 for a Dealer tune, they want to sell me the SEPST unit and tune, but it is dedicated to my Trike only. Probably would be around 200 per tune/MAP aferwards but I don't intend to mod past the slipons. It is just a canned MAP not a tune, not close enough or can really know what I am getting since it in on their computer, not mine. Just looking for the cool down.

I too will be using the Jagg 10 row with the Big Sky Fan Kit on my build.I was initially concerned about fitment issues with the 10 row & Big Sky??? I guess it fits fine??? I will be purchasing the Big Sky with the thermostat for a twin cam.

That's funny when I called the guy(Milan) at Big Sky he wasn't even sure if it would fit with a Jagg 10 row???

Coupe, quoting from the Triglide Service Manual Supplement (PN 99601-09 <Note the year) Section 3.4, page 3.5:

"The flow of oil to the cooler is controlled by a thermostat in an adapter located between the oil filter and the oil filter mount."

"Under pressure from the crankcase, engine oil flows from the crankcase oil filter mount into a passage in the oil cooler adapter. The thermostat is located across the supply and return ports of the adapter and consists of a temperature sensitive element compressed between a spring and a threaded plug."

"When the engine oil temperature is below 200*F (93*C), an open thermostat allows the largest percentage of engine oil in the supply port to pass through to the return port and then to the oil filter. A smaller percentage flows through the oil cooler."

"When oil temperature exceeds 200*F (93*C), the thermostat closes and all the oil flows through the supply hose to the oil cooler."

"The oil circulates through the finned tubes of the cooler to dissipate heat and returns to the oil cooler apapter through a return hose."

"The oil is then filtered before returning to the crankcase."

"NOTE: Regardless of whether the thermostat is closed or open, oil is always pressurized in the oil cooler adapter, the oil cooler supply hose, the oil cooler, and the oil return hose."

The stock thermostat is apparently not adjustable anymore than the old radiator thermostats that we grew up with were. You might be able to find a replacement that activates at a lower temperature. As an alternative, if you can find a cheap stock duplicate (to preserve your options to restore the OEM thermostat), you might try soldering the sucker closed and run through the cooler all the time!

Hope this helps a little bit, anyhow. Can I pour you a cup?

Thanks Trils, I believe the Harley needs to get the oil warm fairly quick, just trying to come up with something that opened a little quicker to the cooler. I found a way to get that fuel to 13.8 across the RPM band without that expensive tune, at least until the warranty runs out...thanks again!

They got the 09's done but are in the progress of doing an adapter for the 2010's. I belive this will hold me until I can find a good tuner who can dyno a Trike.

Catomectomy, Jagg 10 row with the fan, Lanele Fan for the Heads, Richin up the AFR on the cheap...Synthetic oil...won't know until July, August but I feel I have got it under control.

I know a good tune and a set of 255 cams is the final answer but hate to break into it right now. I really picked up some low end torque and a lot better throttle response with the catomectomy...stock mufflers. I believe I am dumping some heat quicker now also with no stuffin in that headpipe holdin it back.

I would take a cold beer, hot beverage after chasing this heat problem ain't makin it, a cold one would go good right about now...dang quick post no beer Icon!

catch ya later amigo!
