Anyone try this kit : the oil cooler fan
I read some threat about it but no one tell his opinion is it good or bad, & some guys said that it wont fit the 09&up modle
I like the idea but is it ture that it decrease the temp 20-40F

What I see in the video is the temp of the outside of the cooler drops very fast, but this doesn't mean that the temp of the oil inside the cooler follows the same curve.
I don't believe a fan would make the oil temp drop by 40F in the first place and certainly not in 60 seconds.
I have an oil cooler and an oil temp gauge on my Ultra. The oil temp doesn't drop this fast (and not this much either) when the bike moves after being idling for a long time, like in stop and go traffic and there's definitely more air hitting the oil cooler when the bike moves at 60-70mph than when a small fan hits it.
When my oil temp reaches 220F after riding at low speed in heavy traffic, it take 10-15 miles at 70mph for the oil to go down to 200F and the temp stabilizes at 200F even if I keep moving at the same speed. No way it'll go down to 140F.

I have them. (still run) Got them in preparation for our trip to Sturgis in '09. Still overheated. They just don't move enough air to stop you from overheating in traffic. Get the LeNale fan or better yet http://www.wardspartswerks.com/ who is a sponsor on the site.

The Ward FCS cools the heads, not the oil directly, and does a remarkable job of controlling temperatures at that critical spot where most engine heat is generated. Oil temperature still climbs but not to the previous levels and they recover more quickly once you get moving again. I believe that's because the oil cooler doesn't have to fight against a super-hot head once air begins flowing through the cooler again.
I have temps pretty well under control now with the oil cooler and FCS, and likely won't make another attempt at adding fans to the oil cooler. OTOH it certainly wouldn't hurt if I could find fans that were durable enough in that environment.

I've rigged oil cooler fans on three different occasions and found them to slow the increase in oil temperature but not halt it completely--and they certainly don't cause oil temperatures to decrease while idling. They were somewhat useful but not a panacea, as 05 Ultra observed, and IMO not as good a solution as the engine fans sold by Jason Ward. Admittedly, they're also a lot cheaper. When the last pair of cooler fans failed about six months after installing them I didn't replace them.

I assume you mounted the fan behind the cooler, as I don't think there would be enough room to clear the fender when the forks were compressed if mounted in front. My problem is that I have <1" of clearance to pull the VR upward, and that wouldn't be enough if pulled straight up on axis with the bolts. The filter adapter on the cooler restricts further movement, but I could get more distance if the VR was tilted forward and up. It's pretty tight in there and I would still have to worry about the fender if the VR moved too far forward.
Here's a photo of the Jagg for the '99-'08 bikes, and I assume they've remounted the VR and tilted it almost 90° with the cooler relocated on top of it. I'm not sure what this assembly bolts up to. I wonder if their mounting hardware would work with the HD cooler, under the delusion they would sell it separately.

SPAL! It's an ATV waterproof fan, it will lower your oil temp when you come to a stop and it won't fail, been running the same fan for about 4 years. The 4" should do the trick, the 5.2 was a bit challenging to squeeze in there, BTW I used a puller, without fan 15 degree drop when moving, with fan 25 degree drop always. It pretty much stays on once it comes on and it dramatically improves cooling while moving. Look part way down the page here

I've got the Baker +1.5 oil pan installed on my 117 cu in 2011 Road King. Temps after my 117 build and +1.5 oil pan installed in 85-90 degree weather were between 239-241 on the highway. I really don't think the oil pan did much in lowering oil temps, maybe a few degrees or so. The real difference in lowering my oil temps came with the Jagg Fan Assist Oil Cooler I installed which lowered the highway temps to 231 degrees and stabilized oil temps to no higher than 231 degrees in traffic and stop and go driving.

About halfway down this page you can see my fan assist cooler project.
I find if I see I'm going to get stuck in a high heat, idle situation, I turn on both fans well in advance of needing them. Easier to keep it from overheating then trying to cool it after its already started to happen. When my LeNale fan craps out (as I guess they all do) I'll be stepping up to your kit.
Great work there.
