Jagg Fan-Assisted Oil Cooler Kits 751-FP2600

I took my time installing this onto a 2003 Arlen Ness custom chopper with a Y2K frame. Though I purchased with the fan, I took the fan off because I don't know the wiring on the custom chopper that I have. The installation went well for someone without a mechanical background. About the most I've done with motorcycles is oil and filter changes. The instructions are very thorough and provide enough information with warnings about following them exactly. By reading and re-reading the instructions and taking my time, it was about a 3 1/2 hour job for me. Please see attached photos for complete installation on custom chopper. I also installed the PC Racing PCS4C Stainless Steel Polished Aluminum Flo Oil Filter from Amazon at the same time of installation of this and got more than 40 degrees cooler. The engine I have is the TP Pro Series 124 which is a very big V-Twin (124 cubic inch) engine that is air cooled. The engine runs at good temperature now.I will have the fan installed later in the Spring by a mechanic. It doesn't appear to be too bad, just finding the right wire and getting it connected correctly without screwing anything up is my main concern there.

I purchased this Jagg Oil Cooler because of an article I read in American Iron. I installed it myself on my 2012 Fat Boy Lo. This is a quality kit that you can install with basic hand tools. I did experience an issue where the fan didn't come on when the engine oil reached the prescribed temp, so I contacted Customer Service. They really took the time to troubleshoot the issue and when it wasn't resolved, they sent replacement parts.This is an expensive kit, but I believe that its well worth the money.

TEMP SW doesn't work. Quality control is bad.

Excellent product, reasonable installation. Lost one star because the electrical connection is not compatible with the the HD connection. This uses a standard blade connector with a piggyback where my sportster has a waterproof pin-style connector that this will not work with. Currently have the fan removed and plan on wiring it in more professionally over the winter. The fan is only helpful when stuck in traffic on very hot days and you should consider getting the cheaper model without fan assist if that isn't a big issue for you. FYI: this will do very little to change the cylinder head temp reported by the HD-LAN system, but will keep the oil and lower engine cool.

Great product. We'll something happened with the shipping. I contacted seller and they straightened it out immediately. Very pleased with them. Yes I would and plan on buying from them again for my other Harley. Thx

Everything was in box, instructions are to the point with pictures and detail. I had to buy a 7/16 inch allen socket which they said I had to have to take off stock oil cooler, so I have that coming from Amazon. I cant wait to get this oil cooler on my bike, it looks great, and I am well pleased with this product.

Product exactly as expected, which is rare.Shipped super fast.Dissapointing directions.Thermal set up works great.Fan works great.No leaks.

Wiring the fan to the brake light switch as instructed will not work on bikes with the CAN bus system. Doing so will cause the rear brake light to stay on, and the fan will never switch on. The brake light sees the fan as ground. The hot wire for the fan must be run straight to acc power. I wanted to try a solution that didn't involve stripping the bike to tap into a better source of acc power but didn't as I wanted to finish the install quickly so I could ride instead of shopping for more parts and waiting on delivery. Of course, there is a tech at Jagg that is rumored to be very helpful with this type of wiring problem. So, if your bike has CAN, you might consider calling JAGG. I have heard that they plan on updating the install manual at some point.Hoses: The worm gear clamps are too weak. The supplied rubber hoses are 3/8” fuel vapor line and should only be used as a template. The hoses in the kit have been reported to swell and leak. I upgraded to the braided hoses which were near impossible to install onto the hose barbs (even with lube). I also purchased their hose finishers which look great but still have the frail worm gear clamps.I recommend finding some trans cooler hoses or fuel injection hoses, whichever you are comfortable with. My oil pump pressures up to 50 psi going down the highway with the stock pump and Axtell kit installed. (So make sure the hose you use are rated properly).Purchase stronger clamps than worm gear clamps.Check the fan plug referencing the positive wire in the acc wired you just installed. My plug had red going black. Once I reversed wires in the fan plug, and tested, the fan turned properly (air flow to the rear).Take great pains to tighten the back half of the plate adapter sufficiently, but also tighten the 5 socket head cap screws on the front evenly and in a crossing pattern as with lug nuts on a wheel. The front half will leak if not tightened enough or properly. It would not hurt to bring the bike up to temperature after install, shutdown, let it cool, and recheck the tightness on the 5 socket head caps screw (your call).There were no torque values that I noticed in the install sheet (but may have overlooked). I found online info that said 15 lb-ft. I would tend to agree with that. Less than 15 and my adapter leaked around the flat gasket (not the o-ring).Oh yes, get it tight the first time, one bolt is near impossible to access once the hoses are in place.I don't have an oil temp gauge, so I cannot debate what people report about before & after temperatures. Some say 10 degrees, some 20 degrees, some none.
