I live in Arizona and none of us run oil coolers. I bought the Harley oil cooler with thermostat, always leaked around the adapter. I took it off and have never used it since. We ride all year even above 110 deg. HD does testing on new bikes out here in the middle of the summer. If they needed them they would come from the factory with them. Just ride and don’t worry about it. There are a lot of high mileage Harley’s out here in AZ without coolers and no problems.

Unfortunately victory is gone but Harley is still here. Makes you wonder who's smarter

Here in SE Louisiana its 90 F at 7 am part of the year. Get caught in traffic and you quickly know your 20k motorcycle is going to start overheating . On my 2013 Ultra I had the "Reefer" by UltraCool, it kicked on a lot in the city and traffic, and after I would pull off a long hard interstate run on to an off ramp on the interstate. The 20217 FLHXS had the HD fan assist on the factory oil cooler that did the trick. once i added the S&S cam and High flow oil pump it helped keep it a lot cooler. Now I'm on a 2021 Triglide and looking at DK cooler/filter relocation or UltraCool cooler , but you have to cut part of your lower out to mount it . I know it solves the heat problem no matter what performance mods I do later. My thought is cool engine ='s longevity and better performance.

I watched this oily in the morning. It was way cool.

1979, I bought a brand new Superglide with the new 80-CI engine. No oil cooler, after about an hour of riding, the rear cylinder would get so hot it would start to predetonate. The rear pipe would start popping flames with a loud POW POW POW. I would have to pull over on the side of whatever road, shut the engine off and let the air cooled engine cool. I sold that bike a few years later, I was sick and tired of dealing with it. Yes I told the buyer why I was selling it for only $3000 dollars in excellent condition. I quit riding Harleys for 28 years. I now own two more, BOTH have thermostat fan assisted Ultra Cool oil coolers and the Electraglide also has Love Jugs. Even tho a V-twin engine configured fore and aft is a dreadful design flaw, I'm riding Harleys again. If I ever have a single problem trying to keep a V-twin (incorrectly configured) air cooled engine cool again, I'm selling both damn Harleys and I will buy a brand new, the best motorcycle in the World, a Honda Goldwing. (get a thermostat fan assisted oil cooler.) Have a nice day.

Okay, when I have my pre-owned 2001 Sportster 883 tow-trucked in to the “vintage Harley-Davidson repair shop” for its imminent internal cylinder head rebuild, I will have them install an oil cooler. A short story about the Harley-Davidson Customer Care Department: they do not care about their own customer’s motorcycles once they see it as vintage. 😀

07 FLHT. Dealer fitted the Harley CVO oil cooler (my request) which was located low on the front tubes as per all CVO's. Lasted maybe 2-3,000 mile before it was holed and credited under warranty. Guess I was one of the unlucky ones.

Doc : thanks for having such clear , concise , and informative videos for us ! I’ve owned quite a few H-D’s since the 70’s , and remember back in the day , the bikers added oil coolers like the Jagg , which as you know mounted to either side of the frame’s down tube . This allowed “ clean “ air to run past it and STILL allowed said clean air to hit the V- twins forward cylinder . I traded my 83’ beloved FXWG Wide Glide in for a brand new FXLR Low Rider , and was SO DISAPPOINTED that Willie G and da boys installed the oil cooler smack dab in front of the engine’s front jug ! Now in the Texas heat , the air is preheating the air to the forward cylinder , and sending a blast furnace of scalding air to the rear cylinder … YOUR opinion please , sir ?

My opinion is strong. Every one is under the misunderstanding that this large "oil cooler" in front of the front cylinder is for the motor. It is not! It is only to cool the front and rear exhaust valves. With the size of the M8 motor the Motor it self need a 10 row with fan oil cooler besides the center oil cooler. Like the old days. Yes I would rather have two oil coolers on each side of the frame tubes and let the front cylinder receive fresh air. I am stepping down from my box now....Doc

My 2017 Freewheeler did not come with fan. Heating at rear of back cylinder head can be diminished by removing that cat that adds major back pressure in a short distance to back cylinder. Also using the EITMS ? to kick out fuel heating in back cylinder in summer traffic is a must imo.

One of the thing you didn't mention is that oil temperature at crank bearing and rod bearing while driving it is lot hotter, if you take stock bike and you put cam and pistons and ride like sport bike, yes you should use oil cooler.

Awesome insights Doc !

( instead of placing the new HD cooler directly in front of the engine ) This was a poor choice on the Motor Company’s part ; it would have been NO MORE expensive to have chosen this better location. , IMHO .

THANKS clear and clean explanation!!

I am going to install the fan assisted oil cooler on my 2017 ultra classic run hot and wanted to not worry on street lights

I'm going to have to slightly disagree with the reason for HD putting the fan cooler on the Trike models; rather than because they are moving slower, more stop and go or that they are in traffic more often, I believe its because of the higher 114 displacement, more engine load due to extra weight and rear running gear, and that they typically have or get Lower fairings which tend to block some free flowing air.. I live in the ozarks area, have a 107 Street Glide, and added Lower Fairings and I'm considering adding a fan to the OEM cooler and maybe I will be able to keep the Rear cylinder auto Shut-off feature disable..

I almost thought you were going to down them like a lot of techs do. I am all for function over looks (unless it is as ugly as a Suzuki Maduro or B-King). I am thinking about getting one for the crazy hot summer rides.

I never got the oil air cool concept but they cleared up a lot for me

Hello Doc, thanks for your videos!! I own a road king 103 from 2011- original-except air intake I believe. EIMTS is often on. I would like to make sure that the engine is cooled enough and improve the comfort. With the catalysator there is also lot of heat from the exhaust: what is the best for my me: cool flow fan, or adding the Harley fan cooled radiator. I believe that each of them can be mounted, possibly not with all the functionalities.

1: Harleys had oil coolers for at least 50 years. Its not standard for all models, but they are not behind. Because they are not always needed on all engines or models, I agree with their route of having the people who do need it pay and let the majority not pay for a part they dont need. 2: Getting the proper grade oil that wont burn off in the temperature you're riding at is far more important, including doing an oil change if that environment is going to change when you do a long haul ride. 3: Shut up and ride while you still can.

Hi Doc, I really appreciate your technical advice and you are a godsend to the Harley Davidson Community. I am the second owner of a 2003 Harley-Davidson Road King Classic. The original owner had the Screaming Eagle kit added after buying the bike new and the work was done at a Harley dealership and so the Pistons, Head, and Cam were upgraded and the V-Twin 88 became a 95. Question: I neither baby, nor do I hot rod my bike when riding, so would you recommend an oil cooler for my riding style? The bike has just over 20k on odometer and is a strong runner which was previously well maintained and cared for. PS. If you can also tell me what the Screaming Eagle conversion did for my low end torque, as well as mid to upper range torque?

I am still considering the oil cooler but today my Harley mechanic suggested the tuner over the oil cooler. The thought was any V-Twin larger than a 95, is going to generate considerably more heat and as such an oil cooler is a prerequisite. The evolution of the Harley V-Twin to larger and more power just doesn't cut it with old school Air Cooled. Thanks again Sir.

I was running 250 to 260 before I installed the oil cooler with 20-50 oil. I also have the Screamin Eagle oil pump assembly to try and flow more oil.

@@georgedishman3276 I ride a 2014 Fatboy Lo with an S&S 124 with 585 cams. My oil measures 250 - 270 degrees also (measured on my analog dipstick). I’d like to shave 40 - 50 degrees but I’ve heard most guys are only seeing a 20 degree drop in temp. I live in Canada…. so no Arizona heat here.

Hey Doc Harley I’m looking for a stock Engine Oil Cooler for my HD ELECTRA GLIDE SCREAMING EAGLE and it’s a 2005 and I can’t find one no where so can you help me please because I put and ULTRA COOL OIL COOL ON MY BIKE AND IT’S got the 103 on it and every since I got it installed it has had a oil leak and I’ve had it back to the shop and it still leaking so I wanna go back with the stock oil cooler but HD said they don’t manufacture it no more

Your story is all true. I am surprised about the Ulta cool. Their first edition did leak but the newest design is so much better. Your dealer could do a nation wide search to ask if an original dealer has a HD original oil cooler. My opinion I use Jagg oil coolers with the HD hose clamps….Doc

I thought that flowing problem was called prostate

Do I need to drain all the oil in a HD 103 to install an oil cooler? The oil has not run 200 miles. It's new.

No need to drain. In fact after installing you’ll need to add oil👍….Doc

@LowCountryHarleyDavidson Thanks, I watch your videos, some two or three times, they are very enlightening. I just bought a 2012 switchback with low milage but a bit neglected. I've been doing maintenance upkeep myself. One exception so far, abs brakes will be attended to by the Harley dealer.

Wouldn't it make more sense to use a thicker viscosity, like SAE 50 or 60? I live in Central FL and thinking about 60 in hot months, 50 cool months. The 20w-50 does not seem to cut it. No need for oil cooler, since you are trying to keep the viscosity.

Your observation is correct. Plus HD still suggests changing viscosity oil for temperatures. My personal thoughts are this was the practice in the past when passageways in the motor were the size of an Arby's plastic straw. Our motors have very small passageways in the cam cover, lifters and rockers that a 60 wt oil would have a hard time flowing. Also when 60 wt is cold (not up to operating temp) this creates high pressure. Sometimes enough to pop the pressure valve in the cam cover. 20w-50 is a good oil year round and with an oil cooler with thermostat temperatures can be kept in the designed operating temperature for oil and motor. Thanks ~ Doc

Do you recommend a oil cooler for 2019 Harley iron 883 ?

Doc, …… i have question: Years ago I had a Sportster (1994) and there used to be an aftermarket round oil cooler that after you removed the oil filter you could screw on the finned oil cooler on and then the new oil filter behind it. It also gave your Sportster slightly more oil capacity along with extra cooling during very hot climates. During the winter time there was a leather sleeve that slid over the cooler to block the now much colder air flow on the fins but still allowed for a tad larger oil capacity w/o having to remove the cooler. I wanna say HD used to sell this product but have not seen one in 26 years. Any ideas on who made these animals and where/how I can get one now for my bike ?
