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.
While your at it take the transmission cooler off your cars transmission. How do you know how hot the oil temp gets on your harley. An oil temp gauge is also a good idea.
What bike do you have and what oil temps do you see? I live in Canada and ride a 2014 Fatboy Lo. Oil temps on the dipstick show 250 - 270 degrees at temp. I’ve got an S&S 124 with 585 cams… Seems hot cuz the old 103 usually ran around 220 degrees.
Doc i've watched a lot of your videos and YOU BY FAR as the most knowledgable som bitch i've ever seen on HD bikes. Thorough, great radio voice, and informative. Keep up the great work and ride on!
Great addition, I put a Harleydavidson fan assisted oil cooler on my 2018 RGS after it got installed with a hotted up SE stage 4 , I like it and it does help I've put 32000ks on bike since install.allso I put a fender skirt on my front gaurd and mounted it 1/2" lower to protect my fan assisted oil cooler , I get no mud,dirt, stones on cooler ,still looks brand new , I do across the board , riding.
I bought a Harley Davidson oil cooler for my 1983 FXWG in 87 before Squadron moved to Japan. Left it on when I got transferred to the Philippines. Still have it installed!
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.
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.
I put a Harley on my 08 sglide and 09sbob hoses bent to fit. And was hoping they had thermostats. Thanks for informing me. Not much room for a fan though 🍻
Glad to hear Harley Motorcycles are updating their engineering. USA built Victory adapted this 20 years ago. Welcome Harley. Keep the improvements coming.
@trigun890. You need to look into why Polaris halted production of Victory, The reason had nothing to do with Harley & everything to do with Indian. Typical response!
Liked Sunday late afternoon 18 April 2021! 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.
I have a 05 FXSTDI, live in Southern CA Hermosa Beach, in the summer I can't get high enough on my toes to get away from my oil tank. Going to put an ultra Cool w/a fan on my bike. I'll take 20⁰ temp reduction, smaller blister😬 my bike now has 10k miles on it, so I do ride a bit.
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.
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.
According to my catalog neither will fit your bike. A HD oil cooler will help the motor. I prefer the Jagg 10 row with fan or the ultra cool with fans. To help you feel cooler....stick your knees out in the wind :) Thanks ~ Doc
I have ridden a HD for years and the one thing that always comes to mind is how so far behind the curve HD are when it comes to adding positive innovations. This is a prime example. Always playing catch up.
Just because its not standard on all models doesnt mean its new. Harley had stock oil coolers on their bikes since the 70's. Its just a different package, like how some cars could get the power window upgrade back in the day.
@@ryanmoore2779 I am a motorcyclist!!! Everything cycle related interest me , itchy boots videos are great ,about her travels. Moto GP videos are great because of the balls those racers have!!! But lots harley videos are about fixing problems with their bikes !!! I just find it interesting that they seem to think that straightin out that crap is normal !! Watch the " our ride life " new video, 95.000 miles on the chrome air compressor and it needed cams,oil pump and other stuff and they were smiling going to pick up the bike . I would be PISSED paying $$$$$$$$ for all those repairs!!!🤮🤮🤮🤮🤮🏍🏍🏍🍺🍺🍺
If you have it installed at a Harley dealership they can do it correctly and then no worries. I do know from watching Doc, the computer on the bike looks at everything and if it sees something it doesn't like, it causes problems.
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'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..
Hello @Low Country Harley-Davidson My name is Yan and I have a v rod muscle 2014 and I am doing the coolant replacement. In the service manual says 2.4L, is already open the Radiator drain plug and Front Cylinder Coolant Drain Plug in just removed 2L coolant. Is that correct? How do I find the Rear Cylinder Coolant Drain Plug? I can not find it ... could you help me?
Doc, Will an oil cooler help for my bike? I have a stage 4 setup and it runs hotter than normal with the cams, and heads . But in traffic I dont think this would help? at lights and such.
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
@@LowCountryHarleyDavidson Thanks for that most detailed response ! I was “ happy “ to see them install this oil cooler ; I was just shaking my head and asking myself - “ WHAT were their engineers THINKING ? “
I have a 2018 Road Glide Special and I’m running @300-316 and in stop and go detour at one time and got up to 369. I have the stock air cooler. Will a fan behind it work to lower it? I track my temp via My Power Vision engine temp. What’s a good replacement aftermarket that’s a direct replacement with fan. Or add a second oil cooler to side with fan assist. What’s your thoughts?
I have a question I hope you have an answer to..My GF has an 06 1200 Sportster which has the pop up oil cap and the problem is her leg keeps popping up the cap while riding and oil seeps out all over everything and I can not inure out how to prevent this from happening. Do you know of any way to stop this..?
Awesome insights Doc ! I’m ( still ) highly disappointed that HD didn’t follow Jagg’s engineering by having the location of said oil cooler to either side of the down tubes of the front of the frame to allow “ clean air “ for the oil cooler AND clean air to hit the front of the front cylinder ! ( 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 . Peace ☮️
Mike, i have a 2012 FLHRC that looks like it has a factory oil cooler but my TC103 even with synthetic seems to run hot and limp mode comes on too soon in my opinion......help any ideas?
Hey doc I have a xvs vstar 250 with cold air intake custom pipes drag style and a 115 main jet I took off the air injection system I use mobile 1 racing 4t oil would you recommend an oil cooler for my bike
Thank you for this video Doc. I looked into putting on one of these coolers until I heard from a forum member a while ago...that in cold/cooler temps, the cooler can cause the oil to "froth" up and that would NOT be a good thing. I didn't hear you address this. ???
@@LowCountryHarleyDavidson I understand that you can also add a bypass valve that you can shut off the flow to the cooler for those of you who live in colder climates.
Doc, I was listening to Kevin Baxter video on camplate n he talked about oil coolers. He disagrees with Harleys system because it flows dirty oil thru the cooler first n then thru the filter. He uses Jagg coolers.
Does the oil that cycles through the oil cooler the primary oil. ? Sorry I honestly don’t know. And I had something hit my oil cooler and it began to leak slowly.
Hey Doc I have a 2018 Harley Breakout anniversary with a 117 Screaming Eagle kit fitted can I upgrade the oil cooler on my bike does the one you show fit my bike and can I get it from you I'm in the UK
Hi im building a 2013 street glide air cooled harness etc.... ive bout everything for it from ebay.. so..when it came to getting the engine.. ive purchased an 2014 liquid cool ultra limited twin 103 engine.. now.. ive purchased the liquid cooling system..but how to hook it up to a 2013 oil cool harness and bike...
I ordered the fan for the oil cooler but once on the lift, they found out the chrome cover I had on it was not compatible and it was either a choice of having the fan and loosing the chrome cover or not installing the fan altogether. After paying $$$ for the chrome cover, I choose not to install the fan. I just have to make sure not to get stuck in stop & go traffic. Oh, the police version have them on from the factory. *** We, the techs and I, re-read the catalog description and it did say it wasn't compatible. DOH!!! Cool thing is they didn't charge me anything for the mishap and kept the fan and restocked it.
Hello Doc. Thanks for the info. I was curious if adding an oil cooler messes with the PSI rating of the oil system itself on the motorcycle? I was just curious if the stock oil pump can handle the extra oil lines, cooler, and all of the curves and ups and downs. Maybe I'm overthinking it. Anyways just curious and since you didn't mention it maybe it's not an issue. Also while I have you could I add a stock H-D oil cooler from say a 2017 Ultra or Freewheeler to my 2016 Ultra with liquid-cooled heads? Thanks Doc.
Two points, purchasing an oil cooler designed for your Harley-Davidson will work with your designed oil pump. So installing an M8 oil cooler on a twin cam is not a good idea….Doc
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.
I have a 16 Heritage with true duals and a big air breather. The pipes are wrapped. I recently added a fan assisted cooler with thermostat. I rode yesterday and it was a pretty cool day. The bike temp got up to 273 in stop and go traffic but was running around 250 otherwise. I’m worried about the summertime. Is there anything else I can do to cool it down?
You have checked all the right boxes. Keep the oil clean as much as possible. Make sure your “tune” is correct. Too lean will raise the temperature. And keep moving, this is an air cooled motor👍…Doc
Hey Doc, Would I need an oil cooler on my 2017 Street Bob? It’s got stage 2, aftermarket Reinhart exhaust , and the engine cam. Or is it good for the engine over a the lifetime of the engine or bike, high mileage, etc? Not planning on doing stage 3 or 4 but maybe in the future.
Sir, It gets hot out here in Texas. I have a 2017 CVO Street Gide. It’s set up to be water cooled. Would it be overkill to add a fan assisted oil cooler. What do you suggest the temperature should be for the 2 fans come on? What should the temperature be to turn them off or what should the differential temperature be? I was told 8 degrees I think it should be more.
Yes I would add an oil cooler with fans. Read the fine print when choosing. Many oil coolers with fans do not fit on twin cooled Harley-Davidson with the lowers and water pump. My Jagg with fan comes on at 210. Thanks ~ Doc
Harley-Davidson offers their tried and true premium oil cooler without fan. There are several aftermarket manufacturers who are offering an oil cooler with fan (s)..Jaggs and Ultra Cool are at the top of the list. Do your research, follow the reviews by people who have installed and rode with them in the heat. Thanks ~ Doc
If it does, you will see it on the front lowest part of your frame (in front of the engine) with the lines going into the motor right above the oil filter.
My 2019 softail slim came with an oil cooler but without an electric fan. Would it be possible to have an oil cooler with an electric fan installed by the dealership?
Doc do you need to re-tune the bike after installing an oil cooler? I ride mostly in city traffic and my 2005 twin cam gets my right thigh medium well while at a traffic light.
It would’ve really been nice if Harley would’ve included a light or something to tell you when you’re Harley Davidson fan assisted oil cooler fan is on or off
How about using steel braided lines n not worrying about stones flying . I had one on a 85 fxr. Can I get one for an 09 heritage softail? Would you know approximate cost of parts?
Steel braid covered oil hoses may well help guard against foreign object damage, however the heat exchanger body itself remains at risk of puncture damage from foreign objects unless protected by a wire mesh screen. Thanks, Ralph K in St Louis, MO
You, like the rest of us, have to make a living. I understand that you cannot answer questions online. I wonder if I might be able to get a paid phone consultation with you? My questions are general, nothing that would cause a conflict with HD. I'd like your ideas on shift change and cruising rpm, for instance. I have a 2013 Super Glide (out of warranty.) Thanks for your videos.
Ive been wanting one for my 08 xl1200 nightster its had a few mods and I think this is making it run a little bit hotter then normal. I'd love to try one to see if it makes a difference but I'm not sure if it Will fit on my sportster with the forward controls does anyone know if it will fit??

Thank you for this video Doc. I looked into putting on one of these coolers until I heard from a forum member a while ago...that in cold/cooler temps, the cooler can cause the oil to "froth" up and that would NOT be a good thing. I didn't hear you address this. ???
The Harley-Davidson oil cooler mentioned has a built in thermostat that is used to prevent a "froth" up from occurring due to cold temperatures.
@@LowCountryHarleyDavidson I understand that you can also add a bypass valve that you can shut off the flow to the cooler for those of you who live in colder climates.
Very good thank you
Thank you too...Doc
Have you ever tested whether it's really worth it to purchase a Dooxi Car Adaptation products?
Doc, I was listening to Kevin Baxter video on camplate n he talked about oil coolers. He disagrees with Harleys system because it flows dirty oil thru the cooler first n then thru the filter. He uses Jagg coolers.
HD of Gastonia did my oil cooler. It was hard to make it not leak, but they finally got it right. 2000 Heritage
Its a Harley...... I thought it WAS supposed to leak ??? Y did they fix it ?? Haha
Doc What's your opinion on Love Jugs oil cooler ?
Do you recommend a oil cooler for 2019 Harley iron 883 ?
Does the oil that cycles through the oil cooler the primary oil. ? Sorry I honestly don’t know. And I had something hit my oil cooler and it began to leak slowly.
Hey Doc I have a 2018 Harley Breakout anniversary with a 117 Screaming Eagle kit fitted can I upgrade the oil cooler on my bike does the one you show fit my bike and can I get it from you I'm in the UK
Hi im building a 2013 street glide air cooled harness etc.... ive bout everything for it from ebay.. so..when it came to getting the engine.. ive purchased an 2014 liquid cool ultra limited twin 103 engine.. now.. ive purchased the liquid cooling system..but how to hook it up to a 2013 oil cool harness and bike...
Wise words 👏
Thank you...Doc
@@LowCountryHarleyDavidson/ I pay attention when u speak up
Is it possible to ad a oil cooler on a Yamaha V Star 750? Your comment! Thank you.
I ordered the fan for the oil cooler but once on the lift, they found out the chrome cover I had on it was not compatible and it was either a choice of having the fan and loosing the chrome cover or not installing the fan altogether. After paying $$$ for the chrome cover, I choose not to install the fan. I just have to make sure not to get stuck in stop & go traffic. Oh, the police version have them on from the factory. *** We, the techs and I, re-read the catalog description and it did say it wasn't compatible. DOH!!! Cool thing is they didn't charge me anything for the mishap and kept the fan and restocked it.
Chrome won't get you home, an oil cooler will!
harley's V-twins need all the help they can get, cooling. and oil-coolers work.
Oil cooler was 1 of the reasons I went with Victory Cross Country instead of a Harley in 2016.

Do the 117ci engines have an oil cooler?
Hello Doc. Thanks for the info. I was curious if adding an oil cooler messes with the PSI rating of the oil system itself on the motorcycle?
I was just curious if the stock oil pump can handle the extra oil lines, cooler, and all of the curves and ups and downs. Maybe I'm overthinking it. Anyways just curious and since you didn't mention it maybe it's not an issue.
Also while I have you could I add a stock H-D oil cooler from say a 2017 Ultra or Freewheeler to my 2016 Ultra with liquid-cooled heads?
Thanks Doc.
Two points, purchasing an oil cooler designed for your Harley-Davidson will work with your designed oil pump.
So installing an M8 oil cooler on a twin cam is not a good idea….Doc
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.
Oil cooling is very good.
Nice video, with HD being air/oil cooled, and temp is pretty crucial, why don't they put a temp gauge on the bike ?
Living in South (HOT) FL. Thinking seriously about getting an Iron.. but concerned about the heat. Can an oil cooler be installed on the new Irons??
Yes, they are side mounted, I believe
Doc
Saw a vid that recommends add a small amount of mmo to the gas tank with each fill up.
What are your thoughts on this

Is it hard to install on a 2016 Limited
I have a 16 Heritage with true duals and a big air breather. The pipes are wrapped. I recently added a fan assisted cooler with thermostat. I rode yesterday and it was a pretty cool day. The bike temp got up to 273 in stop and go traffic but was running around 250 otherwise. I’m worried about the summertime. Is there anything else I can do to cool it down?
You have checked all the right boxes. Keep the oil clean as much as possible. Make sure your “tune” is correct. Too lean will raise the temperature. And keep moving, this is an air cooled motor👍…Doc
Just a suggestion stay away from chrome oil filters, they donot dissipate heat like the black one's
Hey Doc, Would I need an oil cooler on my 2017 Street Bob? It’s got stage 2, aftermarket Reinhart exhaust , and the engine cam. Or is it good for the engine over a the lifetime of the engine or bike, high mileage, etc? Not planning on doing stage 3 or 4 but maybe in the future.
Glfmar Madison your bike should do well as is, just make sure it has a good tune.
Sir,
It gets hot out here in Texas. I have a 2017 CVO Street Gide. It’s set up to be water cooled. Would it be overkill to add a fan assisted oil cooler. What do you suggest the temperature should be for the 2 fans come on? What should the temperature be to turn them off or what should the differential temperature be? I was told 8 degrees I think it should be more.
Yes I would add an oil cooler with fans. Read the fine print when choosing. Many oil coolers with fans do not fit on twin cooled Harley-Davidson with the lowers and water pump. My Jagg with fan comes on at 210. Thanks ~ Doc
Doc. I have a 2012 Roadking police, I was wounding if Harley makes a fan assist cooler for my bike or do you know of a good aftermarket one
Harley-Davidson offers their tried and true premium oil cooler without fan. There are several aftermarket manufacturers who are offering an oil cooler with fan (s)..Jaggs and Ultra Cool are at the top of the list. Do your research, follow the reviews by people who have installed and rode with them in the heat. Thanks ~ Doc
Great vid Doc. I own a 2018 lowrider,does it have an oil cooler.
If it does, you will see it on the front lowest part of your frame (in front of the engine) with the lines going into the motor right above the oil filter.
@@CovertOperation13 thanx man
My 2019 softail slim came with an oil cooler but without an electric fan. Would it be possible to have an oil cooler with an electric fan installed by the dealership?
HD does not offer a fan assisted oil cooler for the Slim. I went with Jagg 10 row with fan..I love it! Doc
Doc do you need to re-tune the bike after installing an oil cooler? I ride mostly in city traffic and my 2005 twin cam gets my right thigh medium well while at a traffic light.
No re tune with an oil Cooler addition. But maybe look into your tune.
Timing might be too advanced at idle....Doc
It would’ve really been nice if Harley would’ve included a light or something to tell you when you’re Harley Davidson fan assisted oil cooler fan is on or off
Nice idea...Doc
@@LowCountryHarleyDavidson Curious if those upgraded gauges for the road king on Harley’s website would have anything like that built into them?
Whats your thought on the HD 260082-05c cooler for a 2000 RK ? Thanks .
Yes go for it. I am a big supporter of a oil cooler on any Harley-Davidson. Thanks ~ Doc
If I were HD I would have made the oil pan with proper fins on it. Little grooves on my '99 TC88 Dyna.
How about using steel braided lines n not worrying about stones flying . I had one on a 85 fxr. Can I get one for an 09 heritage softail? Would you know approximate cost of parts?
Steel braid covered oil hoses may well help guard against foreign object damage, however the heat exchanger body itself remains at risk of puncture damage from foreign objects unless protected by a wire mesh screen. Thanks, Ralph K in St Louis, MO
Ha Doc, how about the twin cooled model of the 17 CVO with Stage iv? How's that cooling compare?
Twin cooled is awesome in controlling heat. I don't believe anyone is offering a larger oil cooler or fan assist at this time. ~ Doc
You, like the rest of us, have to make a living. I understand that you cannot answer questions online. I wonder if I might be able to get a paid phone consultation with you? My questions are general, nothing that would cause a conflict with HD. I'd like your ideas on shift change and cruising rpm, for instance. I have a 2013 Super Glide (out of warranty.) Thanks for your videos.
Ive been wanting one for my 08 xl1200 nightster its had a few mods and I think this is making it run a little bit hotter then normal.
I'd love to try one to see if it makes a difference but I'm not sure if it Will fit on my sportster with the forward controls does anyone know if it will fit??
HD catalog suggests part # 62700082. Thanks ~ Doc
