Wet Head Harley-Davidson, Twin Cooling Expanding or Buying Time
Brought on by customer feedback from project Rushmore Twin Cooling was a big risk for Harley-Davidson. Harley-Davidson responded to customers requests for reduced engine heat by using liquid cooling for the hottest part of the cylinder heads, the exhaust valves. This greatly reduced the amount of radiant heat felt by the rider, but there are a few things you'll want to know about the Twin Cooled system. A major misconception is that the motor is now liquid cooled, well sort of. While the heads are liquid cooled partly, the cylinders and engine cases still rely on air flow and oil for cooling. While intended as a comfort feature it did allow for some performance upgrades on the side.

I think the M8 will be the last of the air cooled built in mass. The pan American revolution engine will likely start crossing platforms. The sportster died in Europe due to their emissions. Great place for the revolution to debut

I just finished all upgrades to my 14 SGS 103 to 110. It’s done! All air cooled with love jugs. Runs just as I hoped it would. I pull a trailer and wanted low end power. It pulls like a train😊. Anyhow, if I were in market, I would prefer a total water cooled scooter like the challenger. I hope H-D will offer a full dressed challenger… challenger. I would seriously consider it. Hell, I would buy a challenger if it had lower fairings with speakers along with the tour pack.

Great video, I had just learned about the twin cooling. Wonder why it has not crept down into all the touring models? They really did a good job hiding the coolers. If I were looking at a Street or Road glide special I would consider. But its a big $$ jump up from the base model.

It doesn’t work, my 2014 cooling system failed twice and most people I know with this same setup have had water pump failures, right up to present day. It’s a similar situation to hydraulic clutches, Harley just can’t get them to work. They finally gave up on the hydraulic clutches and should give up on the liquid cooling.
A couple of years ago we were on a 2 week crosscountry trip. One RG, my Ultra Ltd and a 2014 CVO Ltd twin cooled. All three bikes had Trask turbos installed. All of us were pulling 300 lb camper trailers. The second day in on a Sunday, the CVO water pump failed. We were an hour or so to a dealer so we headed there, keeping an eye on temps but of course they were closed. We were sitting in the parking lot trying to decide what to do when a bike pulled in and asked if we were ok. Told him our situation and he said "just ride it, wont be a problem". We were a little skeptical until he told us he was the head mechanic at another HD shop. We didnt have much choice so we carried on, again watching out for temps and knocking. Following day we tried to find new water pump but they were out of stock because a lot of people were having failures. Long story short, we continued our 2 week trip and put about 5000 miles on the CVO without the water pump working with no issues at all. Got home and replaced the old pump with the new upgraded pump. Bike is still running like a champ.
Bought a 2014 Ultra Limited brand new. 40,000+ miles on it now, no coolant or water pump problems so far. Traded in a Gold Wing for it. I do have to admit, the Gold Wing was almost as reliable as the Harley. But not quite.
On my 2012 ultra limited, I run a dual fan oil cooler, remote filter, and jug fans. I live in Texas and ride a lot in the southwest. Runs nice and cool. I completely rebuilt the bike in 2022 instead of buying a new one. Did not want tc heads. I'm glad I did that. Now I have exactly what I want for a lot less money. Ride safe, everyone!!!
I live in Perth West Australia 🇦🇺 and rode my 03 fatboy on 42 degree Celsius for 600km no power loss and no issue of what so ever, no need for extra headaches of radiator, thermostat,water pump, coolant and extra $$$ in maintenance Ride safe everyone

Yep. Rode north from Blue Mountains for 2000km middle of summer on my stock Sporty. No issues. I have nothing against water cooling. But everything I own is air cooled. Even my car, which my brother drove from Sydney to Perth and back in 45°C days through summer.
2014 Ultra Limited - H2O Pump went out @ 30k (P1019). Was 100+ miles away, called mech said it was fine to ride home, just keep it under 3k RPM's. $500 later = fixed ($300 upgraded part / $200 labor). There was a recall for later Rushmore models and if you find that your H2O pump fails (and it will) do not replace it with OEM, get the upgraded 2017/2018 part. As to selling these twin cooled bikes to the "look at me ppl", have owned & ridden many HD air/oil-cooled bikes over the years & at my age now can afford + appreciate my rolling couch - I still ride in the rain / heat / etc... but now do it in style and comfort!
I own a 15 CVO RG Ultra that is twin cooled. I live in western Arizona where Temps can be very extreme. I love the liquid cooling simply because of being in situations (city traffic and lights) when my cooling fans engage and I know my motor is in need cooling and traffic doesn't permit it. Its a nice advantage and I'm at 75,000 miles and I've never had an issue with the cooling system 👍👍👍

That's quite a few miles! That bike doesn't sit much at all, glad to hear it's working well for you out there!
Just got home from a 4300+ mile trip to the Gaspe Peninsula. As we we leaving from New Brunswick, the check engine light and temp light came on after about 7 miles on a cool morning. Since the town we stayed in had decent resources, we turned around and waited for the Canadian Tire to open, and while we waited, had a quick look at the coolant overflow tank, which showed low level. So we bought a jug of coolant, topped off the tank, and headed back to the moose-infested riding day, which was beautiful--no issues. Next morning, took off again, and just before our first gas stop at about 180 miles, the temp and CEL came on again. Had a look at the coolant tank again, which was full to the top this time. So, we drained out enough to get it back to the full line, and then took off again, without issue. Next morning, both lights came on again after about 3 miles, and from then on for the next 1000+ miles home, both lights were on within a few miles of every startup, and never again went off. Along the way, I forced the fans to kick on a few times, just to see if any heat would come out of the lower fairing vents--ambient air only, every time, so yeah, the pump was shot. Never leaked a drop, and never ran poorly, and after reading several real-world accounts like this before making our way home, we soldiered on. 90+ degree heat, Chicago traffic, road construction, rain, and heavily loaded 2-up, the bike just didn't seem to care. Mind you, I made sure to coast with the clutch in when slowing down a lot, tried my best to not let it idle very long, activated the EITMS, ran the best fuel I could get, avoided full throttle, kept the speeds in check (70 and below, except when passing big trucks). I'm going to pick up the new pump upgrade kit this morning in about an hour, and wanted to share this story to hopefully help others who might overreact when this happens to them. 2014 FLHTK, 62000+ miles as of last evening. YMMV
Yes I own one and confirm it is much cooler to ride on hot days. I also own a 103HO that has limitations in heavy traffic so bring on the twin cooled engines in my opinion.

You can run as far as you need to at normal speeds ... for example ...one of my bike was a 96ci took it out to 107 port polished everything and everything thing else ... standard oil pump ... no oil cooler...it did require compression releases ...did parade duty no problem ... can't see where it would be a problem except for warranty if they knew ...yall have a good one ... thanks for the content...

I bought a 2014 ultra limited new and love the twin cooling. Zero issues so far.
When my 15 Limited water pump failed at 8k I still road it in the heat for almost a month before I brought it in for the new #p/n pump and so far so good currently at 40k no problems.
I bought a used 206 Ultra Limited last year. The salesman didn't really give me much help as to what all the features were. I soon found out that I knew more than he did. I checked my coolant reservoir a couple of times and found it to be a bit low when I thought it was running a bit different. A couple of months ago, right before Thanksgiving, I noticed a puddle of coolant under the bike after I had parked it for a short time. I have the extended warranty and took it to my dealer. They checked it and said it had been overfilled. They didn't charge me but I know I didn't overfill it. So what I'm trying to say is that I'm not quite sure about the "wet head yet. Love your videos, I'm learning a lot about my bike and the 103 in it.
I own a 2014 Ultra Limited and love the twin cooling system and as a plus I run Amsoil 100% synthetic base stock oil in all three holes which brings my engine temp down 12 more degrees and more compression. Now that's what I call COOL!!!!.

I love my Tri Glide. I also added Love Jugs formore cooling. The fans run after the bike shuts down after a long ride normally, but when I kick in the Love Jugs fans, the internal fans don't keep running after shutting down.
I had a 2007 Street Glide with the 96 twin cam and then purchased the 2015 Ultra Limited 103 twin cooled and now have a 2021 Ultra Limited 114 twin cooled. To be honest with you I didn't give much thought about it. I didn't feel that much difference between all three of my bikes. I just installed the Harley Davidson cool fan a couple of weeks ago will see if it helps with heat. Thank you for sharing the video.
From what I understand - and I’m no expert, as the newest bike I’ve owned is my current ‘74 shovelhead - is this: panheads run cool, shovels kinda hot, evos run cool, twin cams run hot as hell, and Milwaukees run fairly cool. So I can see the reasoning to try and cool down the twin cams, particularly the heavy touring bikes.

Ironically on the Twin Cooled bikes they didn't do it for emissions or performance, it was purely rider comfort. Although they could of put some compression in it for power with the cooler heads.

I think Harley Davidson should've used a liquid cooling on the cylinders also. They can put fins on the liquid cooled engine and make it look more like their air cooled engines. In fact some of the Japanese motorcycle manufacturers have done that. I think it was Honda in the 80s that said they left fins on her liquid cooled engines for two reasons. The first was the look. The second was it allowed them to run a smaller radiator. And I agree with you the big oil coolers on the newer softails could be replaced by a radiator.

I've been saying that same thing for years! Kawasaki, Yamaha, Suzuki and Honda have done that same thing for years! Kawasaki and Honda even went as far a single crank pin with over head cams they loped very very close to a Harley. Enough that Harley tried to patent the sound which was denied. Honda went back to dual crank pins which is more efficient but the dual crank pin sounds raspy to me. Kawasaki still uses the single crank pin but the new 52 degree 1700 vulcan motor just doesn't sound as close as it used to with the 1500 and 1600. The 900 sounds decent but it's not nearly the sound they used to get with the bigger inch Kawi's.

Right on! When you're on the bike for hours a time you really notice it there!
I just bought a new Tri Glide a month ago. I have no problem with the liquid cooling on my bike. Those engines need all they can get to keep cool. I have a two year warrentee on the Trike so I am not going to worry about it for now. Personally I think it is cool when you stop, turn off the engine and hear fans still running to cool down the liquid.
I haven't mounted my oil radiator yet on my 2000 heritage due to a defect in the construction in my opinion, too narrow channels in the transition between hose connection and adapter / radiator. The channels from oil pump to filter are nearly 8 mm but the connection is only 6 mm, a bit much considering that my bike has a high flow pump and a better camplate with greater flow installed, i have to change some parts first and also i had to leave the adaptor to a friend that can help me by welding on some more material so i can drill out holes and thread them for larger couplings before mounting. A side-mounted that i bought is also preferred instead of a central-mounted one that obstructs air flow, there are low-mounted solutions, but there you have the splash from the front wheel instead.
I have a 2015 Ultra Limited. I love the bike. There are times when I can feel the heat coming off of the radiators.
Yes sir! If I ever get a touring bike it will be a ultra limited and I would shoot for a 2016 with lower mileage. As always thx for the info!
I have a 2016 road glide ultra that has the liquid cooling system. I like it very well but I did have the water pump to go out. I replaced it and upgraded to the m8 water pump which is more durable and beefy. I’ve had no problems since.
I just came across this video 2 yrs after its debut. I own a 2015 Road Glide CVO now with a 117” Stage 4 upgrade since I hit 95K miles. My bike currently has 137K miles since new. I’m the original owner. I’m now on my 3rd liquid cooled pump as of last weekend. The original one lasted 76K miles. It was replaced under extended warranty with the new and “improved” version. Which lasted 61K miles until last weekend. After my dealership installed my 3rd liquid cooler the mechanic took it for a test ride and immediately returned back to his shop after hearing transmission noises. Turns out the bolts holding the transmission together loosen over time allowing all the transmission fluid to drain out from its seal. So my bike remains at the dealership waiting on parts, as I wait for another huge repair bill since I’m no longer under extended warranty. It’s times like this I hate being a beta-tester for HD, since it’s now on my dime.

Hello, I own a 15 Ultra and the cooling pump just went out at 21900 mi. I’m replacing it myself. The instructions are good except for where to move the wiring and plugs that the fans plug into. I have viewed the videos where there has been trouble getting the 2 black color screws out at the bottom of the lower fairings. I got mine out with no trouble, but went easy and slow using hand tools. Wouldn’t recommend using any kind of power drive tool. Harley used a lot of blue thread locker on them. Before reinstalling them I tapped out the inserts just enough to remove thread locker inside them. If you don’t, the screws are tight going back in. I’m going to use a small drop of blue thread locker about midway of the screws before installing them.

Buy it new for 18 grand and a few years later you may see 10K out of it. But anything air cooled still commands a huge premium used.
Hey Gixxer hope all is well, yah I run a 2016 Limited and have no complaints at all. I get the cooling adds extra parts and earlier models had issues but you can put an M8 pump and t stat on if you want to upgrade the system and it's not to expensive for piece of mind. But so far so good no complaints here. And on the internet you can find the manufacturer of the Harley coolant Ok here it is Peak Global Lifetime 50/50 (from another post and he got his info from the MSDS sheet) and save some cash there 20 at HD or 9 form Napa.

An oil cooler kit by DK customs (Jams) would add a real benefit to running cooler and an added benefit of routing oil through the oil filter before going through the cooler, unlike the stock oil cooler (on oil/air cooled engines) that runs the unfiltered oil through the cooler then through the filter. Something to think about for the standard M8.

Great point! I was surprised they would run oil unfiltered through the cooler on the M8, that's just asking for trouble. It's a shame they keep the oil cooler on the twin cooled bikes since the rest of the engine is still oil cooled.

I note the engine temp on my 2014 ultra limited is a touch higher than a none twin cooled equivalent, I have the latest Pierburg pump upgrade and feel the lack of an oil cooler is a factor in this.
Things done, mainly the higher compression, is what produces the higher output........they were allowed to do those things because of the head cooling hmmmmm radiators in the lower fairings......air goes thru radiators to cool the coolant thru heat transfer, the air pulls away the heat.........then this hot air is directed onto the riders legs? might be nice for winter riding BTW never knew of this
Two years ago I was in San Francisco and my water pump went out at sixty thousand miles. I rode it to Seattle and replaced it with the updated brushless pump like the N8 have no problems at eighty one thousand miles. 2014 limited.

Ive been enjoying my twin cooled 2014 ultra limited. I came from a switch back. Both had an intake and V&H propipe. But I was surprised the big ultra felt more peppy than my much lighter switchback.
I have a 2015 ultra road glide w/ 32000 miles the water pump went out had to ride 40 miles to get back home was 80 deg outside didn`t have any trouble on the way home replaced pump with upgrade m8 water pump. had to reroute some hoses and put on a new bracket but all went well! have not had any problem so far.
Another great episode. Thanks again for your hard work.

Harley-Davidson simply had to come up with changes to their air-cooled engines, if they would want to keep up with European Environmental legislation. It is well known that liquid cooled engines have an easier job in that case than air cooled engines have. So coming up with liquid cooled engines by Harley Davidson was not to satisfy their customers but is was inevitable since they had to do so due to legislation. That same aspect was the reason for Harley Davidson that they had to discontinue the entire air cooled Sportster line-up in Europe and to come up with at least one water (liquid) cooled motorcycle to replace the mid sized motorcycle line-up as a replacement for the Sportster mid sized line-up: the Pan American. The motor of the Pan-American of course is the replacement motor for the entire Sportster line-up. We all have seen the pictures of the future bikes to replace the Sportster. The question is not if Harley Davidson will have to change from (all their) air cooled to liquid cooled engines, the question is when will they be ready to do so. After all... Harley Davidson has been given a deadline to start producing environmental friendly motorcycles.

You made an excellent choice in cams! That bike has to lay down some power now!
I own several Harleys of early to late years, none liquid-cooled, I was looking to buy a revolution (water-cooled) but they stopped production. don't know why maybe you could tell us. my point, why discontinue a water-cooled bike, only to continue a partially cooled bike. any Harley set up right, (a good tuner, intake, & exhaust) will run a lot cooler and better, even my Panhead & shovel run cooler than any twin-cam or Evo I own. EPA has made things detrimental to HD's v-twins, so just bring back the water-cooled bikes. tks, keep em running!
I bought love jugs for my 117 twin cam. Cylinder Temps use to jump up to 306 degrees in traffic. Now they hover around 257 degrees in traffic during warm days around 80 degrees out. But I would like to see a full water cooled engine for all softail models in the near future.

Why not split the radiators? Just re-arrange the hoses. Harley does not offer oil coolers for these models, due to the cooling system taking all the forward area. Harley engineers should have considered this during the design stage. Im probably not the first to consider this practical upgrade. Ken

You did not answer my question about splitting the raditors. I presently have a 2015 Ultra Limited. Love the bike. It has 42,000 with no issues yet, except for the junk compensator, which I swapped for a sprocket. The rear wheel has rubber cushions and will take any shock load. Also went with the Hayden tensioner, execelent. A little rattle in the primary due to the clutch pack chattering in the basket. Liveable. I still think that by splitting the radiators would accomplish removing heat from the engine by cooling both the coolant and the oil. Doesn't anybody ever say "why not" or "how come"? Gotta think outside the box c'mon man.
I have a 2014 limited and had the upgrade pump put on it and i have 54.050 miles on it and the pump was changed at 30.000 and no problems no where on the bike at 54.050.
You are the best out there.

I love my 2019 Limited. It is weird to say that one part of my servicing will be replacing the coolant, but hey...*shrugs*
I recently bought a 2016 limited, and thru U tube eventually my pump is going to fail, I only have 8000 miles on it, but according to other people, I need to keep a close eye on my water pump, and my gauges, because poor manufacturing from Harley Davidson, these water pumps are junk, so I already ordered the new pump, just in case it does go, I still love the motorcycle it has a lot more power than my 2011 road glide did, so if it happens I will replace it. 😊
There's far too many good reasons to have liquid cooling but not enough riders saying that Harley needs it. The Revolution is an astounding engine and is clearly the direction Harley want to take but the traditionalists can't let go of out dated, inferior designs. I don't see any of them demanding Harley build bicycles again

I think Harley has hit the point where they can make a shift, slowly. Customers are aging out and they aren't buying bikes anymore, they will build air cooled motors as long as they can though.
I’m currently looking at a 2015 CVO Street Glide with twin cooling. It only has 1800 miles basically a new bike. Just not sure about the cooling.

Yeah I lost the water pump on my 2016 FLTRU on the way back from sturgis last year. However mine never got the upgraded pump as I never had an issue with it until that trip. Which shocks most people that I got the life out of it that I did? Happened at about 37,000 miles on mine. Got the new larger pump now and was done on my ESP which lmao is about one of three things harley would warranty on my bike because I work/upgrade shit all the time. I will say the couple break downs I had paid for the ESP so I did not lose any money on the ESP but would have gladly if I could have. I hate breakdowns. I did do as you said took an easy cruise to the local dealer an hour and half away. No issues to report from that and now currently 42,000 miles on it.
