No codes, no warning light, you hear the fans, there is water in it that is (at least barely) in the operating range).  Sounds like it's working to me here in the bleacher seats.

My limited experience with the water cooled bikes has suggested an incorrect stereotype or misperception held by some.  Just because HD has added this small bit of water cooling in now way means these bikes still are not hot.  The water cooling is a band aid on what has been the continuing issue of HD sending out bikes that can get hot enough to be uncomfortable in normal use and sometimes hot enough to cause injury to person or clothes.

I know the bike is still hot but there was considerable difference in the heat between my 13 CVO and my 16 CVO. The 16 being cooler and not uncomfortable to ride.

I guess I will add a couple ounces of coolant and call it good then!

Thanks for the info

I have 2015 CVO Ultra, water pump failed at 60,000kms, I know of 2 others that I ride with that have also failed, one a 2015 103 Ultra, it failed at 14,000kms, the other a 2014 103 Ultra failed at 30,000. No explanation as to why/how just replaced under warranty.

I would think that on a working system the fluid would be much hotter if the water is circulating. If the water is not circulating it would be warm but not hot.  Do you have any idea if the water was hot? I am not saying stick your finger in the water but you should be able to tell.

Read in my 14 electrical diagnostic manual that you can test cooling fan and water pump operation by doing the following (bike can be hot or cold):

Turn run switch to run (do not start bike)

Roll throttle to WOT position and hold until fans run, then roll back throttle to idle (takes a couple seconds for fans to come on after holding to WOT)

Both fans will run as well as water pump

To stop test, turn run switch to off

Can you see the water moving?

Can you see the water moving?

NOPE!!!!! I just keep an eye on my fluid level and ride it. I did lose a water pump at 38K on my way back from Alaska. Replaced under warranty and so far all is good.

A friend told me about the manual activation of the cooling system using the throttle (I wish they had a switch).  I use it after stopping from a long ride and let it run for a few minutes until the air coming off the fans is tolerable.

Good job Don helping a member on the road.

Few times a year someone still finds my place on the way to or from somewhere.  Gotta help when we can.

Can you limp home when you get a warning light or do you have to stop?

I figured you could limp home, I mean the bike was air cooled before and they are only liquid cooling the exhaust ports in the heads BUT the owners manual says if the light comes on shut the bike down immediately and call your local HD service center.

Just came back from Upstate NY/VT. A friend up from SC had his '15 SESG throw water temp and engine lights Sunday (after every possible dealer was closed) on our way to NH. He let the bike cool down and we called a tech we knew and reset codes. Local dealer closed on Mondays, and so we stayed over and took ferry back to NY and yes, it was the water pump (by the time we got to the dealer, the engine oil light also came on along with the others coming back on).

The warranty expired in May but the MoCo covered it. There wasn't one in stock in the Northeast, closest was overnighted from MD. The dealer said it's a $400 part, was $500 with install so no one stocks it. He did offer to swap out from a 2K used bike he had on hand to get us back on the road but our friend wanted a brandy new one.

Are they installing a new one that may fail or are they getting a new improved version. I ask as years ago they had petcocks failing on new bikes at the time and mine was one. So I made them install an aftermarket one because they said none available and I didn't want to wait for another that would fail also. Hope you get it taken care of.

Well when Twolane started this thread I started looking around. It seems that Harley is using Dexcool in our bikes. That is most likely what caused the problem. I have since changed out my Dexcool for Engine Ice. I just got back from a 7K trip out west and had absolutely no problems. I am actually running more oil pressure all over the RPM range. Only 4 to 8 pounds but the bike has more pressure. It also seems like the bike is running cooler.
