So guys, just write to share with you what happened to my bike

Last saturday, took it for a ride. About 5 KM from home i saw the Check engine light blinking (just as a turn signal) - never have i seen that before.

When i got home, turned it off and noticed the fan didnt stay on as usual. Bike was very hot, but mind I say, it did not feel THAT hot between the legs.. probably the same as a not cooled twin cam. I grabbed the computer to connect it to the thundermax software and I could not get the bike to start again.... So i waited for over an hour.. the heat by that time was still present... tank was hot, engine was hot.. everything.. but it fired on.. Thundermax showed 416F engine head temp, overheating, and some ETC errors

Yesterday we started to look for the problem, checked all sensors, oil level, coolant level, and we noticed that the fan was OK, working but was not activating at all when the bike was on... So we disconnected one of the radiator hoses to see if the pump was running the coolant and, No.. no flow at all. We took the pump apart to do some more testing and found out it was not working. I heard these pumps were giving problems all over the board.. so i guess it was just my turn.
We opened it and .. damm... just as the pictures I´ve seen on other forums... very nasty. As we had nothing better to do, we decided to open the faulty coolant pump to see what was going on inside, the result is even nastier. It looks like water/coolant got into the internal components or as if the bike had been flooded.

Evidently this problem had been going for a while until the point of total pump breakdown. Ordered the part yesterday and in case you wonder if harley has done any improvement on this part: nope, Part number is still the same for 2026 bikes as the one that has been used since 2023 for the cvos...

But...I still love my bike.. one of the best rides i´ve had. So.. carry on!

Here are some pictures:

 

Warranty?

 

First I’ve heard of this and I thought my CC bikes have about seen it all

 

Crusty!

 

Yeah that circuit board looks pretty miserable. Hopefully that 416 head temp didn't mess anything further up for you.

 

My thoughts too. Flashing CEL means stop, correct?

 

One possible cause: Overheating conditions that can cause serious engine damage.

 

Yes Brandon..you are right, it means stop. I should totally have. I noticed it just about less than 1 km away from home, but checking my videos it started a little less than 5 km . I know Distance driven under this condition means little as to how much damage could have caused to the engine, but I´m hoping for the best. Will know in a couple of days when i get the parts (pump and sensors) and test it.

 

is it a 2026 he alludes to it but doesn't say

 

Do a cranking compression check and you'll know if you hurt the piston ring sealing or valve sealing. If that's OK and it is not using oil or making unusual noises
you are good to go.
