GM calls the pellets but all the same.. GM PART#3634621.
Like it or not its the way it is.. I am not saying that it should be that way. Jerry I agree it should not ever leak. But then again tons of things that should not be the way they are..
But being that way things get made today you can fight the good fight and waste your time or take one oz of preventive maintenance and never worry about the issue.
I am betting that in time you will see pump failures, then its going to be about adding a new item to lubricate the pump.. See this in cars as well..
Dex cool used in other application had some major issues,.. so out comes the next greatest coolant.. Round and round it goes..
First hand dealing with a customer that bought a 15 CVO , he has delt with the dealer now for a extremely little stain near a connection. It would leak as it cooled down. He feels the same way it should not do this. However dealer's ( yes 3) will not warranty it as it stated ok even to HD tech dept. So you have a 45,000 dollar bike and it has an issue. One would think they would correct it.. HD is new to this so maybe in time more updates. But for a dealer they have stock parts to swap and that is it. If they swap them and it still does it well now that is normal

1 oz alumaseal. Problem solved. That simple , he has spent 3 months dealing with it.. Maybe its just too simple or some want to fight about the rights and wrong.. cannot tell you.. But if I owned one I would do it right out the gate and never worry about it.
