2018 Ultra Limited Leak??

[Grego Burke]

I have a 2018 Ultra Limited. I rode about 300 miles in 90 degree + temps yesterday. Once home I noticed a leak from my bike. Did not look like oil more like water. Not leaking now and all fluids seems to be full. What could it be??

Did you check the feel of this liquid?
Any stain / dried fluid lines leading up to a starting point may help to determine cause.
Maybe your neighbor snuck over and as drooling over your bike.

I did and I think it was coolant. Underneath the motor left side towards the front had a small drip. Once the motor cooled I see nothing. It had to happen as it was cooling down. Very light stain on my garage floor this morning.

I've never worked on a liquid cooled motorcycle so this is a question, can you do a pressure check where you add coolant? If so you can possibly trace down any leak location.

 

[Grego Burke]

Going to do that.

Your coolant bottle cap (radiator cap) is loose.Ask Me How I know.

Could be the coolant absorbing the engine heat after stopping and without the cooling effect of riding. Does the water pump have an overflow valve? Could be blowing off the excess coolant and would be perfectly normal.

Thanks everyone. I had 3 others tell me it was the overflow value.

 

[Harttoo]

Yes ,It's coming out the overflow,because the radiator cap is not on tight.

I just checked it and it seems tight
