I after a short ride yesterday it did it again, pushed out about 150 mils of water to just below the low mark when cold. I found the bleed bolt, loosened it and allowed the coolant to drip out for a bit then retightened.
Checked the overflow pipes all are connected correctly.
Looking at the water bottle design, the coolant has to fill the overflow bottle before it can come out of the overflow pipe
Very strange because the motor never seems to be hot when this happens maybe the dealer will find something when I take in.
I notice the fan only runs if the motor is running, it that correct.
Planning on another ride tomorrow, see if it occurs again.
One thing I had not done was check the radiator cap, I could not pressure test it but I did take it off, could not see any problem and gave it a clean and blow out.
