I have my truck going up the sierra mountains twice a month and everytime the water climbs in the coolant tank.
First time I saw it, yea my eyes got real big but it does it every time I go. Like I said open up the cap slow and you will watch the coolant level drop to the same level you are used to seeing in the valley or where ever you normally live.
My truck has no issues eot/ect is 3-5 degrees healthy as a horse, but climbing 5000 feet makes a difference, atmospheric pressure is lower. 10,000 feet is a hell of a change. Lower your coolant level and it won't blow out, there is less atmospheric pressure: (your water is getting bigger w/lack of pressure to make it as easy for me to explain)
Again you are fine! Mark...............
