We're ok to about 250f plus some, if I recall. I would add a couple tablespoons of water wetter to the reservoir and make sure the level is up to the line. I go past the line.
Now I know this is gonna disturb everyone, but I WOULD change the oil often and the filter until the temp goes lower. use amsoil syn and their little filter. Don't do any other oil at this time. Heat is a major problem for even good oil so I would change the oil
My g4's always run cool unless idling at a stupid traffic light or running up a steep mountain section in heat at high rpms but even then it's like 203f and sitting at the light in heat it's not above 212f.
the above is on both the '11 and the '13 in normal humidity as in NOT dry desert stuff. I'm in the Monterey Bay CA, USA area.
