Check for coolant loss (possible the water pump seal failed, you can see a tell tale coolant mess at the water pump) We had no end of overheating issues on our recent big trip (Arg - Alaska) . Bleeding the system is a right PITA but neccessary to do it right.
Also check the fan is coming in when it should (another common problem) With a GS911 you can run a fan test and check the temp in real time.
