Hi Axel,
http://www.wjjeeps.com/faultcodes.htm
"P0118 (M) Engine Coolant
Temperature Circuit High Input
Engine coolant temperature sensor input above the maximum acceptable
voltage." Take it to the Stealer****p and have them diagnose it, it sounds
to
me like the computer's sending too high a voltage to the sensor.
Also, double check the actual coolant level at the radiator cap, cold,
not at the recovery tank.
God Bless America, Bill O|||||||O
