hello to everyone, maybe someone has an idea: Omega B, BJ 95, 2,0 16 V 136hp, 176000 KM down, timing belts changed, with water pump, (15.01.16) Thermostat changed a year ago for a few days I have used significantly higher engine temperatures than before, otherwise always around the 93 degrees, now mostly around the 95-99 degrees, possibly just above it, fan runs then also, temperature goes down to approx.96/97 degrees, I set the Omega after driving at approx.99 degrees, ignition everything off, and then sets off the ignition again, shows only 1 second later instead of the just 99 degrees only 95 degrees, or during the ride I come to 98/99 Grand, roll at junction, and then normally continue, also there the temperature goes down immediately to approx.95 degrees and then during the ride again high so can be the temperature sensor, or possibly again the thermostat (1 year old) Thanks for your help,
