Just purchased my first Omega,a 2001 2.2 litre CD auto,and I love it.
I wanted a good towcar and on paper this fits the bill,however it appears to be running quite hot when towing my caravan,temperature goes up to 90 to 100 and if i slow down in traffic the needle touches the red and the temperature light comes on for about 15 seconds before going back down to 80 /85 .
I have changed the thermostat,flushed the radiator and changed the antifreeze,changed the fan sensor.
and added new engine oil and filter. I am not losing any coolant.
Is this the normal running temperature or should i be concerned?
Looking forward to hearing from any of you experts out there.
