Hi all...

i have a problem with my coolant...lately its very high on the meter in the dash....its between the "N" and red....normally it was on the "M"..and sometimes on the "R" with hot wheater, trafficjam or driving fast..

when i drive @60mph in 5 then its between "N" and red....
but in the same speed in 4 its on the downside of the "N"...

the fans are working ok...turning on...and later on turning off like a normal cossie...
i have a bailey headertank/swirlpot....the tank is half full of coolant...

i thought about the thermostat..or the temp sensor....
someone said to me about the headgasket....but i have no messy stuff in the headertank...no fuel smell in the tank also....no white stuff under the oilcap....

does someone have a clue...

Thanks...
