yesterday i got a call and arranged the appointment with the mechanic. Just got the car back.
and the odyssey continues ....
Now it seems i have a changed behaviour.
I went for a ride, all good in terms of temps, return and let idle.
Gauge goes up naturally, no fans.
reaches the red zone, and immediatelly full speed cuts in!! The tornado!
and then half speed for a few seconds, i am still not sure this wasn't just the ease off.
then stops.
and then the same over and over again.
Nothing bubbles but everything is freaking hot in the engine compartment.
At least it managed to keep the gauge at the same place. Start of reds. But it couldn't bring it down from there. And today was a cool day with 29 degrees.
The mechanic told me to replace the Colorstat sensor for the gauge.
I have my doubts, but on the other hand i am out of ideas. A 25 minute ride reaching 160km/h and the gauge reached the middle of the 3rd sector. This seems like a nice working sensor to me. I mean, except if a sensor loses track after a certain amount of heat. I don't know.

Oh well, at least i know full speed is working and probably the engine wont blow if i forget to check the gauge.
I am certainly going to scare people in a traffic light though, when this tornado kicks in!

cheers all,
Pan
