Coolant Temp

[Andrew Lundy]

Sean--

Those "thick" lines are labeled in Europe.  They didn't label them here (in
the US) because the conversion to Fahrenheit would have looked a little
strange!!!

The first "thick" line is 90 C (194 F) and the second thick line is 130 C
(266 F).

The coolant temperature will change...it can't hold it's temp that good.
The only thing I can think of for the "climate temp" leveling off is that 90
C is all the higher they calibrated it to read....maybe??

But the temps above or what the gauge is telling you.....you can interpolate
the other lines!!

HTH!!
