onko mittari näyttämä 100 c.normaali koneenlämpö ?

tätä teemaa on käsitelty jo aiemminkin, tällaisen oli cee5 kaivanut jenkkifoorumista:


" ...I am a GM Engineer,20+ years. The C5 was my last active project before retiring two years ago , I spent 5 years in it's development....

For later model C5 years:
The low speed cooling fan is commanded on when the coolant temperature reaches 108°C (226°F). It is turned off if the coolant temperature lowers to 104°C (219°F). The high speed cooling fan is commanded on when the coolant temperature reaches 113°C (235°F). It is turned off if the coolant temperature lowers to 108°C (226°F). When the A/C is on and the coolant temperature reaches 85°C (185°F), the low speed cooling fan will be turned on at vehicle speeds less than 56 kPh (35 mph).

For early model years:
Low speed fans come on at 219,high speed fans come on at 228,low speed with a/c on...
IN the summer the car frequently sees 235F. with oil temps reaching 250. This is designed in for emissions reasons, and government compliance.. not for performance or engine longevity.. Aluminum engines and heat are not condusive to heathy engines.. Also heat will cause those with less than 93 octane gas, to ,on occassion, activate knock retard, and cause a decrease in engine performance ...
