<FONT face="Times New Roman, Times, serif">Can anyone tell me the normal operating temp for a c43 amg I just bought the car and the weather is cold out in ohio and I have no Idea whats a normal winter temp? </FONT>

 

Typically (for most engines anyway) &lt;120 °C is OK (85-110 °C normal, at least for both my 4 Cyl and V8 SUV), over that boils the water from the coolant and overheats. When outside temps &lt; 5 °F, warm the engine a little (~4 minutes)before stepping on it to prevent block/valve head warping.
