The pressures depend on the temperatures so it is not possible to give "normal" temperatures. The pressures change with the outdoor and indoor temperatures. You need to be EPA certified to attach gauges to the unit to check the pressures.
Lo
195F or 90C.
Normal operating Temp is about 87C
100 Celsius which = 212 Degree Fahrenheit
The normal operating temp for any Mercedes is between 80°C and 100°C (the next line after 80°) Anything over 100° and you should have it checked out. Mercedes are different, in that, the temp gauge is constantly moving because it provides true engine temp data... not just (normal) or stuck in the middle of the gauge.
Needle in gauge should be midway between the 80 mark and the mark just above it.
Probably around 210 Fahrenheit
Typically 80 - 85 degrees c. (Just slightly above the 80 mark on your temperature gauge)
the normal operating temperature for cars is around 190 degrees.
Oxygen IS a gas at normal temperatures and pressures
Using a Mercedes 190D-2.2 as an example; Normal operating temperature is around 200 degrees Fahrenheit. Keep in mind that the clutch operated radiator cooling fan is designed to shut off when the coolant temperature reaches 212 degrees Fahrenheit or 100 degrees Celsius and below. SPKB..
