Hi All, What is the normal temperature range for a 3.8 Liter 2013 911 C4S? I recently had the water pump replaced and I think the engine may be running a little warmer now. Thanks! Nate

According to the 991 SIT, you should normally see 194F on the gauge.

"The usual coolant temperature when the engine of the 991 (S) is at operating temperature is 221° F. (105° C); it is reduced to 185° F. (85° C.) during sporty driving and in Sport/Sport Plus mode by opening (energising) the thermostat. This supports a performance-oriented driving style".

"Note: The coolant temperature gauge in the instrument cluster shows 194° F. (90° C) at normal operating temperatures 185° F. - 221° F. (85° C. - 105° C.)".

the 194 is fake. Watch the oil temp.

WEM 911 C4S

RNL is correct. On most modern cars the water temp. gauge is "compensated" to show an average temp within a safe range so that at a quick glance the temp is normal (or not). Oil temp gauges are generally not compensated and show true temp.

As the Porsche document states, if the coolant temp is reading 194F, then it falls within the normal limits of 185-221F. No one is claiming 194 is an accurate current temp.
