Hi all:
the following happens with a 2002 307 SW (1600 cc): the temp gauge used to run steady at 90 degrees (Celsius, approx 194 Fahrenheit) when the motor was warm. All of a sudden the temperature indication has dropped to 75 (Celsius) when warm. The temp instrument seems ok. The dealer cannot find anything wrong with the car. But obviously something MUST BE wrong. Can it be a faulty thermostat instructing more coolant flow through the system? Please suggest things to look for. TIA,
Nikolas
ps. The drop in temp indication cannot be attributed to weather conditions, which have remained steady over the period of this change. The coolant /oil has not been replaced either.
