I'd be worried if I see the gauge read above 1/2 ... the TS problem on Civic could be the temperature sensor, as this I had replaced on the EG Civic but the temperature gauge was reading lower than normal (instead of higher as TS sees) ... the sensor is essentially a thermistor and could change its characteristic curve over time

The Civic, as all tranverse engine FWD cars, do not have clutch fan. The radiator fan is driven directly by a motor, where power is applied when the thermal switch is activated. One common problem for old cars is worn carbon brush of the motor, where the motor runs but not at full power, causing the engine temperature (as shown by gauge) to rise and dip, depending on driving conditions.

as you mention, the normal temperature gauge readout is less than 1/2 or 1/3 above. mine readout is above 1/2 or one line above, and its firm there. i already replaced my temp sensor as this might be the problem.. still under observation as i ran only from manila to alabang area..
