Car won't reach operating temperature

처리 내용

The thermostat would have been my first guess too. It doesn't need a sealing ring, the housing will slightly clamp it when you put it back together. It is entirely possible that the temperature sensor has 'drifted' and is reading lower than the genuine temperature. I have experienced this more than once in my own cars. It's worth as try as they're usually neither expensive nor difficult to change. To verify the actual engine temperature, check if the top hose to the radiator is hot after a drive. Thermostats normally open at around 80-90°C and the hose will only get hot once the thermostat has opened.
