Dodge Dynasty engine temperature

My dynasty used to keep the engine temperature at
about one third position of the meter and was very
stable. But recently it always droped to only one
sixth position. I mean lower temperature.
There is no other noise or problem with it. Just
want to know if it's normal. Shall I visit a
specialist. My car was 1993 model and 85,000 on it.

Any post will be appreciated.

    Thermostat or coolant temperature sensor may need to be looked at.

    My Dynasty is running on 5 cylinders instead of six. Is there any risk if I continue driving on 5 cylinders ? What will be the bad effect of that on my car example will it give less milage or any other thing like that ?

    Your early response is appreciated.

    Bad effects would be a rough running engine, worse fuel economy.
    All of the unburned fuel would go into the exhaust system and probably clog up the catalytic converter, perhaps in time, blow up the converter.

    I would get it fixed.

    Look for a fouled spark plug, bad spark plug wire, or distributor cap.

    Your voltage of 1/6 is normal for what you see on the gage. The question is why? Your gage only reports what it is told. What the computer understands is that your engine is running a little colder than usual. Therefore, a rich fuel mixture command will be sent to the injectors, a larger injector pulse width greater than 2 milliseconds will be experienced. Warm your engine for about ten minutes and then disconnect the engine coolant temperature sensor. You should experience an RPM change, minor though, then connect it back on. If you don't sense an RPM change when you hook it back up, then replace the sensor with a new one. Best if you obtain it from the dealer, the after market ones aren't as to specifications as was engineered to be. Though, they'll work, just as an eight year old battery can still start a car. The small added expense will assist the look-up tables in the computer program to better adjust for the wear and tear of the age of the engine. And at this point we can't afford to cut corners. Oh! Yes. If you don't sense an RPM change even after a few seconds of disconnection; check for added resistance in the wires and connections. Lastly, have you added any new anti-freeze, replaced the thermostat, changed your driving habits or routines? Something else to keep in mind before diving after the Engine Coolant Temperature Sensor.
