The thermo switch on a Chevy Optra is located in different places depending on the model year. According to a user on a forum, for 2005 and older models, the thermo switch is usually located at the engine on the upper radiator hose, inside the thermostat housing. However, for 2006 and newer models, the location of the thermo switch was changed to the driver’s side, towards the back of the engine. It is important to note that this information is based on user experiences and may vary depending on the specific model and year of the Chevy Optra.

Where is the temperature switch located?
The ECT sensor is often located on the engine block, usually near the thermostat housing. On some engines, it may be located on the intake manifold. The sensor measures the temperature of the coolant and sends a signal to the computer. The computer uses this information to adjust the ignition timing and fuel mixture.
What happens if oxygen sensor fails?
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
What is the symptoms of a bad oxygen sensor?
First, what are the signs an O2 sensor may have gone bad?
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.

What happens when a temperature sensor goes bad?
A malfunctioning coolant temperature sensor may send an incorrect “cold” signal to the ECU, tricking it into believing the engine isn’t hot yet. The ECU will then adjust the fuel injection, ignition timing, and variable valve timing, further raising the engine’s temperature and causing it to overheat.
Where is the thermo coolant fan switch located?
radiator assembly
Generally mounted on the radiator assembly.
What happens if you unplug the coolant temp sensor?
If you are unplugging your vehicle’s coolant temperature sensor, you will definitely run into some problems. you will set a trouble code, check engine light on, radiator cooling fan should come on. Don’t drive car with the sensor disconnected.
Where is the oxygen sensor on a Chevy Optra?
The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter.
Where is the coolant temperature sensor located?
Where is the Coolant Temperature Sensor located? The coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath the air intake pipe.
