Yes, using an incorrect sealant can potentially poison an oxygen sensor. Certain sealants contain chemicals that can release harmful substances when heated, which may interfere with the sensor's ability to accurately measure oxygen levels in the exhaust. This can lead to erroneous readings and affect engine performance, potentially causing long-term damage to the sensor. It's essential to use sealants specifically recommended for automotive applications to avoid such issues.

Do you put some sealant on coolant sensor thread?

It's generally not necessary to apply sealant to the threads of a coolant sensor, as these sensors are typically designed to create a seal when properly tightened. However, if the manufacturer’s instructions or the specific application suggests it, a small amount of thread sealant may be used to prevent leaks. Always ensure that the sealant is compatible with coolant and does not interfere with the sensor's function. It's best to consult the vehicle's service manual for specific recommendations.

Is a oxygen sensor a thermistor sensor?

No, an oxygen sensor is not a thermistor sensor. An oxygen sensor measures the amount of oxygen in the exhaust gases of a vehicle to help determine the air-fuel ratio.
