I have replaced my coolant temperature sensor 2x now. Is it possible that the parts are defective or could there be a short somewhere causing them to go bad? An I doing it wrong? What are the instructions?

It is unlikely that you are doing it wrong. However, if you are putting them in and the issue is there immediately again then it is unlikely that the sensor is the issue. However, the way this sounds is that you put the sensor in and it seems fine for a while then it fails again? If that is the case then you are getting faulty sensors as it is highly unlikely that something is shorting the sensor out.

Here are a couple guides that will help with this:

Below you will find the process from the manual that will give the remaining detail needed to finish this.

Please let us know if you have questions with this.
