I was told that you should replace it when the car's at operating temperature when it's easier to remove. However, just like spark plugs, I am under the impression that if I do it while the car's warm, that when it cools, the metal that contracts will tighten around the sensor and mess up the threads. Can anyone clarify for me? Thanks in advance. Replys:
