Oxy Sensor question


Roadster90

Recommended Posts

I have not replaced an Oxy Sensor in years - 10 or more probably. I havent really had any great driveability difficulties in probably 10 + years so I am not only forgetful but rusty as well...Anyway, I kind of remember that there were some special characteristics or a different from normal procedure in replacing the oxy sensor as to not pull threads out when changing - should the sensor be removed with the exhaust cold, warm, hot, or ? Thanks for any help with this...

Nic, I rented the correct socket. I replaced mine when the engine was slightly warm. Also, squirted PB Blaster on the threads before I began.

If it was installed with a dab of anti-seize compound on the threads (usually comes that way) it should come right out cold just like a spark plug. If it doesn't budge, then soaking with penetrating oil and heat will be needed.
