new o2 sensor for 2002 ox66 250

[tobias pardue]

just ordered a bunch of new parts for my engines and when i opened the package noticed that the o2 sensors had something like grease on the threads which spread to the sensitive protion of the sensor. any problems with this?? should i clean them before install and if so with what? thanks in advance.

just wipe it off wont hurt anything. the sensor is located beneath that protective metal shield with the holes in it. make sure you use the correct tool and torque when replacing the sensor in the holder.
