I am putting in new O2 Sensors, when I picked up from the dealer I was also given some O2 crush washers.

The O2 sensors themselves already have washers on them, wasnt sure if I am suppose to put on the crush washers also? I dont remember seeing them when I took the original sensors off.

Any thoughts? Thanks!

Oh, also the manual does not state anything about using crush washers.

 

Never mind, didnt need them.....
