My o2 sensor arrived and i attempted to change it today... fuarkk what size spanner is it? my toolset only went up to 19mm and tried vice grips but no luck. had to re-clip it and leave it. forgot to disconnect battery before as well. it's on pretty tight, any suggestions? can i spray wd40 on that area?
Get a shifter, 18inch 20inch are big enough. Shifter needs to be on tight and just needs a bang and it'll come off.
Yea you can spray wd40 there. Just dont slip and strip the bolt lol
