O2 Sensors

Hi,

How difficult is it to change these? I'm getting the odd error code from the "upstream" one so thinking about changing both.

I have a V8.

Thanks Pedro,

I was wondering if because where they are, and getting heated up all the time how easy is it to get them undone?

Cheers

The sensors themselves are easy enough to undo. Use a 7/8" open ender & a penetrating release agent (Bolt-Off works very well).
If thread begins to bind, screw back slightly & then continue removal - standard practice.
The major problem I found was; (a) releasing the electrical connector, however
(b) re-connecting the electrical connector was a real PITA.

Another thing to look forward to then!

Thanks for the advice.
