I just completed a change of the O2 Sensors for 01 Discovery. I sprayed with PB Nut Blaster about 30 minutes before the procedure.

I used this tool from Amazon...
The sizing was perfect and the curved handle made it simple to reach all 4. I highly recommend it!

Getting those connecters apart is not always the easiest, but not terrible.

I am a novice when it comes to cars. I did the 4, on my back, in about an hour.

I bought all 4 at Rock Auto for 200 bucks. So for 200 plus a 20 dollar tool, I am very happy.

Took it back to Autozone after I was done and my codes are no longer there.

 

Hey Matt - I'm in the Charlotte area and need to do this job, want to sell or loan the tool?
Thanks
John

 

wish i would have seen this sooner. i bought the tool from atlantic british and there is no leverage....handle is 3" long.

 

Reading the Amazon reviews, many claim the tool is breaking...obviously yours did not, but just FYI

 

Is this the tool you bought? You know you're supposed to use your socket wrench in the square hole, right?

 

lol, yes

I was wondering what tool he was talking about.

 

Best tool to remove an 02 sensor if you're a real man:

 

Guys all you need is a 7/8th's wrench, pb blaster, and some stank.
