o2 sensor on a 2002 p38, what tools?

[jmonsrvr]

Hello, will be changing front o2 sensors on a 2002 p38 in the next couple of days and was wondering if i needed any special tools (spanners) for this. Can someone please tell me what I will need to change these out? Is it just a spanner? if so what size and style?

Thanks

You can usually 'rent' them for free at most auto part stores like AutoZone etc with a deposit. The O2 sensor socket is deep with a cut-out along one side accomodate the wire that comes out of the sensor, looks like this http://www.4x4xplor.com/images/O2S/DSC00424.jpg

That being said, I just changed all mine in my '98 with a big crescent wrench, only took a few minutes.
