Default Any advice on changing 02 Sensors?

I'm swapping out all 4 o2 sensors today (I think). Any tips on doing this? I've gotten the appropriate tool from AutoZone, but I still need to pick up some extensions for my ratchet. The lower ones should be easy- but I'm concered about reaching the primaries....

Default Yes:

I've done it so many times now;

Get PB Blaster. Soak em' up.

Get a 3/8" rachet,
Get an 18" extension
Get a 3/8---->1/2" adapter to fit from the extension to the O2 socket

Passenger side is easy

Driverside you need all the tools you bought.

Standing in front of the car lean over the engine an look down between the firewall and the engine. Place your O2 socket on the sensor so that the socket is pointing at your knees.
Put the 3/8----1/2" adapter in the socket first, then put the 18" extension on to your wrench.

Put your wrench end by the passenger side downpipe and come towards the driverside with the extension. Mate up the extension and the adapter/ O2 socket. Break it free.

Home run. Pat yourself on the back for saving yourself a few $hundred dollars. Pay me half. Just kidding.

Default Thank you so much!

Hope I won't need PB blaster as all of the 02s were pulled within the last 6 months (swapping to piggies)

Default Where were you two weeks ago! Good write-up I had to figure it out as I went. This would have

saved me a few trips to AZ.
