Hey everyone I came across something really cool. When I had some exhaust work done I let myself be talked into an O2... Duuuh it'* probably a Bosch. Today I pick up a Delco and need to put it in. In talking to the man about putting it in and not thinking the cresent wrench will have enough swing room....he says..crows foot. Hmmmm

A 7/8 inch crow foot, 2 foot extension and my favorite rachet took care of the situation in record time. I wanted to pass this tip on to forum.

i had to look that one up...

good idea!!

crows foot is OK as long as its not seized.

I use a ratchet wrench.

Rent the proper tool from AutoZone.

Those crows feet can round off the flats on the sensor. With the socket from AutoZone, you're grabbing all six flats, opposed to only two.

I went at it smoking hot, just cruised back from Randy'*. Plus I know it had been out w/in the month. I agree on the right tool, wanted to share for the in a pinch situation.

The tool shown in the service manual is a crows foot socket. Are you describing one that is like a flare nut wrench?

Guys...he'* got Foamy as a mascot for a reason...lol Heat that baby up and pop it right out.

Suggestion and future note to stupid self: when you take out old O2...put somewhere besides strut tower you are going to lean forearm on.

No, it'* a 1/2" drive socket, with a slit in the wall of the socket. That slit accomodates the wires from the sensor to hang off to the side, as the socket locks fully on top of the sensor. It'* a handy little tool.

Interesting. Sounds like someoneone could make one by taking a Dremel tool and cutoff wheel to a deep well socket??
