    O Sensor Removal

    I have a '96 GMC K1500 4x4 that needs it's Oxygen Sensors changed. All 4 of them are really seized into place and there's not a whole bunch of room to get much of a wrench on them. I'm looking for some suggestions on a workable solution that won't cause me to ruin the exhaust pipe.

    I get confused once numbers get bigger than I can count on my appendages. I'm only good up to 21!
    one quarter turn before something breaks is a good torque spec.

    Thanks, I'd been struggling with them the other day with wrenches only 'cause I was out of Oxygen and low on Acetylene. I got nowhere with that approach but fixed the welding gas problem this morning, so now I've got full bottles for my next attempt. Thursday is supposed to be around +10 C, so it won't be too bad spending some time on my back taking out those 4 sensors - I'll get some fresh air while I'm at it..., bonus!!

    run the truck until its good and warm...
    pour water on the bung, but not the sensor.
    it shocks the metal and will allow you to remove
    them with ease
