O2 sensor removal

[Mad Mike]

I can't figure out how to search the old bb archives so.... I am unable to remove my o2 sensor. Have soaked it for days with PB blaster and when I tried to remove it with the slotted socket the socket spread open causing it to slip and partially round the corners on the sensor. Heated the bung with a propane torch and tried again but same thing happened. Was thinking of just buying a deep 7/8 inch socket cutting off the wires on top of the sensor and applying some torque so to speak. Anyone have any other ideas? Thanks.

Try a big ****ing wrench.

Re: O2 sensor removal

Mike you've got exactly the right idea. I wrestled with the exact same problem and had the same experience you did, right down to the side-splitting O2 Sensor Socket. I bought a bunch of tools for this and they all failed. Snap On O2 Sensor Socket failed, MAC tools O2 Sensor Socket failed. 22mm closed end wrench, failed. 7/8" wrench, failed. The good news is - you've already got the solution! Get that deep 7/8 Impact Socket and it will offer so much brute force and grip it will turn that sensor right out. The only drawback is when I did mine, I had to COMPLETELY bust off the body of the O2 sensor in order to fit the socket over it.

small price to pay IMO. Toss a dab of never sieze on the new one before installation. It'll make removal easier the next time.

Heat with an acetylene torch should loosen it up.

BTDT.

one more thing to try.
Put a hose clamp around the O2 socket to hold it from spreading.

Last resort cut he wires as close as you can adn use a deep well socket on it.

Both methods have worked for me.

I have had good luck removing the battery, cutting the wires, using a close 22mm in combination with another Big F'n wrench.

The BF'n wrench on the end of another BF'n wrench technique rawks!

Re: O2 sensor removal

heat, socket, and impact wrench.

or if you are changing it through the wheel well: heat, boxed end wrench, and a lot of cussing.:rotf:

Ok, got it out. Cut the wires, knocked off the top of the old sensor, PB Blaster, heat, 7/8 deep socket, 1/2 wobble extension, ratchet and 2 ' of pipe. POP! Came right out. Thanks to all!

Re: O2 sensor removal

since my socket also has the hex end i cut the plug off the sensor wire and poked it throught the 1/2 socket hole then used a BIG wrench on the socket... i fixed the wire later and reused the o2 sens

hope it helps
