This O2 sensor is kicking my butt

[demarpaint]

Wish I could but right now there isn't any room to add a pipe over the end of the ratchet. Might try and jack it up a few more inches.

Here's another time where a lift makes all the difference in the world! I'd get it higher, then the one minute trick with a nice 6 point socket on a 3/4" breaker bar with a pipe should do it. Even a good 1/2" breaker bar on a pipe should do the trick.

You need heat. Also prepare for the threads in the pipe to be destroyed after you get it out.

A lift would make all the difference here. Plenty of room for leverage and long breaker bars!

you might have to drop the exhaust system.

you might have to drop the exhaust system.

I'll take it to a shop first. Don't want to deal with 20 year old exhaust.

This morning I decided to drive both left wheels on the ramps but that still wasn't enough. Jacked up some more from the axle.

I now have a 4' extension on the socket wrench, but still no go. Will have to try more heat.

 

[MSCH]

yeah, good luck on removing anything intact in a 20 year old exhaust system

If it’s that tight, your really need it glowing red hot all around the sensor bung. Even then you’re possibly pulling the threads out with it. Just get it turning and work it back and forth, spraying penetrant and turning and working it all while it’s hot. If the threads are messed up you may be able to find a thread chaser and get it good enough.

Got it red hot and it finally let go. YE HAW! Doesn't look like if pulled out the threads. May have to get a chaser to clean them up a bit.

Jolting with some kind of impact device usually works well.That and tools with very little flex.Amazing the effectiveness of impact sockets over regular sockets.Congrats.

If you can get your foot on the wrench, sometimes that's the best way to really reef on it.

Got this Lisle thread chaser to clean up the threads.

Then the new sensor went in easy.

Nice! Mission accomplished.

When you finally break something loose, that's our Woodstock
Glad you got it done

Congratulations!

If that is that standard M20 x 1.5 o2 sensor thread - it also works on any 7317 size oil filters as well.

Good work on getting it out!

I work on alot of those vans, most around 10 years newer, the Illinois state fleet has a gazillion of them, all with the 5.4. I haven't specifically seen a 2003 in a while but on the '12-13-14 versions the quickest way I've found us to just pop the doghouse off inside and it's wide open access can get right to it.

Most are M18 not M20 thread

I can imagine you made up multiple words for that project under your breath -- or even out loud at times.

Easiest way to do this is to cut off the pigtail and install a boxed end wrench over the old O2 sensor. Install a ball joint seperator fork on your impact wrench, and then apply it over the free end of the boxed end wrench. The combination of vibration and impact force will break loose the most difficult O2 sensors.
