Only use Ford or Motorcraft parts. Aftermarket sensors fail way too often. Buy good sensors and do the job once.

apply anti-sleeze to the threads of the new sensor.

Buy an O2 sensor socket ... makes 'em about a thousand times eaisier to take off.... Kragen or NAPA has 'em for very little.

autozone let me use the socket for free

they have more than one 02. are you replacing them all?? if only one is bad, you dont really need to replace them all.

I have 2 sensors.Crawled underneath,cracked the rear one loose.It's the one up closest to the engine that will probably give me hell.What about Bosch brand? I know the Ford dealer will get me for more! Thanx to all for the tips too!!!

Like I said before, I wouldn't use anything other than a Ford or Motorcraft sensor in my Fords. I work at a large independent repair shop & we're super-picky about the emissions/EFI parts we'll use. We've tried them all and no aftermarket parts(including bosch) work as well or as long as O.E. parts. Oddly enough, Bosch makes a lot of O.E. oxygen sensors for a lot of car manufacturers, but their aftermarket stuff still isn't as reliable.

Hey anyone know where to get the dummy o2 sensors?? I need one to race and my jeep is obd2. For now it runs fine w/o a cat and regular sensor but just in case.
