Oxygen Sensor Question

[brian2sun]

Uhhh, that's their old logo....you are a tough sell, my friend.

Well, that settles it. For the record, I was 99% sure all of them were Densos when we started talking about it, I just was wondering if anyone's actually said "Denso", but that logo confims it. Thanks for the good info Durk.

Look at the nuts. If they are original and you see any salt, they will be totally corroded. If it looks like they would actually come off in one piece with a wrench, the sensor is not that old. Does not apply in the desert. Should apply in OR.

What size nuts does that take? I am replacing my O2 sensor and the nuts look like crap and I am going to replace them. Does anyone know what size they are? I have an 2000 V6 4R with 4WD.

Good luck. I used like 3 different size sockets (getting smaller each time) and then kept ratcheting down with a small pair of vise-grips. Eventually they just crumbled into pieces. The good news is the studs are a whole lot harder than the nuts, and cleaned up very nicely. Still a medium PIA. But that's why I recommend sticking to stainless. They are softer and crumble better. I have 50K on my front replacement, so in two years or so I'll find out if copper anti-seize helps.

Rock Auto's website has the Denso and says it's the OEM part (2344162 for a 98, 4WD, auto, upstream sensor). It's like $68.
