Oxyen sensor gasket.

[Bad_dude]

Hey guys,
I just bought a new Denso O2 sensor from Rockauto, freaking super fast shipping. Ordered Sunday and got it in the mail today. I look at the sensor and it has like an aluminum washer already on it. Is that the same as the outer gasket in the diagram linked below? It's the number 10 in the diagram.

I am going to replace it tomorrow and don't want to do it missing that gasket.
Any one replaced theirs and had to buy the gasket separately?
Thanks.

The washer on it is part # 10

Thanks buddy, I guess I don't need it then. Why do they call it a gasket when it's a washer? Very confusing.

[Chris2388]

I never understood why they call it that.

It ends up crushing creating a perfect seal against both metal parts. Same concept as drain bolt crush washers and banjo fitting crush washers for fuel and brake lines.

Dude,
I thought I had the O2 Sensor socket but it turns out not. What size wrench could I use with it? 22mm?

Thanks.

You'll need a 22mm wrench or an adj'able that can open to 22mm or 7/8"

I am going to see if Autozone would lend me one tomorrow morning. Would an open wrench works if I soak it good?
So you guys take off the heat shield before remove the sensor? Or would it work without?
Thanks.

Yes. That's generally exactly what I use. You have to remove the shield to use the wrench, but not for the socket.

That Denso sensor I just bought, it has a brown little grease package. What is that? Antiseize or thread locker? Or some kind of oil? Should I just use the usual silver antiseize?
Thanks.

It's anti-sieze, use it.

i wouldnt even worry about tightening it down real tight with a wrench or anything... cause if u do... and it doesnt get changed for a long time(which more of the time it doesnt) its real hard to get out... i would just see if you can get the old one out... and if u can just tighten it as much as u can with your hand

He's asking about taking it OFF.

That's a bad idea. You need to tighten it to crush the washer so it seals. Tighten it to crush the seal and that's it.

The connector I got is female. Like the link below.

The heat shield, I got the 3 bolts off but it stuck on the silver metal to the right next to the alternator. Should I just bend that metal plate to remove the heat shield? It looks like the manual show the O2 removal socket and not taking the shield off. Also the manual says 33 ft lb.
Thanks guys, I always ask many questions before any job to make sure it's a success. So far I had good luck. I guess b/c I am unemployed still and can't afford to mess up and have it repair.
