Default O2 Sensor Replace

Replacing my sensors today. I have read in RAVE that an anti-seize compound should be used but my sensor kit didn't come with any and I can't find any recommendations in RAVE or on this forum. So is there a specific kind to use?

Also, these sensor wires don't look nearly as insulated as the originals. Any thoughts on wrapping them?

Also, I don't know why people complain about the D2 being cramped to work on. There's plenty of room when you remove the engine!

Old sensors appear to have a lot more insulation?

Puny insulation!

I used anti seize, but leave the 2 threads nearest the probe dry. Don't use a lot, use a brush to put on a light coat.

In the second picture, it looks as though a couple of the wires have pushed out of the new gray plug housing. Those blue rubber seals should be flush with the connector housing. It's very easy to push these plug terminals out, and seeing the blue seals moved outward...makes me believe this may have happen. You will have a poor connection and the possibility of moisture entering the connection, if not repaired correctly.

Yes, removing the engine is the only way to go!...lol.

Good catch on the connector Brian!

Re: Anti-Seize try Permatex Copper # 09128 it has a very decent high heat range and you can get it at any Advance, Auto Zone, Napa, etc.
And as mentioned you don't need a ton on the threads.

The sensors came that way. I took a closer look at one straight out of the package and they all look like this. Should I contact Atlantic British?

They came like that? Wow. The new sensors should already have anti-seize applied, thats why they have that plastic cover on the threads. To keep the stuff on the threads and not all over the packaging.

On closer inspection, they did have anti-seize on them. But the blue plugs were out on each of them. Can I just push them in and be good or should I contact AB?

Yes you can push them in and it will be fine. Just make sure the terminal end is flush with the plug housing before you plug it in. We get this all the time at work. Some of them even come with a Do it yourself plug wiring kit so no plug on it at all! The main thing is to watch out for an o2 sensor code when you run it. It could mean that the connection isnt good enough. As for the shielding, you could just cut the wires and pull the case off the old one and swap it but I wouldnt worry. zip tie the wires that arent insulated up away from the pipe and your good to go!

That is just plain sad that you received them in that condition. But, yes...you can push the rubbers in...but, only after confirming that the terminals are snapped securely in the plug housing. The wire shouldn't move out of the plug housing, when gently pulled...if it does...try pushing it back into the terminal socket until you hear a faint snap. If you don't hear a faint snap, then pull it completely out and check the locking tab on terminal end, if it is flush with the rest of the terminal, it can be bent back into position (flared outward some) and reinserted. If you can not get the terminal to lock into the plug connector housing...l'd ship them back to supplier.

Brian.
