I will be replacing the oxygen sensor on the cat tomorrow. Anything I should know about the install? or is it pretty straight forward?

thanks

 

Just replaced mine last week. Easy fix. Make sure you have something with a lot of leverage, you'll need it. 10 minutes with the right tool. I just cut the wires off the old one so I could get a socket on it. Almost impossible to get off with a wrench.

 

Be sure new one has antisieze on the threads they are pain to remove if installed with out it.

 

right on thanks guys

 

Replaced mine Friday... drove it home from work.. kept it running.. cut the wires and used a socket and a breaker bar.. between the heat and the leverage she popped right out..

 

There is a special tool made called an O2 Sensor Socket (pretty genius name ) which has a "slice" down the side of the socket to accommodate the wires so you don't have to cut them. Or you can just use an open end 7/8" wrench. Either way should would. I would use PB Blaster to be safe though. One time when I was getting an O2 sensor from the junkyard, it was on real tight and I used my foot to push the wrench and it tore the whole cat apart. The O2 was still in the threads and the cat had a big hole in it. So if your cat is real rusty, use some PB Blaster.
