How do you replace Rodeo oxygen sensors?

They just screw into the exhaust pipe. There are clips that keep the electrical connectors in place, you will have to pry those out, but it should not be a problem. Then all you do is screw the new one back in, and press the clip back into the hole for the elec. connection

Well, i am in the process of changing the sensor as we speak...and i am dirty and hot (yuma, september, over 100 degrees Fahrenheit, shoot me).

I bought my new sensor from Autozone where they were about 50-55 dollars. A sensor connected to a cable with 4 loose wires and a few more parts which would complete the plug (which you build yourself).

My cables from my sensor lead up to a connector which had a perfect fitting plug on it...which was different that the new one though...so replacement in unavoidable.

I just can't get to the rest of the plug to fit the new connectors on. there is some sort of cover (metal, sharp edges) covering the cables. So, i am now off to remove such plate and get to the cable to place new connectors...

Don't do it yourself but pay a mechanic 40 bucks...that's what it's worth.

First guy was right, they just screw in and out. Go back to autozone or checkerauto and you can rent an "oxygen sensor" wrench/ratchet kit. (once you return the kit autozone will refund all your rent money). The kit comes with a dozen different sized and shaped sockets that will fit over your oxygen sensor to help pull them out easy. (my oxygen sensors were covered with dirt that I had to scrape off first, because I go off roading a lot). Make sure you buy the oxygen sensors that already come with the attachment clip for the wires (this will save you lots of time and frustrations) they're only a few dollars more. Before you screw the new oxygen sensor back into place, you should probably put some RTV sealant around the washer. You can get that at autozone too. It comes in a tube for a few dollars. Make sure you get the RTV sealant marked "sensor safe" or "wont harm oxygen sensors" and also that it has a high heat tolerance.
