Put a socket on it, unscrew it and screw in the new one. Disconnect wire first of course and reconnect on the new one. Use a bit of anti seize on the new one. More or less a spark plug type device. No big deal.

They make a special 02 sensor socket, but in at least my 97 3.0, the
02 sensor is readily accessible underneath with a closed-end wrench.
That will slip on easily after you disconnect the wire. That's all I used.
My 02 sensor came pre-lubed with anti-seize. Slam dunk.
I replaced both 02 sensors in my 94 Grand Marquis 4.6 and both were
a pain in the butt (and back, and knuckles). Aerostar was a comparative
breeze.

No. There's no easy way to do it. You will lose some skin!

If all else failed, a big pipe wrench will do nicely, and don't be shy about it.

I've never had any problems using an open-ended or adjustable wrench. I also happen to have some really large box-end wrenchs that fit the hex. Those sizes will usually slip right over the connector so you can thread the wires through it and place it completely over the hex.

The best sensors for these are generally Denso or Bosch. The dealer is expensive, but see if you can find those through a local parts supplier. The front and rear sensors may be different. Just wondering, are you replaceing them due to age, or are you experiencing a problem that might be associated.

Question 02 sensor

I'm replacing them because the van has 88,000 miles. It runs fine but isn't it a good idea to replace them after 50,000 miiles anyway?

Absolutely. Old worn out sensors cause poor fuel economy and other problems. It is better to avoid problems are replace the sensor than to have to replace other more expensive components and a sensor.

try one of our site sponsors RockAuto dot com....
easy to use site...knowlegable phone help if needed...tough to beat prices and fast shipping delivery by multi choice methods

still miss the old time local auto parts counter stores with the walking live parts cataloges guys and engine specialists behind the counter...plus there used to be free coffee and a chair to set in on rainy days and shoot the bs....

now....sad...i won't talk about it...makes my skin crawl to walk into one of these new parts stores?
