I would like to replace the O2 sensor in my 91 loyale 4wd non turbo wagon

Whats the procedure to get it out without ripping the threads up?

should I but the special socket or will a box wrench work well enough?

should I put anti seize on the new one?

thanks

 

 

I'm getting a 3-2 light pulse....car seems to run okay,,,,maybe a tiny bit rough...anyone know?

I've had more lights come on this sub than all others I've owned since 11/1979

 

thanks

02 sensor; replace if you can. Don't sweat it if you can't. Pretty cheap item for a single wire generic O2 sensor.

will gas mileage suffer?

 

do you need a special wrench?

What kind of cost do you think?

 

thanks

Yes, probably... that is if you mean if you don't replace it.

22mm wrench; or there is also a special socket that has a cutout for the wire to slip through.

 

$25-35

 

Edit - Oh, and don't just go yanking it out. They tend to stick in their bungs, and then the threads just rip off and you have to run a thread chaser though its... well, its bunghole. Follow removal procedure in manual. end edit

I bought the stupid special socket.... used it a grand total of twice now.
