I need to know how many sensors are on a 1992 3.1 RS Camaro and where they are located. I heard there is only one locates on the driver side exhaust manifold. Oh and what size wrench should I use to get an exact fit? I heard the make a special socket for it, but I'd rather try it out with a wrench first. Thanks

 

a stuck oxygen sensor is going to fight you enough as-is, don't use a wrench and risk rounding it out. any advance auto or autozone has the correct sensor sockets as part of their loaner tool program. these cars only use one sensor on them, should see it sticking out toward the bottom of the manifold.

 

Should be pointing inboard just after the Y pipe.

 

How much does it cost to be loaned a socket?

 

as i remember it you leave a deposit and get it all back when you return the tool.

 

I couldn't find my socket so used a wrench. It wasn't seized so came out fairly easily. You could try a wrench but if doesn't give way with moderate force buy/borrow the socket.

 

IIRC, advance auto loans out the set of 3 or 4 for about $30, but you get all the money back when you return them
