Is there a diagram of where an O2 sensor is on a 1996 Chevy Beretta?
There are two of them on a 1996 Beretta. One is mounted in the rear exhaust manifold. You should be able to see it by looking under the hood, straight down the back of the engine. The other is located just before the catalytic converter. Poke your head under the car and look for the big "bubble" in the exhaust pipe closer to the engine.
Where is the engine block drain plug located on a 1996 Chevy Beretta Z26 besides just on the bottom?
can also be done with a open or boxed end wrench, but is harder to do but cheaper than buying a o2 sensor socket. there are 2 o2 sensors on these ( i have one to) you need a special tool looks like a spark plug sockett with a space cut out on one side to accomadate the wires from the sensor not hard to do just a pain in the butt heidi
