02sensors on a 1997 mazda 626

could you please tell me where those are located on the car and how do you change them out? Is there a special tool to change them out with and how many are on the car

They should be located at your exhaust junction, if you have a V6 you more than likely have 2 you just have to look for them, but most 2 or 3 sensor set ups have one after-cat they will be threaded in to your exhaust. Most of them can be removed with a wrench.

I agree. If not, an auto parts store sells the special socket to do the job. About $15.
