How to install an Oxygen sensor on a 1997 jetta?

Answer 1

the sensor(s) are going to be located near the catalytic converter. you probably have two...One located before the converter and one located right after the converter. you can use either a 20-22 mil box wrench or a really deep socket...most auto stores carry a specific tool for it. You just unscrew the old one pop in the new one...these sensors usually have some anti-seize on them from the parts store already so no need to add any if you don't already have some laying around somewhere.
