How do you replace the oxygen sensors on a 1996 Chevy Suburban?

To replace the oxygen sensors on a 1996 Chevy Suburban, first, ensure the vehicle is cool and disconnect the negative battery terminal. Locate the oxygen sensors, which are typically found in the exhaust manifold and after the catalytic converter. Use a wrench or an oxygen sensor socket to carefully unscrew the old sensors, then install the new ones by tightening them securely. Finally, reconnect the battery and check for any diagnostic trouble codes before starting the engine.
