The catalytic converter on a 2001 Mercury Mountaineer is located underneath the vehicle, typically positioned between the exhaust manifold and the muffler. It is mounted along the exhaust system, close to the engine, and is usually shielded by a metal cover for protection. To access it, you may need to raise the vehicle and inspect the underside.
On the exhaust pipe, lower, possibly near the catalytic converter.

In a 2001 Mercury Mountaineer, the catalytic converter is located beneath the vehicle, typically between the exhaust manifold and the muffler. It is situated along the exhaust system, near the center of the vehicle, and can be accessed from underneath. For easier identification, it usually has a cylindrical shape and is made of metal. Always ensure the vehicle is safely supported before attempting to inspect or work on the exhaust system.
It is after the last catalytic converter.
On a 1998 Mercury Mountaineer, the oxygen (O2) sensors are located in two main positions: the upstream (pre-catalytic converter) sensors are found on the exhaust manifolds, typically one on each side of the engine, and the downstream (post-catalytic converter) sensors are located after the catalytic converters along the exhaust pipes. To access them, you may need to raise the vehicle for better visibility and reach. Ensure to disconnect the battery before replacing the sensors to avoid any electrical issues.
