Where is the engine air filter on a 2002 Mercury Sable GS?
The engine air filter on a 2002 Mercury Sable GS is located in a plastic housing on top of the engine, near the front. It's usually a relatively easy-to-access location. You'll likely see a large rectangular or sometimes slightly cylindrical plastic box with a few easily removable clips or screws. To be certain, consult your owner's manual; it will have a diagram showing its exact location.
