Air Cleaner

REMOVAL & INSTALLATION



See Figures 1, 2 and 3

On many early model engines, the air cleaner is located in the center of the engine compartment, directly over the carburetor or throttle body. On some of the 1987 and later engines the air cleaner is more conveniently located toward the front of the engine compartment with an air duct connected to the throttle body. Depending upon the year of the vehicle and which engine it is equipped with, the air cleaner assembly lid may be retained by a wing nut, screws or different types of retaining clamps and/or fasteners.

  1. Unscrew the wing nut or retaining screw(s), or unfasten the clamp(s), as applicable, securing the air cleaner lid, then lift off the housing lid.
