Engine Air Cleaner/Filter
The air cleaner and filter are on the driver’s side of the
engine compartment.
To check or replace the air filter:
1. Remove the radiator hose from the resonator channel.
2. Release the tension of the wing screw clamp on the
air intake hose where it attaches to the air cleaner
cover near the top of the engine. Just turn the wing
screw counterclockwise, then detach the hose from
the air cleaner cover.
3. To remove the air cleaner cover, push the hose and
resonator assembly rearward and up, and hold them
out of the way.
