the procedures and specifications outlined in
the appropriate service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly
and fit. Make certain that the air cleaner is prop -
erly positioned and that the cover is tight. Check
all hoses leading to the air cleaner for tightness.
