of dirt entering the engine when you remove the filter.

the key.
2. Open the hood.
3. Check the air-cleaner body for damage, which could
cause an air leak.. Check the whole intake system for
leaks, damage, or loose hose clamps. Replace of repair
and damaged components.
4. Release the latches on the air cleaner and pull the
air-cleaner cover off the air-cleaner body (
Figure 35 ).

body (

side of the body.
Important:
Do not attempt to clean the primary
filter.
2. Inspect the new filter(s) for damage by looking into the
filter while shining a bright light on the outside of the
filter. Holes in the filter appear as bright spots. Inspect
the element for tears, an oily film, or damage to the
rubber seal. If the filter is damaged, do not use it.
3. Carefully slide the primary filter into the filter body
(
Figure 35 ). Ensure that it is fully seated by pushing on
the outer rim of the filter while installing it.
