Caution
If the engine coolant surge tank
hose is not carefully lifted out of
the hose retainers on the air
cleaner/filter cover assembly, it
may be damaged and cause
engine coolant to leak. Damage
would not be covered by the
vehicle warranty.
1. Carefully lift the surge tank coolant hose (1) from both
hose retainers (3) and position
the hose to be able to remove
the screws securing the air
cleaner/filter endcap.
2. Loosen the air duct clamp (4) at the air cleaner/filter housing
endcap and move the duct out
of the way.
3. Remove the electrical connector (5) from the sensor.
4. Remove the two screws (2).
5. Turn the air cleaner/filter endcap downward and
disengage the lower endcap
mounting tabs from the lower
retention hinge features. Be
sure to insert the lower endcap
mounting tabs fully into the
housing retention hinge
features before turning the
endcap upward and replacing
the screws.
6. Inspect or replace the air cleaner/filter.
7. Reverse Steps 1–6 to replace the air cleaner/filter endcap. 8. Replace the extractor hood
duct. See above.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when driving.
