Drain Fuel Filter and Check Fuel Lines/Hoses
1. See Figure 5-8. Place a shop rag beneath fuel fil-
ter (A) to catch water or fuel drips.
Figure 5-8. Drain Fuel Filter (2.5L Engine)
2. Turn fuel filter counterclockwise to remove from fil-
ter adapter.
3. Install new fuel filter by hand until gasket just con-
tacts filter adapter. Tighten fuel filter an additional
three-quarters to one full turn.
NOTE: Dispose of used filter at an authorized collection
center.
4. Inspect fuel filter and fuel lines/hoses for leaks.
Tighten filter, fittings, and hose clamps if neces-
sary.
5. Inspect fuel hoses for nicks, cuts, tears, or general
deterioration. Replace as necessary.
Check Coolant Level and Hoses
NOTE: On 2.5L models, remove ten screws to release
louvered air discharge panel on left side of enclosure.
1. See Figure 5-9. Verify coolant level is between
HOT and COLD marks on overflow reservoir (B).
Coolant expands when hot, so coolant level may
be higher than HOT mark. Do not add coolant
higher than HOT mark.
2. If coolant level is below COLD mark, remove fill
cap from overflow reservoir and add coolant. See
Drain/Flush Coolant System.
3. Inspect coolant hoses (A) for leaks. Tighten hose
clamps, if necessary.
4. Inspect hoses for nicks, cuts, tears, or general
deterioration. Replace as necessary.
NOTE: On 2.5L models, install louvered air discharge
panel. Alternately tighten ten screws to 90 in-lbs (10 Nm)
using a crosswise pattern.

Check Radiator for Clogging
Direct flashlight beam through openings in fan guard to
inspect radiator fins. Inspect for debris, accumulations of
dirt, or other deposits. If necessary, clean as follows:
1. On right side of enclosure, loosen two clamps at
each end of turbocharger exhaust outlet pipe.
Remove pipe, clamps, and rubber couplings from
engine.
2. Remove four screws with nylon washers to release
fan guard from radiator shroud.
3. On left side of enclosure, loosen two clamps at
each end of air intake pipe. Remove pipe, clamps,
and rubber couplings from engine.
4. Remove coolant hoses from holding clamps.
5. Remove four screws with nylon washers to release
fan guard from radiator shroud.
6. Carefully remove any debris from radiator fins. Use
warm soapy water and a soft bristled brush to
remove dirt and other deposits, if necessary.
7. On left side of enclosure, install four screws with
nylon washers to fasten fan guard to radiator
shroud.
8. Install coolant hoses into holding clamps.
9. Install clamps and rubber couplings onto each end
of air intake pipe. Install pipe to air heater and radi-
ator shroud. Tighten clamps.
10. On right side of enclosure, install four screws with
nylon washers to fasten fan guard to radiator
shroud.
11. Install clamps and rubber couplings onto each end
of turbocharger exhaust outlet pipe. Install pipe to
