(22)= Wheel bearing service:
•Grease type — Clean, inspect, and lubricate
with the proper wheel bearing grease at
designated intervals or when hubs are
removed. SeePart C: Recommended Fluids
and Lubricants on page 397.
•Oil-filled type — Some wheel bearings are
lubricated by axle lubricant. When you
have oil-filled hubs, use lubricant identical
to that used in the axle. Lubricant change
intervals are the same for front and rear
axles. However, you must maintain the proper
oil level between change intervals. See
Front Wheel Bearings with Oil-Filled Hubs
on page 319andPart C: Recommended
Fluids and Lubricants on page 397.
(23)= Check the air intake system installation
to see that gaskets are seated properly and
all hose connections, fasteners, and other
components are tight. Tighten connections
and fasteners or replace parts as required.(24)= Evaporative Control System Service,
if equipped: Check all fuel and vapor lines and
hoses for proper connections and correct routing
(or every 24 months, whichever occurs first).
Replace parts as needed.
(25)= Replace spark plugs. Inspect wires for
damage. Check the wire boot and boot heat
shield fit at spark plugs and coil. Replace parts
as needed.
(26)= Check the fuel tank, fuel cap and fuel lines
for damage which could cause leakage. Inspect
fuel cap for correct sealing ability and any
indications of damage. Check fuel cap gasket
for even filler neck imprint. Replace parts as
needed.
(27)= Check Exhaust Gas Recirculation (EGR)
system as described in the service manual.

Part B: Owner Checks and Services
Listed in this part are owner checks and services
which should be performed at the intervals
specified to help ensure the safety, dependability
and emission control performance of your
vehicle.
For your safety and that of others, any of the
safety-related components that may have been
damaged in an accident should be checked
and any needed repairs made before operating
the vehicle.
At the minimum, these routine checks should be
made every 6 months or 6,000 miles (10 000 km),
whichever occurs first. Whenever repairs are
needed, have them completed before operating
the vehicle.
At Each Fuel Fill
It is important for you or a service station attendant
to perform these underhood checks at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper
oil if necessary. SeeEngine Oil (Caterpillar®
Diesel Engine) on page 268orEngine Oil
(Gasoline Engine) on page 268orEngine Oil
(DURAMAX
®/Isuzu Diesel Engine) on page 272.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant (Gas and DURAMAX®/Isuzu
Engines) on page 284orEngine Coolant
(Caterpillar
®Diesel Engines) on page 287.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer fluid reservoir and add
the proper fluid if necessary. SeeWindshield
Washer Fluid on page 296.
Tire Ination Check
Check tire inflation cold. Make sure the tires are
inflated to the correct pressures. SeeLoading Your
Vehicle on page 238andInation - Tire Pressure
on page 322.
391

Lamps Check
Check panel lighting, warning lights, indicator
lights, and interior lamps. On the outside,
check: license plate lamps, sidemarker lamps,
reflectors or lights on outside mirrors, headlamps,
parking lamps, identification and clearance
lamps, taillamps, brake lamps, turn signals,
backup lamps, and hazard warning flashers.
Have headlamp aim checked at once if beams
seem improperly aimed.
Glass, Mirrors, Lamps and/or
Reectors Condition Check
Look for broken, scratched, dirty, or damaged
glass, mirrors, lamps, or reflectors that could
reduce the view or visibility or cause injury.
Replace, clean or repair promptly.
Door Latches Check
Check that doors close, latch, and lock tightly.
Check for broken, damaged, or missing parts that
might prevent tight latching.
Hood Latches Check
Check that the hood closes firmly. Check for
broken, damaged, loose, or missing parts
that might prevent tight latching. Make sure the
secondary latch (if equipped) keeps the hood
from opening all the way when the primary latch
is released.
Fluid Leaks Check
Check for fuel, coolant, oil, or other fluid leaks by
looking at the surface beneath the vehicle after
it has been parked for awhile.
