(15) = Check complete exhaust system and
cab areas near the exhaust system for broken,
damaged, missing, or out-of-position parts.
Also inspect for open seams, holes, loose
connections, or other conditions which could
let exhaust fumes seep into the driver
compartment. Needed repairs should be
made at once. To help maintain system
integrity, replace exhaust pipes whenever a
new muffler is put on.
(16) = Adjust valve lash. Incorrect valve clearance
will result in increased engine noise and reduced
engine output.
(17) = With the engine off and below normal
operating temperature, check to see that
the thermostatically controlled engine cooling fan
can be rotated by hand on viscous-operated
drives. Replace as needed.
(18) = Check shields and underhood insulation
for damage or looseness. Adjust or replace
as needed.
(19) = Wheel bearing service:
•
Grease type – Clean, inspect, and lubricate
with the proper wheel bearing grease at
designated intervals or when hubs are
removed. See
Part C: Recommended Fluids
and Lubricants on page 295 .
•
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 232
and Part C: Recommended Fluids
and Lubricants on page 295 .
(20) = 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.
