Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM has
derated the engine to limit the likelihood of
permanent damage to the after-treatment
system. If this condition is not corrected and a
dealer service is not performed, extensive
exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have
your vehicle serviced by an authorized dealer.
NOTE:Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by
0 miles remaining will prevent the diesel exhaust
filter from performing it's cleaning routine. This will
shortly result in a Malfunction Indicator Light (MIL)
and reduced engine power. Only an authorized
dealer will be able to correct this condition.

Checking Coolant Level — 5.7L Engines
With the engine off and cold, the level of the engine
coolant should be between the ADD and SAFE
range on the dipstick.
To check the coolant level:

1. Open the coolant reservoir.

2. Lift and remove the plastic dipstick from the
reservoir neck.

Coolant Reservoir Dipstick

3. Check the coolant level on the dipstick.
The radiator normally remains completely full, so
there is no need to remove the radiator cap unless
checking for engine coolant (antifreeze) freeze
point or replacing engine coolant. Advise your
service attendant of this. As long as the engine
operating temperature is satisfactory, the coolant
bottle need only be checked once a month. When additional engine coolant is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo
-
meters of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from rain,
snow, or high humidity accumulating on the
radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks, the
vehicle may be safely driven. The vapor will soon
dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro -
sion protection of your engine which contains
aluminum components.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces -
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
CHARGE AIR COOLER — INTER-COOLER
(D
IESEL ENGINE)
The charge air cooler is positioned in front of the
radiator and the air conditioner condenser. Air
enters the engine through the air cleaner and
passes through the turbocharger, where it is
pressurized. This pressurized air rapidly reaches
high temperature. The air is then directed through
a hose to the charge air cooler and through
another hose to the intake manifold of the engine.
This cooling process enables more efficient
burning of fuel resulting in fewer emissions.
