.
Make sure the fan belts are
not broken, or off the
pulleys, and that the fan
turns when the engine is
started. Make sure the fan
blade and pulleys are not
broken.
.
Diesel engine only, check
the radiator hoses and
connections, heater hoses
and connections, radiator,
water pump, EGR cooler,
and SCR system and hoses
for leakage.
.
Gasoline engine only, if the
engine coolant level in the
reserve tank is low, look for
leaks at the radiator hoses
and connections, heater
hoses and connections,
radiator, and water pump.
If the engine coolant level in
the reserve tank is at the
correct level but there is still
an indication on the
instrument panel of an
overheat condition:
You must let the engine
cool first. You may then add
engine coolant directly to
the radiator. See "Adding
Engine Coolant" under
5. Inspect to see if there is any
dirt, etc. attached to the front
surface of the radiator. Also,
inspect to see if there is
anything blocking the core.
If there is anything attached,
clean and remove it.
6. After the inspection, regardless
of the vehicle condition, please
contact the nearest dealer.
Once the engine coolant
temperature gauge no longer
signals an overheat condition, you
can resume driving at a reduced
speed. Return to normal driving
after about 10 minutes if the gauge
pointer does not again show an
overheat condition.
When tap water only has been used
for engine coolant in an emergency,
change the engine coolant as soon
as possible.
Engine damage may be caused if
an overheating engine is suddenly
refilled with water. Instead, refill
slowly.
Power Steering Fluid
The power steering fluid level must
be checked and it must be changed
according to the Maintenance
Schedule. See
.
When replenishing power steering
fluid or flushing the power steering
system, always use ATF
(Dexron
®
-VI). Failure to use the
proper fluid may damage the power
steering system seals and hoses,
leading to fluid leakage.
