only, not directly into the sub
tank. Also, do not check engine
coolant level at the radiator.
.
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.
.
Check the radiator hoses and
connections, heater hoses and
connections, radiator, water pump,
EGR cooler, and SCR system and
hoses for leakage.
If you do not find a leak or other
problem, carefully add engine coolant
to the reserve tank.
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 sub tank. See

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.
Checking the Power Steering Fluid Level
The fluid level is correct if it is between the
“
MAX
”
and
“
MIN
”
lines on the reserve tank.
If the level is lower that the
“
MIN
”
line, add
fluid up to the
“
MAX
”
line.
The reserve tank is located at the rear of
the engine compartment on the left. When
you have finished checking the fluid level,
securely install the cap and cover.
