Maintenance
Maintain coolant concentration within
ENGINE COOLING FAN
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
WARNING
Keep your hands and clothing clear
of the engine cooling fan.
Under certain conditions, the engine
cooling fan may continue to run for several
minutes after you switch your vehicle off.
Adding Coolant
WARNING
ENGINE COOLANT CHECK
Never remove the coolant reservoir
cap when the engine is running or
hot.
WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
Note: Automotive fluids are not
liquids released from a hot cooling
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you.
Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See Capacities and
Specifications (page 275). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
Do not add coolant further than the
MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 409).
Note: Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Capacities and Specifications (page 275).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
