CHECKING THE COOLANT

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 463).
Note: Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

Maintenance
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -29°F (-34°C) and -35°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.
Adding Coolant
WARNING: Keep your hands and
clothing clear of the cooling fan.
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
WARNING: Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury.

WARNING: Do not add coolant
further than the MAX mark.
WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield.
WARNING: Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician.
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.
Note: Automotive fluids are not
interchangeable.
