Maintenance and care
177
After any coolant has been added,
check the coolant concentration
(see
Checking engine coolant
section). If the concentration is not
50/50 (protection to -34°F /-36°C),
drain some coolant and adjust the
concentration. It may take several
drains and additions to obtain a
50/50 coolant concentration.
Whenever coolant has been added,
the coolant level in the coolant
reservoir should be checked the
next few times you drive the
vehicle. If necessary, add enough
50/50 concentration of engine
coolant and distilled water to bring
the liquid level to the proper level.
If you have to add more than
1.0 liter (1.0 quart) of engine
coolant per month, have your
dealer check the engine cooling
system. Your cooling system may
have a leak. Operating an engine
with a low level of coolant can
result in engine overheating and
possible engine damage.
Changing engine coolant
Change your engine coolant
according to the appropriate
schedule listed in the “Scheduled
Maintenance Guide“. It is important
that the engine coolant be changed
at the specified intervals. The
corrosion protection of engine
coolant is depleted with time and
usage. Use of engine coolant with
depleted corrosion protection may
result in damage to the coolant
system. Color, specific gravity and
freeze point of the coolant are not
indicators of depletion.
To find out how much fluid your
vehicle’s cooling system can hold,
refer to the
Refill capacities
in the
Capacities and Specifications
chapter. Fill your coolant reservoir
following the directions given in
the
Adding engine coolant
section.
Coolant usage in severe winter
climate
If you drive in extremely cold
climates less than -34°F (-36°C), it
may be necessary to increase the
coolant concentration above 50 %.
Refer to the chart on the coolant
container to ensure the coolant
concentration in your vehicle will
provide adequate freeze protection.
Never increase the engine
coolant concentration above
60 %
(protection to -60°F). At a
level over 60 %, your engine could
overheat and become damaged.
Coolant usage in hot climate
If you drive in hot climates, it is still
necessary to maintain the coolant
concentration at 50/50 coolant and
water.
Do not allow the
concentration to fall below
40 % coolant.
At a concentration
less than 40 %, the corrosion
protection to your engine and
cooling components may be
compromised and permanent
damage may result.
