Engine coolant
Engine coolant
The high-pressure cooling system
has a reservoir filled with year
round antifreeze coolant. The reser
-
voir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before travelling to a colder cli
-
mate.
CAUTION
䳜 When the engine overheats from
low engine coolant, suddenly add
-
ing engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
䳜 Do not drive with no engine cool
-
ant. It may cause water pump
failure and engine seizure, etc.
Checking the coolant level
CAUTION
Removing radiator
cap
Never attempt to
remove the radia
-
tor cap whilst the
engine is operating or hot. Doing so
might lead to cooling system and
engine damage. Also, hot coolant or
steam could cause serious personal
injury.
Turn the engine off and wait until it
cools down. Use extreme care when
removing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back whilst the pressure
is released from the cooling system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and
continue turning counterclockwise
to remove it.
Even if the engine is not operating,
do not remove the radiator cap or
the drain plug whilst the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.
WARNING
The electric motor
(cooling fan) is con
-
trolled by engine
coolant tempera
-
ture, refrigerant
pressure and vehicle speed. It may
sometimes operate even when the
engine is not running. Use extreme
caution when working near the
blades of the cooling fan so that you
are not injured by a rotating fan
blades. As the engine coolant tem
-
perature decreases, the electric
motor will automatically shut off.
This is a normal condition.
