Engine Coolant
qInspecting Coolant Level
WARNING
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS
HOT.
Electrical Fan and Engine
Inspection:
Working near the electrical cooling
fan when it is running is dangerous.
You could be hit by the fan and
seriously injured. Turn off the ignition
switch and make sure the fan is not
running before attempting to work
near the electrical cooling fan.
Cooling System Cap:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove the cooling
system cap when the engine and
radiator are hot.
NOTE
Once the engine coolant exceeds a
preset temperature, an electrical cooling
fan turns on. It will continue running
for about 10 minutes after the ignition
switch is turned to off.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year ―at the beginning of the
winter season ―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks
on the coolant reservoir when the engine
is cool.
If it's at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
