WARNING
Removing engine
coolant reservoir cap
Never attempt to
remove the engine
coolant reservoir cap while the
engine is operating or hot. Doing so
might lead to cooling system dam-
age and could result in serious per-
sonal injury from escaping hot
coolant or steam.
1. Turn the vehicle off and wait until
it cools down.
2. Use extreme care when removing
the engine coolant reservoir cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop.
3. Step back while the pressure is
released from the cooling system.
4. When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning coun-
terclockwise to remove it.
WARNING
Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is controlled by
coolant temperature, refrigerant
pressure and vehicle speed. It may
sometimes operate even when the
vehicle is not running.
5. Check the condition and connec-
tions of all cooling system hoses
and heater hoses.
6. Replace any swollen or deterio-
rated hoses.
7. Check the coolant level. The cool-
ant level should be filled between
MAX and MIN marks on the side of
the coolant reservoir when the
engine room is cool.
