Vehicle Care
1. Turn the pressure cap slowly
counterclockwise. If a hiss is heard, wait
for that to stop. A hiss means there is
still some pressure left.
2. Keep turning the cap and remove it.
3. Fill the coolant surge tank with the
proper mixture to 5
–
10 mm (0.2
–
0.4 in)
above the mid-point on the coolant
surge tank.
4. With the coolant surge tank cap off,
start the engine and let it run until the
upper radiator hose starts getting hot.
Watch out for the engine cooling fan. By
this time, the coolant level inside the
coolant surge tank may be lower. If the
level is lower, add more of the proper
mixture to the coolant surge tank until
the level reaches 5
–
10 mm (0.2
–
0.4 in)
above the mid-point on the coolant
surge tank.
5. Replace the cap tightly.
6. Check the level in the surge tank when
the cooling system has cooled down.
If the coolant is not at the proper level,
repeat Steps 1
–
6 and reinstall the
pressure cap. If the coolant still is not at
the proper level when the system cools
down again, see your dealer.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Engine Overheating
The vehicle has an engine coolant
temperature gauge on the instrument
cluster to warn of engine overheating. See
Engine Coolant Temperature Gauge
If the decision is made not to lift the hood
when this warning appears, get service help
right away. Contact your dealer for
additional information.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fans
are running. If the engine is overheating,
both fans should be running. If they are not,
do not continue to run the engine. Have the
vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
