Checking Coolant
The charge air coolant surge tank is
in the engine compartment on the
driver side of the vehicle. See
Engine Compartment Overview 0 37
for location.
The vehicle must be on a level
surface. When the engine is cold,
the coolant level should be at the
indicated mark.
Adding Coolant
If the coolant level in the charge air
coolant surge tank is low, return the
vehicle to your dealer to be checked
for leaks, purged of air and coolant
level adjustment.
Engine Overheating
There is an engine coolant
temperature gauge on the
instrument cluster. See the owner
’ s
manual.
If Steam Is Coming from the
Engine Compartment
{
Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
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.
If No Steam Is Coming from
the Engine Compartment
A Driver Information Center (DIC)
message, along with a low coolant
condition, can indicate a serious
problem.
If there is an engine overheat
warning and the vehicle does not
have a low coolant condition, and
no steam is heard or seen, the
problem may not be too serious.
Sometimes the engine can get a
little too hot when the vehicle:
.
Climbs a long hill on a hot day.
.
Stops after high-speed driving.
.
Idles for long periods in traffic.
