a little higher. When your engine is warm, the level should be up
to the
HOT mark, or a little higher.

x " The coolant surge tank is located on
the
passenger side at the

engine compartment.
To Check Coolant
A CAUTION:
lbrning the surge tank pressure cap when the engine and
radiator are hot can allow steam and scalding liquids to blow \
out
and burn you badly. Never turn the surge tank pressure
cap -
even a little - when the engine and radiator are hot.
When your engine is cold, the coolant level should be at the COLD mark. or
a little higher.
If this light comes on, it means you're low on engine coolant.

To Add Coolant
If you need more coolant, add the proper mix crt the surge tunk, but only
when the engine
is cool. If the surge tank is empty, see “Engine
Overheating”
in the Index for the proper fill procedure.
A CAUTION:
You can be burned if you spill coolant on hot engine parts.
Coolant contains ethylene glycol, and
it will burn if the engine
parts are hot enough. Don’t spill coolant on
a hot engine.
When replacing the pressure
cap, make sure it is tight.
Radiator Pressure Cap - Gasoline Engine
The radiator pressure
cap
must be tightly
installed
with the
arrows on the cap
lined up with the
overflow tube
on the
radiator filler neck.
U
NOTICE:
Your radiator cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed to prevent coolant
loss and possible
engine damage from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator filler neck.

Surge Tank Pressure Cap - Diesel Engine
The surge tank
pressure cap must
be
tightly installed with
the arrows on the cap
lined up with the top
tube
of the coolant
surge tank.
NOTICE:
Your surge tank pressure cap is a unique 15 psi (105 kPa)
pressure-type cap for use with surge tank cooling systems only.
It must be tightly installed to prevent coolant
loss and possible
engine damage from overheating. Be sure the arrows on the cap
line up with the top tube of the coolant surge tank.
Thermostat
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the flow
of coolant through the
radiator
until the coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
