LOW
COOLANT
If the LOW COOLANT light r-
-
comes on and stays on, it
means you’re low on
engine coolant.
See
Low Coolant Warning Light on page 3-30.
Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture
at the surge tank, but only when the
engine is cool.
If the surge tank is empty, a special fill
procedure is necessary. See Engine Overheating
on page
5-26 and “How to Add Coolant to the Coolant
Surge Tank under
Cooling System on page 5-29
for instructions. 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
hand-tight.
Engine Overheating
You will find a coolant temperature gage and a low
coolant warning light on your vehicle’s instrument panel.
See
Engine Coolant Temperature Gage on page 3-30
and Low Coolant Warning Light on page 3-30.

Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them. If you
do, you can be burned.
Don't run the engine
if there is a leak. If you
run
the engine, it could lose all coolant. That
could cause an engine fire, and you could be
burned. Get any leak fixed before you drive
the
vehicle.
The coolant level should
be at or above the FULL
COLD mark. If it isn't, you may have a leak at the
pressure cap or in the radiator hoses, heater hoses,
radiator, water pump or somewhere else in the cooling
system.
If there seems to be no leak, with the engine on, check
to see
if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running.
If they aren't, your vehicle needs service.
Notice: Engine damage from running your engine
without coolant
isn't covered by your warranty.
