The coolant level should be at or slightly above the
FULL COLD/FROID line on the side of the coolant
surge tank. 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.

CAUTION:

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.

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.

NOTICE:

When adding coolant, it is important that you use
only DEX

COOL

(silicate

free) coolant.

If coolant other than DEX

COOL is added to the

system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner

30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX

COOL

is not

covered by your new vehicle warranty.
