Engine Coolant - Chevrolet 2009 Express Owner's Manual

CAUTION:
{
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
CAUTION:
{
Heater, fuel operated heater (FOH), radiator
hoses, and other engine parts, can be very hot.
Do not touch them. If you do, you can be burned.
Do not 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.
Notice: Using coolant other than DEX-COOL may
cause premature engine, heater core, radiator
and fuel operated heater (FOH) corrosion. In
addition, the engine coolant may require changing
sooner, at 30,000 miles (50 000 km) or 24 months,
whichever occurs first. Any repairs would not
be covered by your warranty. Always use DEX-COOL
(silicate-free) coolant in your vehicle.

Engine Coolant

The cooling system in the vehicle is filled with
®
DEX-COOL engine coolant. This coolant is designed
to remain in the vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a
problem with engine overheating, see Engine
Overheating on page 5-32.
