Warning
An underhood electric fan
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.
Warning
Do not touch heater or
radiator hoses, or other
engine parts. They can be
very hot and can burn you.
Do not run the engine if
there is a leak; all coolant
could leak out. That could
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The engine cooling system in
the vehicle is filled with
DEX-COOL engine coolant
mixture. This coolant needs to
be checked and changed at
appropriate levels. See
Recommended Fluids and
Lubricants 0 433 and
Maintenance Schedule 0 429.
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
