not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood

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 cooling system in the vehicle is
filled with DEX-COOL engine
coolant mixture. See Recommended
Fluids and Lubricants 0 341 and
Maintenance Schedule 0 331.
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,
