Cooling System; Engine Coolant - Cadillac 2013 ATS Owner's Manual

Cooling System

The cooling system allows the
engine to maintain the correct
working temperature.
1. Engine Coolant Surge Tank and
Pressure Cap
2. Engine Cooling Fan (Out
of View)
WARNING
An electric engine cooling fan
under the bonnet can start up
even when the engine is not
running and can cause injury.
Keep hands, clothing, and tools
away from any underbonnet
electric fan.
WARNING
Heater and 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.
Vehicle Care
Notice: Using coolant other than
®
DEX-COOL can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the first maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs first. Any
repairs would not be covered by
the vehicle warranty. Always use
®
(silicate-free) coolant
DEX-COOL
in the vehicle.
