Engine Coolant - Saturn 2007 Sky Owner's Manual

Engine Coolant

The cooling system in your vehicle is filled with
®
DEX-COOL engine coolant. This coolant is
designed to remain in your vehicle for five years
or 150,000 miles (240 000 km), whichever
occurs first, if you add only DEX-COOL
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, see Engine
Overheating on page 258.
A 50/50 mixture of clean, drinkable water and
®
DEX-COOL coolant will:
•
Give freezing protection down to 34°F ( 37°C).
•
Give boiling protection up to 265°F (129°C).
•
Protect against rust and corrosion.
•
Help keep the proper engine temperature.
•
Let the warning lights and gages work as they
should.
Notice: Using coolant other than DEX-COOL
may cause premature engine, heater core,
®
extended
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 your warranty. Always use
DEX-COOL
vehicle.
