Hydraulic Clutch; Engine Coolant - Chevrolet 2008 Cobalt Owner's Manual

Hydraulic Clutch

The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives fluid from the brake master
cylinder reservoir.
See Brakes on page 5-31 for more information.

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 extended 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 5-23.

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
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 your warranty. Always use
®
DEX-COOL (silicate-free) coolant in your vehicle.
