Engine Coolant; When To Check And What To Use; How To Check And Add Fluid - Pontiac 2004 Sunfire Owner's Manual

When to Check and What to Use

Refer to the Maintenance Schedule to determine how
often you should check the fluid level in your master
cylinder reservoir and for the proper fluid. See
Part B: Owner Checks and Services on page 6-18
and Part D: Recommended Fluids and Lubricants on
page 6-26.

How to Check and Add Fluid

You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, take
the cap off. If the fluid reaches the step inside the
5-20
reservoir, the fluid level is correct. The reservoir is
located near the back of the engine compartment on the
driver's side of the vehicle. See Engine Compartment
Overview on page 5-12 for more information on location.

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 5 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 5-24.
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.
