Engine Coolant - Chevrolet 2003 Blazer 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 clutch
master cylinder reservoir and for the proper fluid. See
Part B: Owner Checks and Services on page 6-26
and Part D: Recommended Fluids and Lubricants on
page 6-33.
How to Check and Add Fluid
The proper fluid should be added if the level does
not reach the bottom of the diaphragm when it's in
place in the reservoir. See the instructions on the
reservoir cap.
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 5-26.
