Engine Coolant; How To Add Fluid - Chevrolet Express 2004 Owner's Manual

How to Add Fluid

Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Fluids and Lubricants on page 6-14.
Using a funnel, add fluid down the transmission dipstick
tube only after checking the transmission fluid while it
is hot. (A cold check is used only as a reference.) If the
fluid level is low, add only enough of the proper fluid
to bring the level up to the HOT area for a hot check. It
doesn't take much fluid, generally less than one pint
(0.5 L). Don't overfill.
Notice: We recommend you use only fluid labeled
®
DEXRON -III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON
not covered by your new vehicle warranty.
•
After adding fluid, recheck the fluid level as
described under "How to Check."
•
When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.

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.
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 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.
