Engine Coolant - Chevrolet 2006 Express Van Owner's Manual

How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Fluids and Lubricants (Gasoline Engine) on page 6-13.
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 does not take much fluid, generally less than
one pint (0.5 L). Do not overfill.
Notice: Use of the incorrect automatic transmission
fluid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants (Gasoline
Engine) on page 6-13.
•
After adding fluid, recheck the fluid level as
described under "How to Check Automatic
Transmission Fluid," earlier in this section.
•
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 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 5-25.
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, radiator and
fuel operated heater (FOH) 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.
