Engine Coolant - Chevrolet 2007 Express 2007 Express 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 on page 410.
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 on page 410.
•
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
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 311.
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.
