Engine Coolant - Buick Enclave 2008 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 6-11.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the crosshatched area on the
dipstick.
1. Remove the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It does not take much fluid, generally less than
one half of a pint (0.25 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 6-11.
3. After adding fluid, recheck the fluid level as
described under "How to Check Automatic
Transmission Fluid," earlier in this section.
4. When the correct fluid level is obtained, twist & lock
dipstick cap 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 or if you need to add coolant to
the radiator, 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, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the first maintenance
service after each 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.
