Automatic Transaxle Fluid; Engine Coolant - Pontiac 2005 G6 Owner's Manual

Automatic Transaxle Fluid

It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon
as possible.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
•
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•
In hilly or mountainous terrain.
•
When doing frequent trailer towing.
•
Uses such as found in taxi, police or
delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice: Use of automatic transaxle fluid labeled
®
other than DEXRON -III, Approved for the
H-Specification, may damage your vehicle, and the
damages may not be covered by your warranty.
Always use automatic transaxle fluid labeled
®
DEXRON -III, Approved for the H-Specification.

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 5-22.
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.
