Engine Coolant - Pontiac 2005 Grand Prix Owner's Manual

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See Recommended Fluids
and Lubricants on page 6-12.
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. Pull out 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 pint (0.5 L). Do not overfill.
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.
3. After adding fluid, recheck the fluid level as
described under "How to Check," earlier in
this section.
4. When the correct fluid level is obtained, push the
dipstick back in all the way.

Engine Coolant

The cooling system in the vehicle is filled with
®
DEX-COOL engine coolant. This coolant is designed
to remain in the vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first, if only
®
DEX-COOL extended life coolant is added.
The following explains the cooling system and how to
add coolant when it is low. If there is a problem
with engine overheating or if coolant needs to be added
to the radiator, see Engine Overheating on page 5-27.
A 50/50 mixture of clean, drinkable water and
®
DEX-COOL engine 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.
