Service & Appearance Care
What to Use:
Use a mixture of clean water (preferably distilled) and antifreeze that meets
“GM Specification 6038-M,” which won’t damage aluminum parts. Also use
GM Engine Coolant Supplement (sealer) with
a complete coolant change. If
you use these, you don’t need to add anything else.
I
Adding only plain water to your cooling system can be dangerous.
proper coolant mix will. Your vehicle’s coolant warning system is set
for the proper coolant mix. With plain water or the wrong mix, your
engine could get
too hot but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others could be burned. Use
- Plain water, or some other liquid like alcohol, can boil before the
II a 50/50 mix of clean water and a proper antifreeze.
NOTICE

badly damaged. The repair cost wouldn’t be covered by your warrant\
y
much water
in the mix can freeze and crack the engine, radiator, hea
core and other
part
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when th\
e engine is cold
and follow the steps under “Adding Coolant” for the prope\
r way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.

Service & Appearance Care
To Check Brake Fluid:
You can check the brake fluid without taking off the cap. Just look at the
windows on the brake fluid reservoir. The fluid levels should be above
MIN. If
they aren’t, have your brake system checked to see if there is a leak.
After work is done on the brake hydraulic system, make sure t\
he levels are above
MIN and below the top of each window.
What To Add
When you do need brake fluid, use only DOT-3 brake fluid-such as Delco
Supreme
11 @ (GM Part No. 1052535). Use new brake fluid from a sealed
container only.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together if the vehicle is to have really good
braking. Vehicles we design and test have top-quality GM brake parts in
them, as your vehicle does when
it is new. When you replace parts of your
braking system-for example, when your brake linings wear down and you
have to have new ones put in-be sure you get new genuine GM
replacement parts.
If you don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change, for the\
worse. The braking performance you’ve come
to expect can change in many other ways
if someone puts in the wrong replacement brake parts.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.

Downloaded from www.Manualslib.com manuals search engine Battery
Every new GM vehicle has a Delco Freedom battery. You never have to add
water to one of these. When it’s time for a new battery, we recommend a
Delco Freedom battery. Get one that has the catalog number sho\
wn on the
original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
Batteries have acid that can burn you and gas that can explod\
e. Yo1
can be badly hurt if you aren’t careful. See “Jump Starting” in the
Index for tips on working around a battery without getting hur\
