1994 CHEVROLET ASTRO PASSENGER recommended oil

Downloaded from www.Manualslib.com manuals search engine Just before you leave the lane, glance quickly over your shoulder to make
sure there isn’t another vehicle in your “blind” spot.
Once you are moving on
the freeway, make certain you allow a reasonable
following distance. Expect to move slightly slower
at night.
When you want
to leave the freeway, move to the proper lane well in
advance. If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you must start when you’re
not fresh
- such as after a day’s work - don’t plan to make too many
miles that first part of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep
it serviced and maintained,
it’s ready to go. If
it needs service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
GM dealerships all across
North America. They’ll be ready and willing to help
if you need it.

Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe, trouble-free trip. Is the tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook along your route?
Should you delay your trip a short time to avoid a major storm system?
Maps: Do you have up-to-date maps?

Downloaded from www.Manualslib.com manuals search engine What to Use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids
and Lubricants” in the Index.
Engine 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” in the Index.
The proper coolant for your vehicle will:
0 Give freezing protection down to -20°F (-29”C), or -34°F (-37°C) in
0 Give boiling protection up to 258°F (125 “C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning gages work as they should.
Canada
and for vehicles with the cold climate option.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze
that meets “GM Specification 6038-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to
“GM
Specification 603%”’ with a complete coolant flush and refill. If you use
this mixture,
you don’t need to add anything else.

Downloaded from www.Manualslib.com manuals search engine Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep their luster. Washing
with water is all that is usually needed. However, you may use
GM Chrome
Polish on chrome or stainless steel trim, if necessary.
Use special care
with aluminum trim. To avoid damaging protective trim,
never use auto or chrome polish, steam or caustic soap to clean aluminum.
A coating of wax, rubbed to high polish, is recommended for all bright
metal parts.
Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar to the painted
surface
of your vehicle. Don’t use strong soaps, chemicals, chrome polish,
abrasive cleaners or abrasive cleaning brushes on them because you could
damage this coating. After rinsing thoroughly, a wax may be applied.
NOTICE:
If you have aluminum wheels, don’t use an automatic vehicle
wash that has hard silicon carbide cleaning brushes. These
brushes can take
off the protective coating.
Weatherstrips
Silicone grease on weatherstrips will make them last longer, seal better, and
not stick or squeak. Apply silicone grease
with a clean cloth at least every
six months. During very cold, damp weather more frequent application may
be required. (See “Recommended Fluids
& Lubricants” in the Index.)
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal repair or replacement,
make sure the body repair shop applies anti-corrosion material to
the parts
repaired or replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents, road oil and tar, tree
sap, bird droppings, chemicals from industrial chimneys, and other foreign
matter can damage your vehicle’s finish
if they remain on painted surfaces.
Use cleaners
that are marked safe for painted surfaces to remove foreign
matter.
