transmission oil CHEVROLET ASTRO PASSENGER 1994 1.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine How long should you keep the coolant heater plugged in? The answer
depends on the weather, the kind
of oil you have, and some other things.
Instead of trying to list everything here, we ask that you contact a
GM
dealer in the area where you’ll be parking your vehicle. The dealer can give
you the best advice for
that particular area.
Automatic Transmission
There are several
different positions for
your shift lever.
P (Park) - This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured.
and both your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and shift to
5. Release the regular brakes.
“P” (Park).
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Thin.gs that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. Each of these
is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically
to see that all hitch nuts and bolts are tight.
Trailer Light Wiring
See “Trailer Wiring Harness” in the Index.

Downloaded from www.Manualslib.com manuals search engine If you have the 4.3L engine (VIN Code W) with the square air cleaner, you
can change the air cleaner filter without removing the engine cover. Just lift
the hood, unsnap both clips and remove
the top. After changing the filter,
snap both clips to secure
the air cleaner. Be sure air cleaner lid is correctly
positioned to seal out dust and contaminants that are harmful
to your engine.
Refer to the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services”
in the Index.
NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt can easily get into your engine, which
will damage
it. Always have the air cleaner in place when you’re drivin\
g.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at a GM dealership Service Department.
If you do it yourself, be sure to follow all the instructions here,
or you could
get a false reading on the dipstick.
