Engine OiI
If the "LOW OIL" light on '
the instrument panel comes
on, it means .you need to
check your engine oil level
right away. You should
check your engine oil level
regularly; the light
is an
added reminder.
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground. From the front, you'll
see
your oil hpstick to the left
of 'the air cleaner. Turn off
the engine and give the oil a
fe.w minutes.
to drainget
back down-into the
oil pan.
If
you don't, the oil dipstick
might not show the actual
h%l.
To Check Engine Oil: Pull
out the dipstick slightly.
Pinch the ,end of the
dipstiek tube as you remove
the dipstick to wipe the oil
fi-om it. Then,push it' all the
way back
in. No.w, remgve
it without pinching the tube,
keeping the tip lcmer.

Automatic Transmission Fluid
When to Check and Change:
A good time to check your auiomatic 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 Buick,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. Wait
at least
30 minutes before checking the
transmission fluid level
if you have been driving:
0 When outside temperatures are above. 90 F ‘(32 C);
0 At high speed for quite a while. I
In heavy traffic - &specially in hot weathEr.: . .
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180 F to 200 *F (82 C
To check transmission fluid hot: Get the vehicle ‘warmed
up
by driving about 15 miles (24 krn) when outside
temperatures are above
50 F (1 0 C). If it’s colder than
50 F ( 10 C), drive the vehicle in “D” (3rd Gear) until
the engine temperature gage moves and then remains
steady for ten minutes. Then follow the hot check
procedures.
To check transmission fluid cold: A cold check is made
after the vehicle has been sitting for
8 hours or more
with the engine
off and is used only as a reference. Let
the engine run at idle for
5 minutes if outside
temperatures are
50 F (10 C) or more. If ‘it’s colder
than
50 OF (10 * C), you may have to idle the engine
longer.

Introduction
A Word About Maintenance
We at General Motors want to help, you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times’ a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or you
may drive it to work,
to do errands or in many other
ways.
Because
of all the different ways people use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than
you will
find
in the schedules in this part. So please read this part
and note how you drive. If you have any questions
on
how to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners thoose to
have their maintenance work done. Your dealer can be
relied upon to use proper parts and practices.
