cause an engine Pire, and you could be burned.
Get any leak fixed before you drive the vehicle.
If there seems to be no leaK, start tne engine again to see
if the fan runs when the engine does. If it doesn’t,, your
vehicle needs service. Turn
off the engine.
How to Add Coolant to the Coolant
Recovery Tank
If you,haven’t found a problem yet, but the coolant level
isn’t at or above
“FULL COLD,” add-a 50/50 mixture of
clean water (preferably distilled) and a proper antifreeze
at the coolant recovery tank. (See “Engine Coolant’’ i\

the Index for more information about the proper coolant
mix.)

Rust or dirt on the wheel,
which it
is fastened, can make the wheel nu
become loose after a time. The wheel could
come
off and cause an accident. When you
change
a wheel, remove any rust or dirt fro1
the places where the wheel attaches to the
vehicle. In an emergency, you can use
a cloth or
a paper towel to
do this; but be sure to use a
scraper or wire brush later, if you need to, to get
all the r---t or dirt off.

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.

thickness. DO not we other visco,sity-oils such ;as SAE
low-40 or SAE 2OW-50.

It’s below freezing outside and most trips are less:
than
10 miles (16 km).
. The engine is -at low .speed most of the time (as in
door
tp door delivery, or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
If -any one of these is true for your vehicle, then you
need-to change
your oil.and filter every 3,000 miles
(5 000 km) or, 3 months - whichever comes first.
If none of them is true, change the oil every 7,500 miles
(12 -500 km) or 12 months - whichever comes first.
Change the filter at the first oil change and
at every
other oil change after that.
Engine Block Heater: An engine block heater can be a
big help if-you have
to park outside in very cold
weather,
-20 * F (-29 C] or .colder. If your vehicle has
this option, see
“Engine Block Heater” in the Index.
What to Do with Used Oil:
Used engine oil contains things that have
caused skin cancer in laboratory animals.
Da
let used oil stay on your skin for very long
Clean your skin and nails with soap and water,

..
Used oil can be a real threat to the environment. If you
change your
own oil, be sure to drain all free-flowing oil
Erom the filter before disposal. Don’t ever dispose of oil
by pouring
it on the ground, into sewers, or into streams
or bodies of water. Instead, recycle it by taking it.to a
place that collects used oil. If you have a problem
properly disposing of your used oil, ask your dealer, a
service station or
a local recycling center for help.

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.
A hot check must €0110~ when fluid is added
