Then, without shutting off the engine, follow these
steps:
1. Pull out the dipstick
and wipe it with
a
clean rag or paper
towel.
‘i
2. Push it back in all the way, wait three seconds and
then pull it back out again.
A
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be
in the cross-hatched
area.
4. If the fluid level is where it should be, push the
dipstick back
in all the way.
How to Add Fluid:
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants’’
in the Index.
ProCarManuals.com

If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick. It doesn’t take much fluid, generally less than a
pint. Don’t overfill. We recommend you use only fluid
labeled DEXRONB-IIE, because fluids with that label
are made especially for your automatic transaxle.
Damage caused by fluid other than DEXRONB-IIE is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How
to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheat.ing or if you need to add coolant to your
radiator, see “Engine Overheating”
in the Index.
The proper coolant for your Buick will:
0 Give freezing protection down to -34OF (-37OC) .
0 Give boiling protection up to 262 OF (128 “C) .
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825-M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change. If you use these, you
don’t need to add anything else.
can be aangerous. Plain water, or some other
liquid like alcohol, can boil before the 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 overhe-”
warning. Your engine could catch fire and
yuu or
others could be burned. Use a 50/50 mix of clean
water and a proper antifreeze.

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by
your
warranty. Too much water in the mix can freeze
and crack the enqine, radiator, heater
core and
other parts.

The 3.8 liter engine has the coolant recovery tank
located at the left of
the engine compartment.
To Check Coolant: When your engine is cold, the
coolant
level should be at “COLD” or a little higher.
When your engine is warm, the level should
be up to
“HOT,” or a little higher.

If this light comes on, it means you're low on engine
coolant. this light comes
on, it means you're low on
engine coolant (diesel engine only).
To Add Coolant: If you need more coolant, add the
proper mix at the coolant recovery tank.
A CAUTION:
Turning me raalaror pressure cap when the
--1gine and radiator are hot can allow steam ana
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almos'
never have to add coolant at the radiator. Never

Add coolant mix at the recovery tank, but be careful not
to spill it.
IU can be burned if you spill coolant on hot
gine parts. Coolant contains ethylene glycol,

Thermostat
Engine coolant temperature is controlled by a thermostat

flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat

leak.
If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake
linings. You should add (or remove) brake fluid,

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 Buick 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

GM replacement parts. If
you don’t, your brakes may no
