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.
