1993 BUICK PARK AVENUE engine overheat

2. Push it back in all the way, wait three seconds and
then pull it back out again.
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.
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 DEXRONWIE, 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.
0 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 overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Buick will:
0 Give freezing protection down to -34°F (-37 “C) .
0 Give boiling protection up to 262 F ( 128 ” C) .
0 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.
A CAUTION:
Adding only plain water to your cooling system
can be dangerous. 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 overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and a proper antifreeze.
If you use an improper coolant mix, your
engine :,,I could overheat and be badly damaged. The’: . -
repair cost wouldn’t be covered by your -.. - ’
warranty. Too much water in the mix can !ete;::
and crack the engine, radiator, heater
Core and
other parts.

Radiator Pressure Cap
Your radiator pressure cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly install
to prevent coolant
loss and possible engine
damage from overheating. Be sure the arro
the cap line up with the
ov be on t
radiator filler neck.
Power Steering Fluid
When you replace your radiator pressure cap, an AC@
cap
is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
When
you replace your thermostat, an AC@ thermostat
is recommended.
How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick with a clean rag.
Replace
the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
When the engine compartment is hot, the level
should be at the
“HOT” mark.
0 When the engine compartment is cool, the level
should be at the “FULL COLD” mark.
