1995 Oldsmobile Achieva engine overheat

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir
is
filled with hydraulic clutch fluid.
It isn’t a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct
a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance
Schedule to determine how
often you should check the
fluid level in your clutch
master cylinder reservoir
and for the proper fluid. See
“Owner Checks and
Services” and
“Recommended Fluids and
Lubricants” in the Index.
How to Check
If you can see fluid in the reservoir, the level is
acceptable.
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 Oldsmobile will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F ( 128 O 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 clearz water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 182SM,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. Use
GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill.
If you use
this mixture, you don’t need to add anything else.
I
I NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cast wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.

To Check Coolant
When your engine is cold, the coolant level should be at
the FULL COLD mark,

If this light comes on,
it means you’re low on
engine coolant.
To Add Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
When replacing the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
NOTICE:
Your pressure cap is an 18 psi (124 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.
%%en you replace your surge tank pressure cap, a GM
cap is recommended.
