1993 CHEVROLET LUMINA coolant

Downloaded from www.Manualslib.com manuals search engine 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 coolant recovery
tank.
Turning the radiator pressure
b cap when the engine and
radiator are hot can allow steam
and scalding liquids to blow out
and burn you badly. With the
coolant recovery tank, you
will
almost never have to add coolant at
the radiator. Never turn the
radiator pressure cap-even a
little-when the engine and radiator
are hot.
Add coolant mix at the recovery tank,
but be careful not to spill it.
You can be burned if you
spill coolant on hot engine
parts. Coolant contains ethylene
glycol, and it will burn
if the engine
parts are hot enough. Don’t spill
I coolant on a hot engine. I

Radiator Pressure Cap
214
Your radiator cap is a 15 psi
(105 Wa) pressure-type cap and
must be tightly installed to prevent
coolant loss and possible engine
damage
from overheating. Be su
the arrows on the cap line up wi
the overflow tube on the radiato
filler neck.
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.
Power Steering Fluid
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,
When the engine compartment is cool,
the
level should be at the
H mark.
the level should be at the
C mark.

Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash the pressure cap
and neck.
To help ensure proper operation, we recommend a
pressure test of both the cooling system and the
pressure cap.
Transaxle Service-For manual transaxles, fluid
doesn’t require changing.
For automatic transaxles, change both the fluid
