Radiator Precsure Cap (All Engines)
NOTICE:
Your radiator 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. Be sure the arrows on the cap
line up with the overflow tube on the radiator
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
3800 L36 Engine
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there
is a leak in the system or you hear
an unusual noise. A fluid loss in this system could indicate
a problem. Have the system inspected and repaired.

5.7L LT1 Engine
How To Check Power Steering Fluid
When the engine compartment is cool, 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.
The level should be at the FULL COLD mark.
If
necessary, add only enough fluid to bring the level up
to the mark.
e When the engine compartment is hot, the level
should be at the
H or HOT mark.
e When the engine compartment is cool, the level
should be
at C or FULL COLD mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
damage hoses and seals.
