engine overheat PONTIAC FIREBIRD 1998 Owner's Manual

Radiator Pressure Cap (All Engines)
I 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, a GM 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, a GM thermostat
is
recommended.
Power Steering Fluid
The power steering fluid
reseivoir is locatei toward
the back
of the engine on
the driver’s side.
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.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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.
