Surge Tank Pressure Cap
NOTICE:
The surge tank pressure cap is a
15
psi
(105
kPa)
pressure-type cap and must be tightly installed to
prevent coolant
loss
and possible engine damage
from overheating.
When you replace the surge tank 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 pre-set temperature.
When you replace the thermostat, a GM thermostat
is recommended.
Power Steering Fluid
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.
