Tank
Pressure
Cap
NOTICE:
The surge tank pressure cap
is
a

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.

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.
