Adding Coolant
If
you need more coolant, add the proper
DEX-COOL@
coolant mixture
at the
surge
tank,
but only when the
engine
is
cool.
Surge
Tank
Pressure
Cap
NOTICE:
Your 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 your 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 preset temperature.
When you replace your thermostat, an ACDelco'
thermostat is recommended.
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 coolant on a hot engine.
When replacing the pressure cap, make sure
it
is tight.
