Surge Tank Pressure Cap - Chevrolet 1997 Cavalier Owner's Manual

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.
~~
A
CAUTION:
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.
Surge Tank Pressure Cap
NOTICE:
Your surge tank 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 AC@ thermostat
is recommended.
