Surge Tank Pressure Cap - Pontiac 1998 Sunfire Owner's Manual

Turning the surge tank pressure cap when the
engine and radiator are hot can allow
steam
and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
--
even a
little
--
when the engine and radiator are hot.
When your engine is
cold, the coolant level should be at
the FULL COLD mark.
If the light comes on, it
means you're
low on
engine
coolant.
See "Low Coolant Light" in
the Index.

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.

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.
