How To Add Coolant To The Coolant Surge Tank - Chevrolet 1998 Cavalier Owner's Manual

If there seems to be no leak, with the engine
on,
check to
see if the electric engine cooling fan is running. If the
engine is overheating, the fan should be running. If it
isn't, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, but the coolant level
isn't at the FULL COLD mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure cap, is
cool before you do it. (See "Engine Coolant" in the
Index for more information.)
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
--
even a little
--
they
can come out at high speed. Never turn the cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge tank pressure
cap to cool if you ever have to turn the
pressure cap.
