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 proper level
(2.5
inches
(6.4
cm) below the
base of the fill neck), 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.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system
is
set
for
the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
