How to Add Coolant to the
Coolant Surge Tank
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If you have not found a problem yet,
check to see if coolant is visible in
the surge tank. If coolant is visible
but the coolant level is not at
between the MIN and MAX lines,
add a 50/50 mixture of clean,
drinkable water 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 on
page 10 15 for more information.
WARNING
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
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 the
cooling system can be
dangerous. Plain water, or some
other liquid such as alcohol, can
boil before the proper coolant
they can mixture will. The vehicle's coolant
warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use a 50/50 mixture of
clean, drinkable water and
DEX-COOL
Notice: In cold weather, water
can freeze and crack the engine,
radiator, heater core and other
parts. Use the recommended
coolant and the proper coolant
mixture.
