sewers, streams, or bodies of water.
Have the coolant changed by an
authorised service centre, familiar
with legal requirements regarding
used coolant disposal. This will help
protect the environment and your
health.

Checking Coolant

The coolant surge tank is in the
engine compartment on the passenger
side of the vehicle. See Engine
Compartment Overview 0 269.
The vehicle must be on a level surface
when checking the coolant level.
Check to see if coolant is visible in the
coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible but
the coolant level is not at or above the
full cold mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
coolant at the coolant surge tank, but
be sure the cooling system is cool
before this is done.
The coolant level should be at or
above the full cold mark. If it is not,
there may be a leak in the cooling
system.
How to Add Coolant to the
Coolant Surge Tank for Petrol
Engines
Warning
Spilling coolant on hot engine parts
can burn you. Coolant contains
ethylene glycol and it will burn if
the engine parts are hot enough.
Warning
Plain water, or other liquids such as
alcohol, may boil before the proper
coolant mixture does. With plain
water or the wrong mixture, the
engine could get too hot but there
would not be an overheat warning.
The engine could catch fire and you
or others could be burned.
Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure cap,
even a little, can cause them to jet
out at high speed and you could be
burned. Never turn the cap when
the cooling system, including the
pressure cap itself, is hot. Wait for
the cooling system and pressure
cap to cool.
