If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the
temperature gauge, or lower,
before checking the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
anticlockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.
If you don’t find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
).
Start the engine, and set the
temperature control dial to
maximum heat (climate control to
AUTO at ‘‘
’’). Add coolant
to the radiator up to the base of
the filler neck. If you do not have
the proper coolant mixture
available, you can add plain water.
Remember to have the cooling
system drained and refilled with
the proper mixture as soon as you
can.
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).

Removing the radiator cap
while the engine is hot can
cause the coolant to spray
out, seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
