If the expansion tank needs
coolant, you will have to remove
thecap.Beforedoingthat,turn
the ignition switch to ON (II), and
check the temperature gauge.
Remove the expansion tank cap
ONLY if the temperature gauge
pointer has come down to normal
or below, and you do not hear any
bubbling or gurgling noises
coming from the cooling system.
Using gloves or large heavy cloth,
turn the expansion tank cap one-
quarter turn counterclockwise
without pushing down. After the
pressure releases, push down on
the cap, and turn it until it comes
off.
Start the engine, and set the
climate control to FULL AUTO at
90°F (32°C). Add coolant up to
the MAX line on the expansion
tank. 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
expansion tank. If it has gone
down, add coolant to the MAX
mark. Put the expansion tank cap
back on tightly.
Put the expansion tank cap back
on tightly. Run the engine, and
watch the temperature gauge. If it
goes back to the red mark, the
engine needs repair (see
on page ).
