If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(seeon
page ).
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 tempera-
ture gauge, or lower, before
checking the radiator. 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 (seeon page ).
Start the engine, and set the
interior temperature to maximum
heat (each temperature control
sets to ‘‘ ’’). Add coolant to
the radiator up to the base of the
f iller 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.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down
