A WARNING ,~
- The cooling system is under pressure. Do
notopenthecapofthecoolantexpan­
sion tank when the engine is hot . You
risk being scalded .
- The coolant additive, and therefore the coolant itself, is hazardous to health.
Keep the coolant additive in the original
container out of the reach of children. It
is a poison hazard.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ &. in Working in the engine compart­
ment on page 169.
.. Add coolant .
.. Twist the cap on again
tightly .
.. Tighten the cap (D ¢ page 176, fig . 144
again.
Replacement engine coolan t must conform to
exact specifications ¢
page 175, Coolant . If
the coolant additive G12+ + is not available in
an emergency, you must not add any other ad­
ditive. In this case, use only water and restore
the correct mix ratio with the specified cool­
ant additive as soon as possible.
Always use
new engine coolant when refilling .
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot .
With a major loss of coolant, you should add
the coolant only when the engine has
cooled.
In this way you prevent engine damage .
Checking and filling 177
A WARNING
-The cooling system is under pressure and
can get very hot . Reduce the risk of
scalding from hot coolant by following
these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire .
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
Q) Note
-Coolant pollutes the environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres ­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze ¢
page 175 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­
ing all environmental regulations.
