container out of the reach of children. It
is a poison hazard.
@ 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 Lim ited
Warranty.
Adding coolant
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS q A in Working in the engine compart­
ment on pag e 173.
"'Add coolant .
"'Twist the cap on again
tightly.
"'Tighten the cap (D q page 182, fig. 145
again.
Replacement engine coolant must conform to
exact specifications
q page 181, Coolant .
We recommend using only coolant additive
G12++, G13 or in an emergency G12 +. Do
not
use a different additive. In an emergency use
plain water until you can get the correct addi­
tive and can restore the correct ratio. This
should be done as soon as possible.
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
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.
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.
Checking and filling 183
- 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 . Ex cess 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
q page 181 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.
Brake fluid
Have the brake fluid changed by an experi­
enced t echnician.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
afte r a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance. .,.. •
