236 Check ing and filling
• Place a thick rag ov er the coolant expansion
tank ¢
page 235, fig . 196 and care fully
twist the cap counter-clockwise ¢ &_.
• Add coolant mixed in the correct ratio
¢ page 234, Coolant.
• Twist the cap on again tightly .
Replacement engine coolant must conform to
exact specifications ¢
page 234, Coolant .
We recommend using on ly coo lant addi-
tive
Gl2++, Gl3 or in an emergency Gl2 +. Do
not use a different additive. In an emergency
use plain water unt il you can get the correct
addit ive 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 antifree ze
and cold water only when the eng ine is co ld.
A lways use
new engine coolant when refi lling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out t hrough the
press ure relief valve in the cap when the en­
gin e becom es hot.
A WARNING
- The coo ling system is under p ress ure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps .
- Tu rn o ff the eng ine a nd a llow i t to cool
down.
- Pr otect your f ace, hands and arms from
escaping f luid and steam by cover ing
the cap with a large, thick rag.
- Tu rn the cap slowly and very ca re fully
in a counte r-clockwise direct ion while
applying light, downwa rd p ress ure on
the top of the cap.
- To avoid being burned, do not spi ll an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can catch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and well
out of the reach of children. -
If you drain the coo lant, it m ust be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coo lant poll utes the environment and
cou ld 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 234 must be re­
stored as soon as possible .
® For the sake of the environment
Drained coolant should not be reused. Al­
ways d ispose of used coolant while observ ­
i ng all environmental regulations .
