351 Operation
Engine compartment
Coolant level
The engine coolant is a mixture of water
and anticorrosion / antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
1Cap
2Coolant expansion tank
3Indicator wall
4Coolant level

Using a rag, turn cap 1 slowly approx-
imately one half turn counterclockwise
to release any excess pressure.

Continue turning cap 1 counterclock-
wise and remove it.
Coolant level 4 is correct if the level:

for cold coolant: reaches the top of
indicator wall 3 visible through the
filling opening


for warm coolant: is approximately
0.6 in (1.5 cm) higher

Add coolant as required.

Replace and tighten cap 1.
For more information on coolant, see the
“Technical data” section (
page 525).
Warning!
G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.


Using a rag, slowly open the cap approx-
imately
1/2 turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.
