MIN and MAX marks when the engine
is cold (when the engine is warm, the
coolant level may exceed slightly the
MAX mark). If the coolant level is too
low, it is necessary to add it.
n For year round, add antifreeze
(specification ASTM 4985) and distilled
water in the ratio specified
(see the
manufacturer´s instructions on the
antifreeze packing).
n All year-round use of antifreeze
protects the cooling and heating system
against corrosion and sediments. For
that reason do not reduce the
concentration of the antifreeze by
adding water even during the warm
season of the year (always add it in the
ratio with antifreeze).
n Take care not to spill the antifreeze on
the body paint.
n Before the winter season comes,
check the antifreeze in the cooling
system for condition and concentration.
n Before the summer season comes
and anytime when the face body area
has been polluted, clean the radiator
with compressed air or stream of hot
water from the engine side.
Check the expansion tank cap.
n Have the coolant changed at the
authorized service station.
n Do not open the cap of coolant
reservoir when the engine is hot -
danger of scalding!
n Never run the engine with the
thermostat removed.
n The expansion reservoir pre-
vents the bleeding of the cooling
and heating circuit. Remember to
check the coolant level.
n When the engine overheats or
the coolant leaks, have it correc-
ted by the authorized service sta-
tion.

Checking and adding the coolant
n The label saying which kind of cool-
ant has been filled, is situated on the
expansion tank or by the expansion
tank.The cooling system has been filled
with the fluid based on ethylene-glycol.
The mentioned coolants can be mixed
with coolants based on ethylene-glu-
col (C type).
n
Check the coolant level at regular
terms.
n The coolant level must be between
