Coolant recommendations
NOTE:
It is imperative that vehicles fitted
with an air conditioning system
have a coolant concentration of
the recommended strength at all
times. The use of the air condition-
ing system when the cooling sys-
tem is filled with water only will
result in the heater matrix freezing
and subsequently bursting.
!
Only ethylene glycol based coolant
with a corrosion inhibitor suited to
aluminium alloy engine components
should be used in the cooling system.
No further additives or inhibitors
should be used. The coolant specific
gravity should be checked as pre-
scribed in the maintenance schedule
to ensure adequate frost and corro-
sion protection. In addition, the en-
gine coolant must be replaced at the
specified interval since the corrosion
inhibitor properties deteriorate with
time.
WARNING:
Do not remove the radiator cap
when the engine is hot, since the
system is pressurized and coolant
may be ejected from the radiator
resulting in scalding.
It is important to note that whilst an
increase in the concentration of anti
freeze gives an increase in the level
of frost protection, a solution which is
in excess of 65% anti freeze will
result in reduced frost protection and
engine overheating. Therefore the
recommended concentration of 50%
should not be exceeded for general
use.
The use of methanol based anti freeze
compounds may result in engine over-
heating and will invalidate the vehicle
warranty.
