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 recom-
mended 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.
Diesel engine
!
WARNING:
Do not remove the radiator cap when
the engine is hot, since the system
is pressurised and coolant may be
ejected from the radiator resulting
in scalding.

Coolant recommended
Only ethylene glycol based coolant
with a corrosion inhibitor suited to alu-
minium 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 prescribed in
the maintenance schedule to ensure
adequate frost and corrosion protec-
tion. In addition, the engine coolant
must be replaced at the specified in-
terval since the corrosion inhibitor prop-
erties deteriorate with time.
Petrol engine
NOTE:
It is imperative that vehicles fitted
with an air conditioning system have
a coolant concentration of the rec-
ommended strength at all times.
The use of the air conditioning sys-
tem when the cooling system is
filled with water only will result in
the heater matrix freezing and sub-
sequently bursting.
