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 pressurised 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.
