Engine Cooling
WARNING: For reasons of safety, care
should be taken to ensure that the
ignition is switched off when working in
the vicinity of the fan as an increase in
coolant temperature may cause the fan
to operate without warning.
The major cooling system components comprise
an aluminum radiator core with plastic end tanks,
water circulation pump, thermostat expansion
tank and electrically driven cooling fan.
The wax type thermostat ensures rapid engine
warm up by restricting coolant flow at lower
operating temperatures, it also assists in
maintaining engine operating temperatures
between pre-determined limits.
The cooling fan is mounted within a shroud
behind the radiator.
Antifreeze
WARNING: Antifreeze contains
monoethylene glycol and other
constituents which are toxic if taken
internally and can be absorbed into the
skin after prolonged contact.
Antifreeze content should be checked through
the neck of the expansion tank with a
hydrometer. The specific gravity (sg) of correctly
balanced fluid is 1,061 (sg) at 15°C, which
indicates an antifreeze concentration of 50%. If
the concentration falls below 50% there is
insufficient low temperature protection and the
corrosion resistance will be inadequate. In such
cases the concentration must be brought back to
specification.
Changing coolant
WARNING: When draining the engine
coolant or changing any cooling system
components. It is imperative that no
coolant comes into contact with the
camshaft or auxiliary drive belts. If
necessary the drive belts should be
removed. Contamination of the drive belt
can result in drive belt failure.
Engine coolant is formulated to last for the
lifetime of the vehicle and does not require
replacement at regular intervals. If however the
coolant is lost or topping up is required the
system should be refilled using L405F antifreeze
to the correct proportion (50% antifreeze).
