(whichever occurs first) carry out the
preceding checks plus the following:
OPERATION 30
COOLING SYSTEM
During manufacture, the engine cooling system is
filled with a high quality antifreeze and water solution.
The antifreeze contains a chemical inhibitor. This
inhibitor increases and extends the protection
offered by conventional antifreezes.
The inhibitor will:
Increase rust prevention.
•
Reduce scale formation.
•
Minimise cylinder wall erosion (pitting).
•
Reduce foaming of the coolant.
•
The chemical inhibitor must be replenished, at
intervals, to maintain the optimum protection level.
This protection is provided by draining and flushing
the system and refilling with a 50% solution of Ambra
Agriflu antifreeze or, where this antifreeze is not
available, with a measured dosage of chemical
inhibitor. See the following text.

Draining and Refilling the Cooling System

WARNING
The cooling system operates under pressure which
is controlled by the radiator pressure cap (1). It is
dangerous to remove the pressure cap while the
system is hot. When cool, use a thick cloth and turn
the cap slowly to the first stop and allow the pressure
to escape before fully removing the cap. Coolant
should be kept off the skin. Adhere to the precautions
outlined on the antifreeze and inhibitor containers,
where used.
IMPORTANT: It is essential that an approved
pressure cap is used. If the cap is mislaid or
damaged, obtain a replacement from your dealer.
