Coolingsystem protective liquidl (Anti-freeze)
The preparation and monitoring of coolant in inter-cooled engines is especially important because corrosion, cavitation and freezing can lead to engine damage. Use as coolant a mixture of a cooling system protective liquid (anti-freeze, ethylene glycol based) and tap water.
As cooling system protetctive liquid use a ethylene-glycol based anti-freeze. This will give an adequate protetcion against corrosion, cavitation and frost damage.
In tropical climates, where anti-freeze availability may be limited, use a corrosion inhibitor to protect the engine cooling system. The concentration of the cooling system protective liquid in the coolant should not fall below/exceed the following limits: Cooling system protective liquid (Anti-freeze)
Water
Protection against freezing to
35 vol.%
65 vol. %
-22°C (-8°F)
40 vol.%
60 vol.%
-28°C (-18°F)
45 vol.%
55 vol.%
-35°C (-31°F)
The protective liquid concentration must be maintained under all circumstances. Therefor if coolant must be added always use the same mixture of anti-freeze and tap water.
For example:
ARAL ESSO Mobil Shell TOTAL BP
Antifreeze Extra ESSO Antifreeze Extra Mobil Antifreeze Extra GlycoShell ELF Glacelf MDX BP Antifrost Code No. X2270 A
In tropical climates, where anti-freeze availability may be limited, use a corrosion inhibitor to protect the engine cooling system.
Caution! Cooling system protective liquids must be disposed of in accordance with environmental regulations.
