You MUST stop as soon as it is safe to do so.
Wait a few minutes before switching off the
engine.

coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the
pressure to drop. When the pressure
has dropped, remove the cap and top
up the level.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades.
Specification of the fluid
To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water.
In wintry conditions, the use of an ethyl alcohol
or methanol base fluid is recommended.
