Coolant Level - CITROEN DS3 Handbook

Coolant level

The coolant level should be close
to the "MAX" mark but should never
exceed it.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
The cooling fan may start after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.
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.
Fluid specification
The coolant must conform to the
manufacturer's recommendations.
Screenwash fluid level
Top up the level when necessary.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.
