Coolant Level - CITROËN DS 5 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 / headlamp
wash level
To check the level or top up the fluid on vehicle
fitted with headlamp washers, immobilise the
vehicle and switch of the engine.
F Before opening the bonnet, ensure that the
engine has completely stopped.
F Open the screenwash reservoir filler cap.
F Take and pinch the level gauge to block its
breather.
F Remove the gauge completely from
the reservoir to read the level in the
transparent section.
F Top up if necessary.
F Refit the filler cap to the reservoir and
close the bonnet.
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.
