Filling the engine cooling system
Depending on your vehicle's equipment
Check that the drain plugs are quite tight.
Initially fill through the filler (2), pouring the
coolant slowly to enable all the air to escape
from the system.
Top up with coolant until flush with the port.
Refit filler cap (2).
Start the engine.
Run the engine for 3 minutes at 1 200 rpm, then
stop it.
Carefully open pressure-vacuum cap (1).
Check the level and top up, if necessary. Put
back filler cap (2).
Run the engine until it reaches its operating
temperature (thermostat open), then stop it.
Let the engine cool down and top up with coolant, if necessary.
Vehicle equipped with air/water independent heater
Bleed air from the heater. To do so, run the heater for 15 to 20 seconds, operate the electric
water circulating pump. Top up with coolant when the heater has stopped.
If the heater trips out, bleed the cooling system once again.
In addition to the dashboard "alert" pictogram (G31), the coolant level in the
expansion chamber is visible through a transparent wall.
If for some vital reason the coolant has to be topped up while the engine is hot,
first of all carefully release the pressure-vacuum cap (1) by 1/4 of a turn to
decompress the system.
Retighten the cap immediately. Then remove the filler cap and top up the cool-
ant.
