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. This can operate with the ignition off.
For vehicles fitted with a particle emissions filter, the cooling fan may continue to run after stopping the vehicle, even if the engine is cold.
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.
Changing the coolant
The coolant does not have to be changed.
Fluid specification
The coolant must conform to the manufacturer's recommendations.
