Coolant level

~1min read

The level of this fluid must be close to the "MAXI" mark, never above it.

When the engine is hot, the temperature of this fluid is regulated by the cooling fan.

The fan may run with the ignition switched off.

In addition, the cooling system is under pressure, so wait at least one hour after switching off the engine before carrying out any work.

To avoid any risk of burns, unscrew the cap two turns to release the pressure. Once the pressure has dropped, remove the cap and top up the level.
