Changing the coolant
The coolant does not have to be changed.
Coolant specifi cation
The coolant must conform to the manufacturer's recommendations.
Coolant level
The coolant level should be close to the "MA X" 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. On vehicles which are fitted with a par ticle
emission filter, the fan may operate after the vehicle has been switched off, 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.
Power steering fluid level
The power steering fluid level should be close to the "MA X" mark. Unscrew the cap, with the engine cold, to check the level.
To check the level or top up the fluid, immobilise the vehicle and switch of the engine.
