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 en
gine 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 a v o i d a ny 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, tocheck the level. To check the level or top up the
fluid on vehicle fitted with headlamp
washers
, immobilise the vehicle and switch of the engine.
