The coolant must conform to the
manufacturer’s recommendations. The coolant level should be
close to the "MAX" mark but
s h o u l d n e v e r e x c e e d i t .
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

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 avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
