IMPORTANT
When working in the engine compartment, take
care as the radiator fan(s) may start up unexpect-
edly (risk of being cut).
To avoid any risk of serious burns when the engine
is hot:
-do not open the expansion bottle cap,
-do not drain the cooling system,
-do not open the bleed screw(s).
WARNING
Before the operation, protect the electrical accesso-
ries to prevent any risk of shor t circuiting and pro-
tect the belts to avoid damaging them.
WARNING
When carr ying out a repair that requires a complete
change, it is essential to flush the circuit with clean
water, blast compressed air through the circuit to
drive out the water, fill and bleed the circuit and
then measure the effective protection.
The cr iteria to be met are:
-protection down to -25˚C ±± ± ±
2 for cold and temper-
ate countries,
-protection down to -40˚C ±± ± ±
2 for "extreme cold"
countries.
WARNING
The coolant helps to keep the engine running prop-
erly (heat exchange).
The system does not operate using pure water.AIR CONDITIONING
