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
Prepare for the flow of fluid, and protect the sur-
rounding components.
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.
