IMPORTANT
The circuits are designed to be pressurised, so be
careful at high temperatures (risk of serious burns).
Do not remove the cap from the expansion bottle
while the engine is hot.
Take care when carrying out a repair under the bon-
net, as the radiator fan(s) may start to operate with-
out warning.
Do not open the bleed screw(s) with the engine run-
ning.
WARNING
When carrying 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 criteria 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
Prepare for the flow of fluid, and protect the sur-
rounding components.
