Cooling

IMPORTANT To avoid any risk of damaging the systems, follow the instructions regarding safety and cleanliness and operation recommendations before carrying out the repair.

 

IMPORTANT When working in the engine compartment, take care as the radiator fan(s) may start up unexpectedly (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 accessories to prevent any risk of short circuiting and protect the belts to avoid damaging them.

 

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 -25ºC +- 2 for cold and temperate countries,
  • protection down to -40ºC +- 2 for "extreme cold" countries.

 

WARNING The coolant helps to keep the engine running properly (heat exchange).

The system does not operate using pure water.
