CONSUMABLES

Use GLACEOL RX (TYPE D) coolant or L255 coolant.

Note: Ready-to-use coolant or antifreeze must be diluted with distilled water in accordance with the guidelines marked on the container.

Engine cooling: Precautions for the repair

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 bonnet, as the radiator fan(s) may start to operate without warning.

Do not open the bleed screw(s) with the engine running.

Only use GLACEOL RX (TYPE D) coolant.

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

The system does not operate using pure water.

 

WARNING Drain with the engine warm.

Flush and refill with the engine cold or warm.

Never flush a hot engine (risk of major thermal shock).

 

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 If the coolant is leaking from the expansion bottle cap, replace the valve.

 

Note: Refer to the vehicle's Maintenance Booklet for information on cooling system service intervals.

For any further information, refer to the workshop repair manual of the vehicle concerned.

When a faulty vehicle arrives, check:

  • the condition and tension of the water pump drive belt,
  • that the fan, the radiator and the radiator grille are not obstructed by an object which may impede the flow of air.

Vehicles in the current range have cooling systems with the following specifications:

  • hermetically-sealed pressurised circuit (expansion bottle valve).
Note: Ready-to-use coolant or antifreeze must be diluted with distilled water in accordance with the guidelines marked on the container.
