NOTE:
RISK OF DAMAGE
Injectors contaminated with coolant.
Damage to and failure of injectors that were coated with coolant for an extended period.
Injectors contaminated with coolant.
Damage to and failure of injectors that were coated with coolant for an extended period.
- Covering injectors with suitable auxiliary materials before testing or topping up the coolant is mandatory.
- Covering injectors with suitable auxiliary materials before working on the cooling system in the area of the injectors is mandatory.
- If necessary, draw off all of the coolant from the coolant expansion tank.
- Always clean injectors or injector shafts contaminated with coolant (e.g. with compressed air).
- Check the connections, hose clamps and hoses for coolant residues and damage such as e.g. cracks.
- Check coolant composition in all coolant expansion tanks.
CONSUMABLE SPECIFICATION
| Technically suitable antifreeze and anticorrosion agents |
Check
- Check the coolant level in both coolant expansion tanks.
The fill level in the coolant expansion tank must be between the minimum and maximum mark.
- Inform customer in event of incorrect fluid level and, if necessary, troubleshoot (charged separately).
Result
» Coolant level below the minimum mark.
Coolant level above the maximum mark.
Measure
- Adjust fill level in the coolant expansion tank to the desired fill level.
The according amount of coolant must be supplemented or drawn off.
