Precondition 

WARNING: Hot surfaces  .
Risk of burning! 
  • Perform all work only on components that have cooled down.
WARNING: Hot fluids  .
Risk of scalding! 
  • Conduct all work in the vehicle wearing appropriate personal protective equipment only.
CAUTION: Materials harmful to health  .
Contact with fluids harmful to health! 
  • Note and follow safety instructions on containers.
  • Conduct all work in appropriate personal protective equipment only.
NOTE: TECHNICAL INFORMATION 
Follow notes for repair work on the cooling system.
For additional information see:
17 00 NOTES FOR REPAIR WORK ON THE COOLING SYSTEM
NOTE: TECHNICAL INFORMATION 
Immobilization period-long fill of coolant! 
Do not reuse used coolant.
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.
NOTE: TECHNICAL INFORMATION 
Filling without  the vacuum filling equipment (watering can filling) is not permitted  .
If this is not observed, there is a risk of component damage or engine damage.
The filling specification must  be observed.
It is essential to visually check the vacuum filling equipment before use  to check that it is functioning correctly and clean.
It is not permissible to operate the vehicle if the filling procedure has not been fully completed. Otherwise there may be functional limitations (degradation) or overheating.
A bleeding procedure is required after a part has been exchanged in the cooling system and/or after refilling the cooling system.
NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
NOTE: TECHNICAL INFORMATION 
When the engine is stopped after the completion of trip, it may be necessary to run the electric fan. In rare cases, operation of the electric fan can last up to 11 min. This protects the components. In this case, replacing the electric fan will not remedy the problem!

Preliminary work 

WARNING: Hot surfaces  .
Risk of burning! 
  • Perform all work only on components that have cooled down.
CAUTION: Heavy component  .
Heavy components can lead to injury or damage  .
  • Remove and install heavy components with the aid of another person/other persons.
NOTE: RISK OF DAMAGE 
Electrostatic discharge  .
Damage to or destruction of electrical components  .
  • Leave the electrical components in their original packaging until they are being installed. Only use the original packaging for returning the product. Always package removed components straight away.
  • Read and comply with user information on using the associated special tool 12 7 060.
  • Only tap the housings of electrical components. Do not tap pins or multi-pin connectors directly.
  • Wear electrically conductive clothing and antistatic shoes (with ESD symbol).
  • For additional information see: 61 35... NOTES ON ESD (ELECTROSTATIC DISCHARGE) PROTECTION
NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
NOTE: TECHNICAL INFORMATION 
If the turbocharger is damaged, it is imperative to observe the additional information.
NOTE: TECHNICAL INFORMATION 
For turbocharger damage:  Check the pressure pipes, charge air cooler and intake plenum for foreign matter, damage and correct functionality.
If the oil return line is exchanged, then the connecting pipe to the oil sump must ALWAYS be cleaned, as the connecting pipe can coke.
