Never 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 drained and refilled.
In the case of other removal work involving the draining of part quantities of coolant, replace these quantities which have been drained with new coolant.
Cover alternator with suitable materials.
Failure to comply with this procedure may result in an alternator malfunction.
Note on ordering:
- Workshop equipment
- Workshop equipment catalogue
- Filler unit no. 81 39 2 152 473
- Collecting vessel no. 81 49 2 152 347
- Adapter: 17 0 100
Danger of injury!
Catch and dispose of emerging coolant in drip tray (1) and if necessary special tool 00 2 030 (universal hydraulic lifting equipment).
Recycling:
Observe country-specific waste disposal regulations.
If necessary, replace damaged and porous coolant hoses.
- 1) Filling unit with vacuum meter and shut-off valves
- 2) Filler hose
- 3) Coolant container
- 4) Venturi nozzle
- 5) Compressed air connection (max. 6 bar)
- 6) Outgoing-air hose (lead outgoing-air hose into a collecting container)
Requirements
- Cooling system expansion tank must be empty.
- There must be sufficiently premixed coolant in the filling unit container, 1 - 2 liters more than the vehicle filling capacity.
- Use only recommended coolant COOLING SYSTEM - OPERATING FLUIDS .
- Observe mixture ratio.
- Observe capacities.
- Position the filling unit container at the same height as the coolant expansion tank.
- Compressed-air connection with 6 bar pressure present.
- Set vehicle heater to maximum temperature.
Select adapter (Y) according to table and connect to coolant expansion tank.
Connect filler unit to adapter connection (X).
Shut-off valves (A) and (B) of the filling unit (1) must be closed.
X) Expansion tank connection
Connect venturi nozzle (1) to filling unit (2).
X) Expansion tank connection
Connect compressed air (1).
X) Expansion tank connection
Open shut-off valve (B).
The venturi nozzle produces a flow noise.
Then open shut-off valve (A) until the filling hose (1) is free of bubbles.
Close shut-off valve (A) again. The filling hose (1) is vented in this way.
Shut-off valve (B) remains open. Generate vacuum in coolant system for approx. 2 minutes. The final vacuum is reached at a vacuum of -0.7 to -0.95 bar. Green scale on the vacuum meter.
Then close shut-off valve (B) again.
Both shut-off valves (A) and (B) must be closed. Then seal Venturi nozzle (1).
The cooling system must hold the vacuum for 30 seconds. If the needle in the vacuum meter falls, this indicates a leak in the cooling system.
If the vacuum remains constant, proceed with filling.
In event of leaks, check cooling system for leaks.
Position the filling unit container at the same height as the coolant expansion tank.
Shut-off valve (B) remains closed during the filling process.
To fill the cooling system, open shut-off valve (A) to filling unit container.
Coolant is now added.
The filling process is finished when the needle in the vacuum meter is at 0 bar or no longer falls.
If necessary, reduce remaining vacuum. Open shut-off valve (B) to do so.
Remove filling unit with adapter from expansion tank.
Adjust coolant level to max.
Close coolant expansion tank.
Check function of cooling system.
Check cooling system for leaks.
