IMPORTANT:

Lifetime coolant filling:

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.

IMPORTANT: You must protect the alternator against contamination by coolant when carrying out repair work on the cooling circuit.
Cover alternator with suitable materials.
Failure to comply with this procedure may result in an alternator malfunction.

Workshop equipment information:

Vacuum filling unit, order number 81 39 2 152 473
Collecting vessel, order number 81 49 2 152 347
Adapter: 17 0 100

WARNING: Risk of slipping due to coolant on the floor.

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.

IMPORTANT: All coolant hoses must be checked before filling cooling system with vacuum filling unit.

If necessary, replace damaged and porous coolant hoses.

Compressed air connection (max. 6 bar)
Outgoing-air hose (lead outgoing-air hose into a collecting container)

Preconditions

Cooling system expansion tank must be empty.
There must be sufficient premixed coolant in the vacuum filler device container, 1-2 liters more than the filling capacity prescribed for the vehicle.
- Use only recommended COOLANT .
- Observe appropriate water/antifreeze mixture ratio.
- Observe CAPACITIES .
Position the vacuum filler device container at the same height as the coolant expansion tank.
Compressed-air connection with 6 bar pressure present.
Set heating to maximum temperature.

Select adapter (Y) according to table and connect to coolant expansion tank.

Connect vacuum filling unit to adapter connection (X).

Open shutoff valve (B).

The venturi nozzle produces a flow noise.

Then open shutoff valve (A) until the filling hose (1) is free of bubbles.

Close shutoff valve (A) again. The filling hose (1) is vented in this way.

Shutoff valve (B) will remain 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 in the pressure gauge.

NOTE: The coolant hoses contract during vacuum build-up.

Then close shutoff valve (B) again.

Both shutoff valves (A) and (B) must be closed. Then seal Venturi nozzle (1).

The cooling system must hold the vacuum for 30 s. If the needle in the pressure gauge drops, this indicates a leak in the cooling system.

If the vacuum remains constant, proceed with filling.

In the event of leaks, check cooling system for leaks.

IMPORTANT: There must be sufficiently premixed coolant in the vacuum filler device container, 1-2 liters more than the filling capacity prescribed for the vehicle.
Position the vacuum filler device 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 shutoff valve (A) to vacuum filler device container.

Coolant is now added.

The filling procedure is finished when the needle in the pressure gauge is at 0 bar or no longer falls.

If necessary, reduce remaining vacuum. Open shutoff valve (B) to do so.

Remove vacuum filling unit with adapter from expansion tank.

Adjust coolant level to maximum.

Close coolant expansion tank.

After the cooling system has been filled with the vacuum filling unit, another bleeding procedure must be performed for vehicles with an electric coolant pump:

NOTE: Do not open the coolant expansion tank sealing cap during the bleeding procedure.
Switch on the low-beam headlights to perform the bleeding procedure. If the low-beam headlights are not switched on, the ignition (Terminal 15) will switch off automatically after a certain period of time and interrupt the bleeding procedure.

Connect battery charger.
Switch the ignition on.
Switch on low-beam headlight.
Set heating to maximum temperature. Take back blower to smallest stage.
Driving experience switch must not be set to ECO PRO!
Press accelerator pedal for 10 seconds to floor. Engine must not be started.
The venting procedure is started when the accelerator pedal is pressed and takes approx. 12 minutes. (Electric coolant pump was activated and shuts down automatically after approx. 12 min).
Then adjust filling level in coolant expansion tank to maximum.
Check cooling system for tightness.
If the cooling system bleeding has to be performed again, deactivate DME completely (remove ignition key for approx. 3 minutes). Then repeat from point 3.

Check function of cooling system.

Check cooling system for tightness.
