Attention!

Service life 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.

Attention!

You must protect the alternator against contamination by coolant when carrying out repair work on the coolant circuit.

Cover alternator with suitable materials.

Failure to comply with this procedure may result in an alternator malfunction.

Information for ordering through BMW:

Vacuum filling equipment, order number 81 39 2 152 473
Drip pan, order number 81 49 2 152 347
Adapter: 17 0 100

Attention!

Risk of slipping due to coolant on the floor.

Injury hazard!

Catch and dispose of emerging coolant in drip tray (1) and, if needed, special tool 00 2 030 (universal jack).

Recycling:

Observe country-specific waste disposal regulations.

Attention!

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

If necessary, replace damaged and porous coolant hoses.

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)

Preconditions

Cooling system expansion tank must be empty.
There must be sufficient pre-mixed coolant in the vacuum filling equipment container, 1-2 liters more than the prescribed vehicle filling capacity.
Use only recommended coolant.
Observe the appropriate water/antifreeze mixture ratio.
Observe CAPACITIES .
Position vacuum filling equipment 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).

Shutoff valves (A) and (B) of the vacuum filling equipment (1) must be closed.

(X) Expansion tank connection

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. Create vacuum in coolant circuit for about 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.

Check for tightness if there are leaks.

Attention!

There must be sufficient pre-mixed coolant in the vacuum filling equipment container: 1-2 liters more than the vehicle's filling capacity.

Position vacuum filling equipment 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 filling equipment 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 the following vehicles:

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 sealing cap of the coolant expansion tank 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 on ignition.
Switch on low-beam headlight.
Set heating to maximum temperature. Take back blower to smallest stage.
Driving dynamics control must not be set to ECO PRO!
Press accelerator pedal for 10 seconds to floor. Engine must not be started.
The bleeding procedure was started by pressing the accelerator pedal and takes about 12 minutes (the electric coolant pump was activated and switches off automatically after about 12 minutes).
Then adjust fill level in coolant expansion tank to maximum.
Check cooling system for tightness.
If the cooling system bleeding procedure has to be performed again, deactivate the DME completely (remove ignition key for about three minutes). Then repeat from point 3.

Check function of cooling system.

Check cooling system for tightness.
