Vacuum filling equipment - connected to the coolant expansion tank

Vacuum filling equipment with pressure gauge and shutoff valves
Filling hose
Fluid tank with coolant
Venturi nozzle
Compressed air connection (7 bar)
Exhaust hose (route exhaust hose into a collecting vessel)

Precondition

Sufficient premixed coolant must be present in the fluid tank of the vacuum filling equipment, 1 I to 2 I more than the filling capacity prescribed for the vehicle. The fluid tank of the vacuum filling equipment must be positioned at the same height as the coolant expansion tank.

The vacuum filling equipment must be functional and free of dirt.

NOTE: TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant.
The coolant must be replaced when replacing and removing components which depend on the anti-corrosion effect of 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
Notes for working on the engine cooling system.
For additional information see: NOTES FOR WORKING ON THE COOLING SYSTEM .

NOTE: TECHNICAL INFORMATION
It must be ensured that the ignition (terminal 15) is switched off before filling with the vacuum filling equipment.

Choose the correct coolant for filling.

In general, a vehicle must be filled with the coolant with which it was delivered from the plant.

G48 (Blue) (BMW LC-87)
Must not be mixed with i3 Coolant or G30 MINI Diesel W16 or HT12 (Pink), HT12 (Green).
i3 Coolant (Blue) (BMW LC-13)
Is exclusively used for i3 heater circuit. i3 Coolant must not be added to other coolant circuits or be mixed with other coolants.
HT12 (Pink) (BMW LC-18)
Must not be mixed with i3 Coolant or G30 MINI Diesel W16 or G48 (Blue).
HT12 (Green) (BMW LC-18)
Must not be mixed with i3 Coolant or G30 MINI Diesel W16 or G48 (Blue).
G30 (Pink) (BMW LC-07)
May only be used for MINI Diesel W16. G30 must not be added to other coolant circuits or mixed with other coolants.

NOTE: RISK OF DAMAGE
Damage to the engine or components in high-voltage vehicles
If the wrong coolant is used, corrosion or gelling can occur in the coolant circuit.

Only use coolants that have been approved for the specific vehicle.
Only fill the vehicle with the coolant with which it was delivered ex works.
Only mix compatible coolants. The color does not indicate the compatibility of coolants.
Selection of the correct coolant exclusively via part number.

NOTE: TECHNICAL INFORMATION
When using vacuum filling equipment to fill the coolant circuit, you must use special tool 5 A31 EF2 (strainer) to protect the inside of the coolant circuit from contaminants.

Connect special tool (2) 5 A31 EF2 to the vacuum filling equipment (1).
Connect the special tool (2) with the appropriate adapter (3) from the set of special tools 0 494 417 (17 0100)
Fill the cooling system with special tool 2 152 473.

Select a suitable adapter (Y) from the set of special tools 0494 417 (17 0100):

Open shutoff valve (A) until the filling hose (1) is full without bubbles.
Close the shutoff valve (A) again.
» The filling hose (1) has now been bled.

Check the coolant hoses for porosity and, if necessary, replace them.
NOTE: TECHNICAL INFORMATION
During vacuum build-up, the coolant hoses will contract.
After a vacuum of -0.8 to -0.95 bar is reached in the coolant circuit (approx. 2 min), close shutoff valve (B).

Check whether shutoff valves (A) and (B) are closed.
Disconnect the Venturi nozzle (1).

Check
The vacuum in the coolant circuit must be maintained for at least 2 min.

Result

» Vacuum drops.

Measure
Search for leaks, repair them, and start the filling procedure from the beginning.
Check
The vacuum in the coolant circuit must be maintained for at least 2 min.

Result

» Vacuum remains constant.

Measure
Continue with filling.
Keep shutoff valve (B) closed during the filling process.
To fill the cooling system, open shutoff valve (A) to the fluid tank of the vacuum filling equipment.

Stop the filling procedure when the needle in the pressure tester is on 0 bar or it no longer drops.
If necessary, reduce remaining vacuum. Open the shutoff valve (B).

Courtesy of BMW OF NORTH AMERICA, INC.
Remove the vacuum filling equipment with the adapter from the coolant expansion tank.
Adjust the coolant level to the maximum mark.
After filling the engine cooling system with the vacuum filling equipment, also carry out the cooling system bleeding procedure.
