Fill the cooling system with the vacuum filling unit

WARNING: This page is about a different car, the 2023 BMW X5, 2022 BMW X5, 2021 BMW X5, 2020 BMW X5, and 2019 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: DANGER
High-voltage system .
The high-voltage system operates on the basis of hazardous, electrical voltage and high currents. Mortal hazard through electric shock!

All work on the high-voltage system may only be carried out by specially trained and technically experienced personnel.
For additional information see:
SAFETY INSTRUCTIONS ON HANDLING HYBRID CARS .

Vacuum filling equipment

Vacuum filling equipment with pressure gauge and shutoff valves
Filling hose
Fluid tank with coolant
Venturi nozzle
Compressed air connection (maximum of 6 bar)
Out-going hose (lead out-going hose into a collecting vessel)

Prerequisite

The fluid tank of the vacuum filling equipment must have a sufficient quantity of premixed coolant, 1 l to 2 l more than the specified capacity for the vehicle. The fluid tank of the vacuum filling equipment must be positioned at the same height as the coolant expansion tank.

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
Follow notes for repair work on the cooling system. For additional information see: NOTES FOR WORKING ON THE COOLING SYSTEM

NOTE: TECHNICAL INFORMATION
Make sure that the ignition (terminal 15) is switched off prior to creating the vacuum with the vacuum filling equipment.

NOTE: TECHNICAL INFORMATION
G07 with S4NNA: The air conditioning control panel must be switched off.

Choose the correct coolant for filling.

In general, a vehicle has to be filled with the coolant with which it is delivered from the factory.

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

NOTE: RISK OF DAMAGE
Damage to the engine or components in high-voltage vehicles
Using the incorrect coolant may lead to corrosion or gel formation in the coolant circuit.

Only use coolant that has 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 allow any statement about coolant compatibility.
Selection of the correct coolant exclusively via the part number.

Fill the cooling system with special tool 2 152 473 .

Select a suitable adapter (Y) from the set of special tools 0 494 417 (17 0 100) :

Type	Engine	Adapter (Y) from 17 0 100
G05/G06/G07	B47/B57/B48/B58	17 0 105

Open shutoff valve (B).
The venturi nozzle produces a flow noise.

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.

Courtesy of BMW OF NORTH AMERICA, INC.
Check coolant hoses for porosity; if necessary replace porous coolant hoses.
NOTE: TECHNICAL INFORMATION
The coolant hoses contract during vacuum build-up.
After a vacuum of -0.7 to -0.95 bar has been reached in the coolant circuit (duration approximately 2 minutes), close the shutoff valve (B).

Check whether the 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 30 seconds.

Result

Vacuum drops.

Measure

Look for the leak, repair it and start the filling procedure from the beginning.

Check

The vacuum in the coolant circuit must be maintained for at least 30 seconds.

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).

Remove the vacuum filling equipment with the adapter from the coolant expansion tank.
Adjust the coolant level to the maximum mark.
After filling the cooling system with the vacuum filling equipment, also perform the cooling system bleeding procedure.
