Preconditions 

• 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: Frostox HT-12 antifreeze/corrosion inhibitor, BMW part number 83 19 2 468 442
  • Observe the appropriate water/antifreeze mixture ratio.
  • Observe specified 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 LT coolant expansion tank

Connect filler unit to adapter connection (X)

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

Close the shutoff valve (A) again. The filler hose (1) has now been bled.

Shutoff valve (B) will remain open. Generate vacuum in coolant system for approx. 2 minutes. The end vacuum is reached at a vacuum of -0.7 to -0.95 bar. Green scale on the vacuum meter.

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 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

Shut-off valve (B) remains closed during the filling process.

To fill the cooling system, open shutoff valve (A) to filling unit container

Coolant is now added.

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

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

Remove filling unit with adapter from expansion tank.

Adjust coolant level to maximum.

Close coolant expansion tank.
