Protective measures/rules of conduct
| WARNING | Danger of scalding! Only perform this work after engine has cooled down. Wear protective goggles and gloves. |
- Wear protective goggles
- Wear protective gloves
- Observe national/country-specific regulations
| IMPORTANT | Risk of slipping due to coolant on the floor. Danger of injury! |
Catch and dispose of drained coolant in drip tray (1) and if necessary special tool 00-2030 DEVICE (universal hydraulic lifter).
Recycling
Observe country-specific waste-disposal regulations.
Scheme 9
Checking pressure drop in cooling system
Open cap on coolant expansion tank. Fit special tool 17-0100 TESTER .
Build up gauge pressure of 2 bar, wait approx. 2 minutes.
Cooling system is impervious to leaks if pressure drop is max. 0.1 bar.
Scheme 10
Checking pressure relief valve in cap
Note. Coolant residue can cause the pressure relief valve in the cap to stick, therefore repeat the check procedure on the cap 2- 3 times.
Screw cap (1) onto special tool.
Build up pressure with special tool hand pump; observe pressure gauge to ascertain when opening pressure is achieved.
Scheme 11
| WARNING | Risk of scalding! Only carry out repair work on the cooling system after the engine has cooled down! |
| 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 partial quantities of coolant, replace these quantities which have been drained with new coolant. |
Installation note
Use only recommended coolant and observe mixture ratio. See COOLING SYSTEM - OPERATING FLUIDS .
- Wear safety goggles
- Wear protective gloves
- Observe national/country-specific regulations
| IMPORTANT | For dirt contamination of the cooling system (e.g. by engine oil), the cooling system must be rinsed with water until all dirt contamination is removed! |
| IMPORTANT | Risk of skidding due to coolant on the floor. |
Danger of injury!
Catch and dispose of drained coolant in drip tray (1) and if necessary special tool 00-2030 DEVICE (universal hydraulic lifting equipment).
Recycling
Observe country-specific waste disposal regulations.

17 00... Instructions for working on cooling system
| WARNING | Danger of scalding! Work on the cooling system should only be carried out when the engine has cooled down. |
| IMPORTANT | Wear protective gloves and safety goggles. |
| 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 partial quantities of coolant, replace these quantities which have been drained with new coolant. |
| IMPORTANT | Open cooling system only when it has cooled down. Opening the cooling system while hot can result in air entering the system. This can cause overheating with permanent damage to the engine. |
| IMPORTANT | You must protect the alternator against contamination before carrying out any work on the cooling circuit. Cover alternator with suitable materials. Failure to comply with this procedure may result in an alternator malfunction. |
| IMPORTANT | Do not fill coolant expansion tank over MAX level as overfilling will cause the coolant to overflow. This may give rise to traces of residual coolant on the expansion tank or in the engine compartment and wrongly suggest possible leakages. |
Recycling
Catch and dispose of drained coolant.
Observe country-specific waste-disposal regulations.
Note. To disconnect coolant hoses, use commercially available disconnect tools such as HAZET brand tools (see table).

Catch and dispose of emerging coolant in drip tray (1) and if necessary special tool 00-2030 DEVICE (universal hydraulic lifting equipment).
Recycling
Observe country-specific waste disposal regulations.
| IMPORTANT | Check all the coolant hoses before filling the cooling system with the vacuum filling unit. If necessary, replace damaged and porous coolant hoses. |
Scheme 20
- 1) Filling unit with vacuum meter and shut-off valves
- 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)
Requirements
- 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 and observe mixture ratio and capacities. See «COOLING SYSTEM - OPERATING FLUIDS»(/bmw/m6/e63e64-2005-2010/remont/cooling-system-mechanical/#cooling-system-operating-fluids) .
- 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 coolant expansion tank.
Connect filler unit to adapter connection (X).
Scheme 21
Shut-off valves (A) and (B) of the filling unit (1) must be closed.

Scheme 24
Open shut-off valve (B).
The venturi nozzle produces a flow noise.
Scheme 25
Then open shut-off valve (A) until the filling hose (1) is free of bubbles.
Close shut-off valve (A) again. The filling hose (1) is vented in this way.
Scheme 26
Shut-off valve (B) remains 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 on the vacuum meter.
Note. The coolant hoses contract during vacuum build-up.
Then close shut-off valve (B) again.
Scheme 27
Both shut-off valves (A) and (B) must be closed. Then seal Venturi nozzle (1).
Scheme 28
The cooling system must hold the vacuum for 30 seconds. 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.
Scheme 29
| IMPORTANT | There must be sufficiently premixed coolant in the filling unit container, 1 - -2 liters more than the vehicle filling capacity. Position the filling unit 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 shut-off valve (A) to filling unit container.
Scheme 30
Coolant is now added.
The filling process is finished when the needle in the vacuum meter is at 0 bar or no longer falls.
If necessary, reduce remaining vacuum. Open shut-off valve (B) to do so.
Scheme 31
Remove filling unit with adapter from expansion tank.
Scheme 32
Adjust coolant level to max.
Close coolant expansion tank.
Check function of cooling system.
Check cooling system for leaks.

Only when filling!
- Perform filling operation slowly.
- Set heater to maximum temperature and turn fan down to lowest speed.
- Start engine and run at idle speed.
- Fill coolant expansion tank with 250 ml above max. (250 ml correspond to A=18 mm).
- Run engine for 15 mins.
- Cooling system vents itself.
- Coolant level must drop to marking.
