17 00 009 Checking cooling system for leaks (S65)
| WARNING | Danger of scalding! Only perform this work after engine has cooled down. |
Protective measures/rules of conduct
- 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 2 030 00 2 030 DEVICE (universal hydraulic lifter).
Recycling
Observe country-specific waste-disposal regulations.
Scheme 42
Checking pressure drop in cooling system
Open cap on coolant expansion tank. Fit special tools 17 0 101/17 0 113.
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 43
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.

17 00 005 Draining and adding coolant (S65)
| WARNING | Risk of scalding! Only carry out repair work on the cooling system after the engine has cooled down! Risk of skidding due to coolant on the floor. |
Protective measures/rules of conduct
- Wear safety goggles
- Wear protective gloves
- Observe national/country-specific regulations
| 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 | 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 002030 DEVICE (universal hydraulic lifting equipment).

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).

17 00... Notes on retrofitting a trailer towing device
Starting with delivery of the E90, in certain vehicle types, the size of the electric cooler fan will be linked to the optional extra trailer tow hitch or trailer provision.
A larger fan may therefore be required for retrofits.
The larger fan is necessary to ensure mountain driving with a full trailer load in accordance with BMW-internal specifications. Otherwise the engine electronics will detect possible overheating of the cooling system and activate protective functions.
For the customer, this involves impaired A/C output, automatic transmission and engine power. These will be continuously reduced, which in the end may result in the vehicle coming to a standstill in the mountain area.
00 Safety information for working on vehicles with automatic engine start-stop function (MSA)
| WARNING | If the engine hood/bonnet contact is pulled upwards (workshop mode), the information "switch closed" is output. The automatic engine start-stop function is active. An automatic engine start is possible. |
Observe safety precautions when working on MSA vehicles
Before carrying out practical work on the engine, always ensure that the MSA functionality is deactivated so as to prevent automatic engine starting while work is being carried out in the engine compartment.
MSA function is deactivated by
- Deactivate MSA by means of button (1) in passenger compartment
- Open seat belt buckle and driver's door
Scheme 52
Scheme 53
- Open engine bonnet/hood and ensure that engine hood/bonnet contact is not in workshop mode Workshop mode A = 10 mm Basic setting (engine hood/bonnet open) B = 7 mm To make sure that the engine hood/bonnet contact is at the basic setting, if necessary press the hood/bonnet contact up to the limit position before starting work and slowly release.
