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 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 | When working on the oil, coolant or fuel circuit, protect the alternator against contamination. 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. Tightening torque, hose clamps See 17 00 1AZ. .

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.
