| Cooling system design |
| Thermosiphon with the bladed water pump. Thermostatic adjustment. With a separate broad tank. The fan with the viscous coupling. The additional electric fan joins and switched off by a thermoswitch |
| Cooling liquid |
| Structure
| mix of soft water (60%) and antifrizny concentrate (40%) |
| Antifrizny concentrate |
| Aral Antifreeze Extra, DEA Khlerfrostschutz, GlycoShell, Glysantin Protect Plus, Mobil Frostschutz 600 |
| Volume of system |
| 316i, 318i | 6.0 |
| 320i, 323i, 328i | 8.4 |
| 320d | 7.0 |
| The amount of antifreeze added to the cooling system for ensuring the demanded frost resistance (thus as much a cooler to merge) |
| It is shown below, how many antifreeze it is necessary to add to provide desirable frost resistance. |
| Example: Measurement on the engine 316i shows protection up to the temperature of -10 °C. In this case it is necessary to merge 2.0 l of cooling liquid from system and instead of it to fill in 2.0 l of a pure concentrate. It will provide protection of the engine up to the temperature of -35 °C. |
| | The values given in the table are valid at a temperature of cooling liquid about +20 °C.
