Separate characteristics are also given in the text of the Chapter and, if they are mandatory, are highlighted in bold
Cooling system design | |
Thermosyphon with a vane water pump. Thermostatic adjustment. With separate expansion tank. Viscous fan. Optional electric fan switched on and off by thermal switch | |
Coolant | |
Compound | soft water mixture (60%) and antifreeze concentrate (40%) |
Antifreeze concentrate | |
Aral Antifreeze Extra, DEA Khühlerfrostschutz, GlycoShell, Glysantin Protect Plus, Mobil Frostschutz 600 | |
System volume | |
316i, 318i | 6.0 |
320i, 323i, 328i | 8.4 |
320d | 7.0 |
The amount of antifreeze added to the cooling system to provide the required frost resistance (while draining the same amount of coolant) | |
The following shows how much antifreeze should be added to achieve the desired frost resistance. | |
Example:Measurement on the 316i engine shows protection down to -10°C. In this case, it is necessary to drain 2.0 liters of coolant from the system and fill in 2.0 liters of pure concentrate instead. This will protect the engine down to -35°C. | |
The values given in the table are valid at a coolant temperature of approx. +20°C. | |
