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 |
System volume |
316i, 318i | 6.0 |
320i, 323i, 328i | 8.4 |
320d | 7.0 |
The amount of antifreeze added to the cooling system for ensuring the required frost resistance (at the same time as much a cooler to merge) |
It is shown below how many antifreeze should be added 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. Ridge maple belts. | |
318i | 6 PK x 1733 (5 PK x 950) |
320d | 5 PK x 2030 (5 PK x 836) |
320i, 323i, 328i | 6 PK x 1538 (5 PK x 863) |
