Systems of cooling, heating

Specifications

The general parametres

Arrangement of gauges in the right forward part of an impellent compartment


Separate characteristics are resulted also in the text of the Head and in case of compulsion of their performance are allocated by a bold type


Design of system of cooling

Thermosiphon with лопастным the water pump. Thermostatic adjustment. With a separate broad tank. The fan with вязкостной муфтой. The additional electric fan joins and switched off by a thermoswitch

Cooling liquid

Structure

Mix of soft water (60 %) and антифризного a concentrate (40 %)

Antifriznyj concentrate

Aral Antifreeze Extra, DEA Kьhlerfrostschutz, GlycoShell, Glysantin Protect Plus, Mobil Frostschutz 600
System volume
316i, 318i6.0
320i, 323i, 328i8.4

The quantity of antifreeze added in system of cooling for maintenance of demanded frost resistance (thus as much a cooler to merge)
It is more low shown, how many antifreeze it is necessary to add to provide desirable frost resistance.
Example: Measurement on the engine 316i shows protection to temperature-10S. In this case it is necessary to merge of 2.0 l from system of a cooling liquid and instead of it to fill in 2.0 l of a pure concentrate. It will provide protection of the engine to temperature-35S.

The values resulted in the table are valid at temperature of a cooling liquid nearby +20С.
Ridge клиновые belts.

318i 6 РК x 1733 (5 РК x 950)
