4.5. Electric fan
On all injector engines the fan turns on from the processor control unit, under the influence of temperature sensor which will be screwed in the soaking-up collector (from a cover of chains). On cars with carburetor engines the fan turns on at operation of the thermoswitch which will be screwed in a thermostat cover. On cars with the conditioner and (or) automatic transmission two fans are provided.
Only the elementary check is independently allowed.
