4. Cooling system
In system of cooling for maintenance of circulation of a cooling liquid it is used лопастной the water pump. The fan with an electromagnetic drive joins a thermoswitch located in sideways radiator (between both unions of fastening of hoses), at too considerable heating of the engine and is again disconnected, when the engine temperature goes down. The switch two-level. Inclusion of the first step occurs at 92–97 ° With, and switching-off at 84 91 ° S.Vtoraja a step joins at 99–105 ° With, and is switched off at 91–98 ° With.
Established independently in cooling system the broad tank provides expansion of a cooling liquid in system: at superfluous pressure the superfluous cooling liquid arrives in a broad tank. After the next fall of temperature in cooling system the cooling liquid again comes back in a radiator, and consequently, and in system.
