4. Cooling system

Specifications

The water pump, radiator with a cross stream, the radiator fan with an electric wire, the thermostat, a heater radiator, hoses and sensors are a part of the cooling system of the closed type.

The radiator fan with an electric wire turns on at operation of the contact sensor of temperature.

On models with automatic transmission a part of liquid circulates through a cooler of transmission liquid.
