Radiator - tubular-tape, with side plastic tanks
The tanks are connected to the radiator frame through a rubber sealing gasket by crimping the support plate onto the flange of the plastic tanks
On the tanks and the top plate of the radiator frame there are brackets for attaching the radiator to the car body.
On the right tank (along the direction of the car) in the lower part there is a drain plug for draining the coolant.
The expansion tank is plastic, connected by a hose to the pipe supplying cooled liquid from the radiator to the engine, and by a tube to the thermostat pipe and the left radiator tank.
The tank has a MIN mark - the lowest permissible level of coolant in the tank.
The expansion tank is closed with a screw plug that maintains increased pressure in the cooling system.
The expansion tank plug, which hermetically closes the cooling system, has two valves: steam, opening at a pressure of 80-110 kPa (0.8-1.1 kgf) and air, opening at a vacuum of 1.0-10 kPa (0 .01—0.1 kgf/cm 2).
