Radiator - tubular-tape, with side plastic tanks
The tanks are connected to the core of the radiator through a rubber seal by crimping the base plate along the flange of the plastic tanks
On the tanks and the upper plate of the radiator core there are brackets for attaching the radiator to the car body.
On the right tank (in 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 a pipe supplying cooled liquid from the radiator to the engine, and a pipe - to the thermostat pipe and the left radiator tank.
There is a MIN mark on the tank - the lower 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 plug of the expansion tank, which hermetically closes the cooling system, has two valves: a steam valve that opens at a pressure of 80–110 kPa (0.8–1.1 kgf.) and an air valve that opens at a vacuum of 1.0–10 kPa (0 .01—0.1 kgf/cm2).
