    The radiator transfers the heat from the fluid inside to the air outside, thereby cooling the fluid, which in turn cools the engine.

    Radiates.

    On a liquid cooled engine, it cools and circulates coolant. Coolant heated by wasted heat  in combustion chambers that would otherwise overeat and damage engine.   The coolant is kept at a certain temp for optimum performance. Excess heat goes to ambient air.  It needs to hold it under 15 PSI or so at about  240   degrees also. 

    If coolant were to flash to atmosphere at this temp,  it would boil away.  Holding it at pressure allows more heat  to be exchanged,.

    Model T's and some others had NO water pump. Used a high up radiator that used principle, hot water rises  to top, the cooled water sinks to bottom and back to engine.  This plus the syphon created circulated the water pretty well. Needed a huge radiator, though. ID recall if T's even had a Fan. If not, engine temp  would vary by ambient temp and car's speed.  affecting  warm up, overhearing,  performance and mileage. I SEE Model Ts around town at some street corners. They are Still Out there.

    A teacher told stories of P-40's taking just One   hit in radiator and forced down. Meanwhile,  air cooled radial engines like  in a Mitsubishi  A3-M  would fly on one Less cylinder

    Since a rad resembles a condenser worm in its operation, , some moonshiners used old radiators. These caused lead poisoning. A class shiner uses copper tubing and lead free solder. This is  why IRS regulates  distilled spirits, for your safety.

    Technically your car has two radiator's. One behind the grille which transfers heated coolant to a lower temperature for the water pump to force the coolant #1. back through the engine block then the cylinder heads to the thermostat or: #2. back through the cylinder heads then the engine block to the thermostat then back through the radiator.

    The second radiator is referred as the heater core. When you start a cold engine, the thermostat is closed and the water pump circulates the coolant through the engine block, cylinder heads *and heater core only. When you turn on the heater blower motor air is forced through the heater core to warm the inside of the car. The engine thermostat does not crack open till the coolant temperature matches the temperature stamped on the thermostat at which time the coolant circulates through the radiator to lower the temperature of the coolant.

    It's an intercooler. 

    Engine coolant circulates through it, and heat is removed from the coolant (or added to the coolant) by the ambient air temperature. 

    It's a water tube intercooler.

    Its the overflow chamber for blinker fluid. Be sure to top it off with 5w30 full synthetic blinker fluid once a month. Also its best to open it right after a long drive while its still hot, so that the steam can scald you in the face - that's how you know its working.
