These fins transfer the heat in the tubes into the air stream to be carried away from the vehicle. On each end of the radiator core is a tank usually made of plastic that covers the ends of the radiator On most modern radiators the tubes run horizontally with the plastic tank on either side. On other cars the tubes run vertically with the tank on the top and bottom. On older vehicles the core was made of copper and the tanks were brass. The new aluminum-plastic system is much more efficient not to mention cheaper to produce. On radiators with plastic end caps there are gaskets between the aluminum core and the plastic tanks to seal the system and keep the fluid from leaking out. On older copper and brass radiators the tanks were brazed a form of welding in order to seal the radiator. inlet Tank Q-Aing Gasket O-Aing Gasket Illustration provided by the Notional Autamotwe Radiator Service Association The tanks whether plastic or brass each have a large hose connection one mounted towards the top of the radiator to let the coolant in the other mounted at the bottom of the radiator on the other tank to let the coolant back out. On the top of the radiator is an additional opening that is capped off by the radiator cap. More on this later. Another component in the radiator for vehicles with an automatic transmission is a separate tank mounted inside one of the tanks. Fittings connect this inner tank through steel tubes to the automatic transmission. Transmission fluid is piped through this tank inside a tank to be cooled by the coolant flowing past it before returning the the .
