The car radiator tank (inlet and outlet tanks) holds and directs engine coolant as it flows into and out of the radiator core.
Main Functions of the Radiator Tanks
Inlet Tank (Top or Side): Receives hot coolant directly from the engine via the upper radiator hose and distributes it evenly into the core tubes.• Outlet Tank (Bottom or Opposite Side): Collects the cooled coolant after it passes through the metal fins of the Radiator (engine cooling) core and sends it back to the engine through the lower hose.
• Coolant Reservoir Connection: Houses or connects to the pressure cap and overflow/expansion lines to manage fluid volume changes and release or pull back coolant as the engine heats up and cools down.
• Structural Mount: Acts as the end-chambers (often made of durable reinforced plastic in modern cars) that seal the
