Air Cooling System Diagram
The cooling system on liquid cooled car engines circulate a fluid through pipes and passageways in the engine.
Air cooling system diagram. Open the valve and bleed the air trapped in the upper portion of the radiator. Keep the radiator cap loose to help the air move out during this process. After the fluid leaves the engine it passes through a heat exchanger or radiator which transfers the heat from the fluid to the air blowing through. Air handling unit ahu.
The system needs topping up from time to time. A radiator pressure cap is designed to maintain pressure in the cooling system at a certain maximum pressure. As this liquid passes through the hot engine it absorbs heat cooling the engine. Another air cooled engine design this from the fiat 126 and fiat 500 engines.
An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers. Later cars have a sealed system in which any overflow goes into an expansion tank from which it is sucked back into the engine when the remaining liquid cools. This puts your radiator higher than the rest of the cooling system and helps force the air pockets closed. Once the engine has cooled off a negative pressure begins to develop in the cooling system.
You can also jack your car to bleed the air from the cooling system. The cooling system used on the most known air cooled engine the vw beetle air is drawn into the ducting by the fan and passes through an oil cooler before flowing over the cylinder heads and barrels. In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot.
