Air Cooling System Diagram

If the cooling system exceeds that pressure a valve in the cap opens to bleed the excessive pressure into the reserve tank.

Air cooling system diagram.

The air is sucked into the engine compartment through a tunnel that runs beneath the rear shelf. Open the valve and bleed the air trapped in the upper portion of the radiator. The system needs topping up from time to time. 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.

Keep the radiator cap loose to help the air move out during this process. Air handling unit ahu. An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers. 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. 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. In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot. 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. Another air cooled engine design this from the fiat 126 and fiat 500 engines. A device used to condition and circulate air as part of a heating ventilating and air conditioning hvac system.
