Air Cooling System Diagram

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 cooling system diagram.

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. Air handling unit ahu. The system needs topping up from time to time. Another air cooled engine design this from the fiat 126 and fiat 500 engines.

In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot. A device used to condition and circulate air as part of a heating ventilating and air conditioning hvac system. Open the valve and bleed the air trapped in the upper portion of the radiator. As this liquid passes through the hot engine it absorbs heat cooling the engine.

This puts your radiator higher than the rest of the cooling system and helps force the air pockets closed. You can also jack your car to bleed the air from the cooling system. A radiator pressure cap is designed to maintain pressure in the cooling system at a certain maximum pressure. Keep the radiator cap loose to help the air move out during this process.

The cooling system on liquid cooled car engines circulate a fluid through pipes and passageways in the engine. If the cooling system exceeds that pressure a valve in the cap opens to bleed the excessive pressure into the reserve tank. 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.
