Air Cooling System Diagram

As this liquid passes through the hot engine it absorbs heat cooling the engine.

Air cooling system diagram.

Open the valve and bleed the air trapped in the upper portion of the radiator. 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. This puts your radiator higher than the rest of the cooling system and helps force the air pockets closed.

An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers. A device used to condition and circulate air as part of a heating ventilating and air conditioning hvac system. Once the engine has cooled off a negative pressure begins to develop in the cooling system. 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.

In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot. The cooling system on liquid cooled car engines circulate a fluid through pipes and passageways in the engine. 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. 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.

The air is sucked into the engine compartment through a tunnel that runs beneath the rear shelf. The system needs topping up from time to time. Air handling unit ahu.
