Air Cooling System Diagram

A radiator pressure cap is designed to maintain pressure in the cooling system at a certain maximum pressure.

If the cooling system exceeds that pressure a valve in the cap opens to bleed the excessive pressure into the reserve tank. Another air cooled engine design this from the fiat 126 and fiat 500 engines. 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.

The cooling system on liquid cooled car engines circulate a fluid through pipes and passageways in the engine. The system needs topping up from time to time. An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers. 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.

A device used to condition and circulate air as part of a heating ventilating and air conditioning hvac system. The air is sucked into the engine compartment through a tunnel that runs beneath the rear shelf. As this liquid passes through the hot engine it absorbs heat cooling the engine. You can also jack your car to bleed the air from 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. This puts your radiator higher than the rest of the cooling system and helps force the air pockets closed. In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot.
