Pressurized Water Cooling System In Automobile

Pressurized cooling systems radiator caps for pressurized automotive cooling systems.

Pressurized water cooling system in automobile.

It is generally a limitation of most cooling systems that the cooling fluid not be allowed to boil as the need to handle gas in the flow greatly complicates design. However too much pressure will cause hoses and other parts to burst so a system is needed to relieve pressure if it exceeds a certain point. In order to prevent the coolant from boiling the cooling system is designed to be pressurized. It s more efficient and more failsafe than.

The cap is actually a pressure release valve and on cars it is usually set to 15 psi. The boiling point of water increases when the water is placed under pressure. Vehicles these days have a recovery tank to store that discharged coolant. When the cooling system s pressure exceeds the safety limit the cap s safety valve opens to discharge the extra coolant.

This technology has been around in f 1 and indy cars for many years. The cooling system in your vehicle is designed to keep the engine at a consistent temperature. Pressurized water systems are relatively new to the short track and stock car world. Under pressure the boiling point of the coolant is raised considerably.

The cooling system consists of several main components that each perform a different task. Flushing a car s cooling system the cap acts as a pressure and safety valve. Of the two valves one prevents the creation of a vacuum the other limits the pressure. If you have had any parts replaced on your cars cooling system radiator waterpump new hoses ect then there is a chance that your cooling system has air trapped in it and this could make your cars cooling system operate poorly or in worst cases minic the symptoms of a cracked head.

A radiator or cooling system pressure test is useful when finding a radiator leak or a blown head gasket. The same way a pressure cooker increases the boiling temperature of water.
