Pressurized Water Cooling System In Automobile

A radiator or cooling system pressure test is useful when finding a radiator leak or a blown head gasket.

Pressurized water cooling system in automobile.

The boiling point of water increases when the water is placed under pressure. Pressurized cooling systems radiator caps for pressurized automotive cooling systems. It s more efficient and more failsafe than. When the cooling system s pressure exceeds the safety limit the cap s safety valve opens to discharge the extra coolant.

The cooling system consists of several main components that each perform a different task. Vehicles these days have a recovery tank to store that discharged coolant. The same way a pressure cooker increases the boiling temperature of water. The cap is actually a pressure release valve and on cars it is usually set to 15 psi.

When the fluid in the cooling system heats up it expands causing the pressure to build up. 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. Of the two valves one prevents the creation of a vacuum the other limits the pressure. Under pressure the boiling point of the coolant is raised considerably.

Pressurized water systems are relatively new to the short track and stock car world. It keeps the engine from running too hot or too cold once it is warmed up. In order to prevent the coolant from boiling the cooling system is designed to be pressurized. This tool attaches to the top or the radiator or coolant reservoir and enables air pressure to be pumped into the system including the engine block cylinder heads coolant hoses heater core and radiator.

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. Flushing a car s cooling system the cap acts as a pressure and safety valve.
