Pressurized Water Cooling System In Automobile

Pressurized cooling systems radiator caps for pressurized automotive cooling systems.

Pressurized water cooling system in automobile.

When the cooling system s pressure exceeds the safety limit the cap s safety valve opens to discharge the extra coolant. The boiling point of water increases when the water is placed under pressure. Pressurized water systems are relatively new to the short track and stock car world. 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.

Vehicles these days have a recovery tank to store that discharged coolant. 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. 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. Flushing a car s cooling system the cap acts as a pressure and safety valve.

This technology has been around in f 1 and indy cars for many years. The cap is actually a pressure release valve and on cars it is usually set to 15 psi. Under pressure the boiling point of the coolant is raised considerably. A radiator or cooling system pressure test is useful when finding a radiator leak or a blown head gasket.

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. When the fluid in the cooling system heats up it expands causing the pressure to build up. The same way a pressure cooker increases the boiling temperature of water. The cooling system consists of several main components that each perform a different task.

It s more efficient and more failsafe than. In order to prevent the coolant from boiling the cooling system is designed to be pressurized.
