It keeps the engine from running too hot or too cold once it is warmed up.
Pressurized water cooling system in automobile.
When the fluid in the cooling system heats up it expands causing the pressure to build up.
In order to prevent the coolant from boiling the cooling system is designed to be pressurized.
Pressurized water systems are relatively new to the short track and stock car world.
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.
It s more efficient and more failsafe than.
Of the two valves one prevents the creation of a vacuum the other limits the pressure.
The cooling system consists of several main components that each perform a different task.
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.
Under pressure the boiling point of the coolant is raised considerably.
This technology has been around in f 1 and indy cars for many years.
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.
A radiator or cooling system pressure test is useful when finding a radiator leak or a blown head gasket.
Pressurized cooling systems radiator caps for pressurized automotive cooling systems.
The cooling system in your vehicle is designed to keep the engine at a consistent temperature.
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.
The same way a pressure cooker increases the boiling temperature of water.
