Coolant, or antifreeze, is essential to regulating the temperature of your vehicle. It’s also extremely toxic and designed to stay inside a closed system. If you’re seeing an overflow, it could be due to a radiator cap, thermostat, water pump, or radiator malfunction.

How do I lower the pressure in my cooling system?
The only way to change this pressure is to increase/decrease pump flow or add or remove restriction from the system. The water component of coolant boiling, in the hottest areas of the engine, creates expansive vapor, which further pressurizes the system.
Why is there pressure in my coolant?
When there's a leak in the cooling system, the pressure of the liquid drops and so does the boiling point of the coolant/antifreeze. Cooling systems are pressurised to raise the boiling point of the fluid, with the pressure cap and the overflow helping to raise the temperature at which the coolant/antifreeze boils.
What is normal cooling system pressure?
Most radiator pressure caps keep the system pressure at 16 PSI so the engine coolant can get considerably hotter without the fear that it will boil off. If there is no pressure in the cooling system, the coolant will boil off.
Why Coolant Comes Out Of Radiator Cap Or Overflow Tank Reservoir On A Car
Is overflowing coolant bad?
This is where the real dangers of overfilling your coolant lie. Hot coolant leaking throughout your engine bay can cause serious damage to wiring and electrical components. If you do end up with a burst hose, your engine could be starved of coolant and cause some pretty big problems.
How do I reduce the pressure in my coolant system?
The only way to change this pressure is to increase/decrease pump flow or add or remove restriction from the system. The water component of coolant boiling, in the hottest areas of the engine, creates expansive vapor, which further pressurizes the system.
What causes high pressure build up in cooling system?
Leaks. The most common cause of radiator leaks is leaky hoses, but you can have leaks in the radiator itself, too, which can be a bigger problem. The coolant continually running from your radiator to your hot, running engine and back again creates a lot of pressure.

Should there be pressure in coolant system?
It needs to hold pressure up to 1 bar or14. 5psi. At normal temp the in-system pressure will be around 10psi, but there can be transients when high engine load causes momentary increases in coolant temp, and thereby pressure.
What is an over pressurizing cooling system?
An over pressurized radiator is usually the first sign to a larger mechanical issue. Most often it is the first sign to a blown head gasket. More rarely it is the result of a worn radiator cap. It is essential that a new cap always accompany a new radiator.
Why Is My Coolant Reservoir Overflowing?
Is it normal to have pressure in coolant reservoir?
It needs to hold pressure up to 1 bar or14. 5psi. At normal temp the in-system pressure will be around 10psi, but there can be transients when high engine load causes momentary increases in coolant temp, and thereby pressure.
How do I reduce the pressure in my cooling system?
