With the 1.3 the higher pressure is going to circulate coolant coolant faster, so it will cool the motor better at higher speeds. … Higher cooling system pressure raises the boiling point of coolant to reduce the risk of overheating. as the pressure and temp rise. Below are functions of radiator caps in automotive engines: A radiator pressure cap keeps the system pressure at 16 PSI, which avoids the coolant from boiling off even when it gets hotter considerably. High-performance engines also create more heat. Coolant that is boiling cannot transfer as much heat and overheating is likely to occur. This allows the coolant to reach much higher temperatures without boiling away. Higher pressure caps can boost the boiling point even more. A faulty radiator cap can cause your car to boil-over at a lower temperature, but is an easy and inexpensive DIY repair. So, pressurized cooling systems help prevent overheating and coolant loss. So you should be good to around 240 degrees depending on coolant boiling point. At sea level, water boils at 212 degrees. Stant 10231 Radiator Cap - 16 PSI Vented. The manufacturer told us that 20 psi would be no problem...it appears they were wrong. My current radiator cap is a 13 psi cap and im looking at replacements that are either a 16 or 18 psi. x 3/4" deep necks unless otherwise noted. x 3/4" deep necks unless otherwise noted. Each lb. The cap has a small disc at the bottom of the cap that is a vacuum valve. It is designed to add pressure to the cooling system and increase the boiling point like grandma's pressure cooker. Ideally, car cooling systems should maintain a pressure of around 13 to 16 PSI. Radiator caps hold pressures between 6-16 PSI for most automotive systems. A radiator cap keeps the cooling system pressured which raises the boiling point. ... raising the pressure at which your radiator cap releases is raising the boiling point of the fluid in your cooling system. This means that a cap rated at 13 lbs. Allstar Radiator Cap Small Stant 16 PSI ALL30124. cap gives at least a 250 F boiling point. How does an increase in pressure affect the coolant is boiling point? ACDelco RC85 GM Original Equipment 15 P.S.I. Recovery system caps allow coolant to exit the cooling system into an overflow or recovery bottle as coolant heats and expands. It is designed to add pressure to the cooling system and increase the boiling point like grandma's pressure cooker. Otherwise I can't see any real reason they didn't use a more standard 15 psi cap. In all actuality, the formula is: for every 2 PSI increase (at sea level) you increase the boiling point 1* above 212*. This is because for every pound of spring pressure, the boiling point is increased by 3° F. Water boils at 212° F, increasing the pressure in a closed system increases the boiling point. By adding 16 pounds of pressure to the system you will raise the boiling point … I don't remember ever seeing a 16 pound radiator cap before (really high PSI in my mind), I was thinking 8-10 would be more appropriate. at atmospheric pressure, if exposed to 15 psi (a common radiator pressure cap), the boiling point will now be 45°F. I have a buddy who's car would over heat in the texas weather. ... Hi Luigi, 16 psi is 16lbs, the PSI is "Pounds per square inch" Hence a 16lb cap. Ford might have been afraid that 16 psi would burst the heater core or maybe the radiator(?). That vacuum valve hangs down in the open position until the cap is subjected to rapid expansion of coolant or steam, which closes the valve in a sealed position. At that point, the system is pressurized and helps control overheating and enhances system efficiency. The radiator cap maintains system pressure to 16 pounds per square inch (psi) on most vehicles. High-performance caps range from 19 – 32 psi. If your gaskets, hoses, radiator are in great shape, that pressure should keep it from puking out coolant when shut down hot. A faulty radiator cap can result in engine overheating, loss of coolant or major engine damage. So the over-simplified answer to the tech quiz is that, yes, a higher pressure radiator cap can help prevent overheating. Whereas water boils at around 212°F. Higher cooling system pressure raises the boiling point of coolant to reduce the risk of overheating. Radiator Cap. The radiator cap controls this expansion and provides constant pressure on the system. But anyways, you should be fine with either the .9 or the 1.3 cap. At higher elevations the boiling temperatures are all lower since atmospheric pressure is lower up here. Radiator Caps are manufactured using either metal or plastic design depending on the vehicle manufacturer’s specifications. Which one do i need? This protects the system from boiling over at the top of the operating temperature range. For every pound of pressure exerted on the coolant in the system, the static boiling point of the coolant is increased by 3 degrees F. Keeping coolant in a liquid form allows the fluid to do it's job transferring heat to the radiator to be dissipated. I'd suggest running a normal overflow recovery cap and tank and make sure the radiator is full when up to operating temp, fill the overflow tank to about 1/3 with coolant and call 'er good. The cooling system uses pressure to further raise the boiling point of the coolant. The system is pressurized to increase the boiling point of the coolant, by doing so you allow the engine to run hotter without boiling off the coolant thru the overflow. of pressure raises the boiling point about 2 degrees, over 2 at 212 and a little less per lb.
