Is it normal for the lower radiator hose to have pressure; it feels like it wants to burst.?

It is not marking hot. I%26#039;ve changed termostat, radiator hose, other hose that has to do with coolant system, temp. sensor, flushed the radiator and changed water pump. Car was getting hot. Last thing i did was change water pump but lower rad. hose still has alot of pressure.|||Th radiator cap maintains pressure in the radiator, to prevent heating. A new radiator cap may be in order. Some hold pressure at 4 lbs or so. Water under pressure comes to a boil at a higher temp.
