Water pressure

[971of1000]

Does anyone know what kind of pressure the coolant system in our cars sees at idle? at wot?

coolant pressure is dictated by the cap, mines 13lbs. hot or cold will be the only variation rpms wont affect it, unless you have too little pressure then the water pump can cavitate.
