a coolant system should not have any open vent in it,

There`s a pressurised cap on the radiator of course,I think there should be a release valve in the header cap,but there isn`t onethere is still something not right,an airlock perhaps??Got home from DD,temp guage on about 80,switch off and the fan cuts in
How do you remove an airlock?Has anyone got a picture of there cap so I can compare?There is an allen bolt at the bottom of the rear cylinder which releases coolant when you undo it,but what`s the correct proceedure?
