Look carefully to see exactly where the leak is coming from. Could be the hose is going bad, could be that the reservoir has a crack. The system, at normal operating temperatures, does not continue to build pressure. Once the system is at a certain pressure at a certain temperature, then it stays at that pressure unless the temperature rises. Are your temperatures normal (assuming the coolant level is adequate) ?? If the temps are normal, it ain't a "pressure" issue, it is a straightforward leak. Find and fix .....

You most likely need a new reservoir tank. Common problem for the plastic to crack at the hose connector. Don’t try to fix with epoxy as that is a temporary fix at best. (Your call)
Gene Gulley (forum sponsor) has good prices on these. (50 bucks or so I believe – I haven’t priced one lately)
Install new rubber hoses when replacing the tank. The old hoses may be too stiff due to age.
