You know me and my 34-yr old Chevy. the latest problem is a minute (small) coolant leak somewhere near the base of the radiator. The thing that bothers me is that it does not leak everyday that I run the engine, more like once in every three or four days that I notice a small puddle under the radiator. The clamp on the upper hose at the rad was loose so I tightened it and I thought that would solve the problem, BUT, it still leaks occasionally.

Anyone has any idea why?
