Hi fleaj5,
Sometimes leaks don't occur till the temp increases up and pressure builds up. For radiator top tank to leak, if you look carefully, you would notice the leak.
If the level is below the leaking area, it would be less noticeable. Topping up with coolant is not sufficient, as air could be trapped and when air gets to the top tank, the level decreases, thus no leak.
