273 Coolant leak help

Got it all back together finally. Car has sat more than its been driven this summer.
A few drips but nothing drastic. One thing I did was put heatshrink on the hose clamps to try and give it a "cleaner" look. But it seems to me anyway that it could be part of the reason for the drips(see pic of hump hose)

I've got heatshrink on my hose clamps also. Never a problem with leaks & I really like the cleaner look...
