At the risk of asking the obvious, are you using silicone hose clamps, or
regular hose clamps?
Here's a hint--silicone hose is extremely fragile and regular hose clamps
will slice right into the hoses, causing leaks. If you have silicone hoses, you
MUST use proper clamps (called T-bolt clamps) such as these:

Note the very different construction from a standard hose clamp.
The other alternative is a liner clamp, which is basically a standard-style
hose clamp with a liner inside to prevent the clamp from eating the hose:

Because silicone hoses expand and contract much more than rubber hoses, an
alternative designed to cover a wide temperature spread is a spring-loaded
T-clamp.

The nut tightens against a spring, which allows the hose to expand and
contract as needed to ensure a good seal with silicone hoses--which otherwise don't
particularly like to seal.
What a pain in the ass.
There's not enough money in the world to get me to put silicone hoses on any
car I own. Heavy duty rubber hoses work great and don't deliver the kind of
headaches you are suffering with now....
