Any worries about using silicone hoses?
 

I bought a red silicone hose kit that comes in 4 different sizes. I'm planning to replace most if not all of the rubber hoses in my engine bay with these red silicone ones. I swapped a couple already and they were a little loose so I just used metal clamps or zip ties to keep them on without falling off. By using silicone hoses instead of the factory rubber ones, do I have anything I should worry about or will they be ok?

I have them in my car. Just as long as they are clamped down tightly so they dont slip off you should be fine.
