    Today I noticed that the top radiator hose is collapsed. I just replaced it over Christmas break when it blew itself off the manifold and now it's collapsed. Why? Does this mean my thermostat is bad or what? When I replaced the hoses, I also replaced the thermostat. Any one know what caused it? Are there supposed to be springs in the top one like in the bottom one? Thanks for any help.

    I believe you need to replace your radiator cap.

    i would have to agree. If the cap isn't vented to overflow water to the overflow tank when it gets hot and expands it builds a lot of pressure, and not allowing water back in when it cools it will produce a vacuum in the system, which causes the hose to "implode". hehe. Should be simple.
