    These are actually very good points. The inner layers of the hose could've partially peeled away or collapsing, causing intermittent blockages. It's rare, but it does happen.

    It is a common problem with ICE lower radiator hoses if the radiator is partially blocked.
    The manufacturer adds a wire "spring" inside the hose to stop it collapsing, but if the cooling system has been neglected, that steel wire rusts until it breaks, then the hose collapses under load .....
