    Default Inboard Cooling Question

    So I'm getting the engine ready for use today, and I notice that there is something inside the coolant hose right where I have the arrow drawn on the attached image.
    5.7 Kodiak carb. Before I drain and see what it is, any ideas? Feels metallic through the hose when I squeeze.

    Could it be like a spring ? So the hose does n,'t collapse.

    Well that would certainly make sense. Is it common for guys to have something like that in the suction side? I'm hoping someone knows for sure so I don't have to drain it.

    You should be able to put pressure on the hose and feel the spaces in the spring and the ridges where the wire is.

    Yes, very common. Aifboats use this type of hose or we hardline the hoses to prevent them from collapsing on the big blocks.

    Call Wooldridge or motor builder to clarify before tearing it apart.

    Yes it's a spring. Most use the wire reinforced hose instead of a spring these day but the spring works fine as well on the suction side.

    Thanks gents
    sure enough, it's a spring. Now that you guys brought it up, totally makes sense to have one in there.
