    coolant leaking from hose

    Hi, i just replaced the oil housing gasket and in order to get to a bolt i had to remove the coolant hose. once everything was finished turned the car on and everything was fine until i noticed coolant drops leaking on the belt? I tried to tighten the bolts of the hose even more but they just keep spinning with no end.... but the hose is on tight. I am guessing i should put some kind of sealant on any ideas why this could be happening?

    Thanks in advance.

    I'm thinking those bolts were overtorqued,
    and stripped the threads on the bolt or housing,
    or possibly both!
    You must follow torque specs, especially when dealing with aluminum.

    Might be a good idea to put this in the E90 forum.
