my low coolant warning came on today, but i didn't check it. later as i left work, i popped open the hood to see what was going on. there was coolant splattered all over the place. since the bmw indy i go to was on the way home, i decided to stop by. the service advisor seems to think it's coming from the hose, and the coolant got splattered due to air flow when driving and from the fan. btw... the car has been running at normal temp before and after.

anyway, i took some pictures of the hose. it bulges out after the clamp, but then shrinks down to normal. is this is hose bad?

and i'm guessing, that it's not too hard to replace yourself? wait til the car is totally cold, remove/replace, lose so coolant in the process, add some coolant back in, and bleed?
