My 2001 C70 is leaking coolant from the overflow hose at the coolant reservoir. I tried replacing the clamp that holds the hose on but there is a nipple of some sort in the end of the hose that does not allow the hose to seal tightly on the reservoir. Does anyone have any ideas about stopping the leak without replacing the hose, which looks fine.

Well after I replaced the original clamp with a wormdrive clamp I ran the enigne to warm it up and circulate the coolant, I looked for leaks between the reservoir and hose connection and noticed bubbling around the hose connection.

Do you have a picture of the end of the hose? Are you sure the reservoir isn't leaking or damaged? If the clamp is good then it may need the hosed replaced if the tank is in good working order.

Update: I found a small crack in the bottom of the reservoir, I replaced the reservoir and hoses, I went with OEM hoses from ipd.
