I have a 2005 m7 and the other day the engine light flashed on me for overheating. So it appeared to me that one of the hoses slipped off the bottle and was leaking coolant, I fixed this with a hose clamp. So now when I ride it, it very slowly looses coolant, it does not appear to leak in the garage. I looked at the coolant bottle and it seems like the filler neck is warped (like an oval), would this cause the coolant to leak? Also when I open the coolant bottle with the sled hot there is no pressure under the cap, Should there be?
Thanks for any responses.
