I am looking for guidance from any of you out there. On a road trip on our vacation in an 03 X5 4.6is with a 126K miles on the clock. We did a 11 hours across Colorado, Wyoming and half way across Montana. Car ran flawlessly.

Got to our daughters place in Big Sky on Friday evening. Car ran great, cruise on 80 all the way across WY and MT with AC on. Never got hot. Went to start it up next am and saw a puddle underneath. It was definitely coolant leaking from left side of engine. I drove it up on wheel ramps and cannot see much with out removing the aluminum engine pan cover. Start it and after a minute begins to leak again but stops after things have cooled down.

Since I am on the road I don't have tools to trouble shoot/repair this but from what I have read in the threads it is most likely a heater hose leak. Since it was a weekend no shops are open so I will have car towed to Bozeman MT. Anyone on the threads with a lead for a good mechanic shop in Bozeman? Any thing I can tell them that will help diagnos the problem and get me back on the road?

I have owned this car for 7-8 years and do a lot of the regular maintenance things myself so I know a little bit. Replaced the expansion tank on it already, done coolant flush a couple of times just to get rid of the old and put in new. Thanks in advance for any guidance.
