Been to the online parts illustrations but I just can't determine what the part# is on this coolant hose. The vehicle is a 2008 Mercedes 320GL. The hose is the top one in the picture with the red X on it. Anybody know what the part# is for this ? Come on guys, no one knows the part# It's not a matter of me being too lazy to go to the dealer. The nearest dealer is 180 miles away and I'm not too fond of the idea of making that drive with a leaking hose. Even then the dealer is in Anchorage Alaska so the odds of them having a part on hand is not a dice roll I'm anxious to take. Thanks, Will
