I have a 2008 dodge 3500 with the 6.7 cummins. Recently I have developed what looks like a water leak. I get a small puddle just beside my right front tire. It looks like it is water as it does. It smell and dries by the morning. Weird thing is I am not running my a/c. But I do have my defrost on. I have read about a common water lump leak that this motor has but it doesn't look like coolant leaking?. I just checked my coolant reservoir and it is low but I just got home an hour ago and the rad hose is still warm. Any help would be great.
