I was going to recommend checking this as well. Check that overflow bottle and make sure the leak isn't coming from there.

It comes out of the front of the intake and goes to the top of the water pump . That is probably the most overlooked hose . Lot of people don't know about it , and after they see it they don't want to know about it anymore . I would recommend if your going to do the thermostat , tear into it far enough and do the bypass hose while your there . Any more questions feel free to ask . Tom
Thats some good advice right there, that lil bypass hose will cause ya to lose your religion lol

Default coolant leak

Had the same problem. Only at night would I get a leak. It turned out to be the assembly that the upper hose connects to . There is only a O ring not a gasket preventing leaks. I had to take a picture to show the dealer where the coolant was comming from. It would never leak up pressure or when it was hot,just after a cool night. After it heated up I would never have a problem during the day... Good Luck Mike 2004 5.7 1500 ram

After I "burped" the system a few times, the level has evened out 1/4" below the cold fill line and hasnt moved in a week. No leaks either. I think maybe a little air was left in there.

Tell me about it!!!!! I had that problem with my Jeep, and for as many times as I popped the hood on that thing to check it out before a long trip, didn't notice it had come loose! That made me feel like the biggest idiot, running the heater in the Louisiana summer just to draw enough heat from the block to make it home only to find that darn thing was the culprit!

Hey mikeahern,

I'm having that exact issue myself on my 04 Ram. How did they fix this? A new o-ring? How much would I expect to pay to have this fixed? Any help is appreciated.

Thanks, 04SportHemi

This is a very good possibility. The 3.7/4.7 family of engines are notorious for trapping air and it can be a real bear to get out of you don't have a vacuum lift pump.
