So I know the answer to this might be "Headgasket" but I wanted to ask anyways. I have a 2003 Dodge Ram 2500 with the 5.7 hemi. I was towing with it one day and it overheated badly. Let it cool and filled it back up and nursed it back home. Ever since I've been loosing coolant out the overflow. I've replaced the thermostat, radiator cap and the water pump. Before replacing the water pump I noticed the temp guage rise up to almost "H" and then drop back down and fluctuate around normal. After replacing the water pump I saw a noticeable improvement in Temps having it go to about a little under normal and have it stay there. It did go up about 3/4 way up the guage and drop back down an have it stay steady. However it still pushes coolant out the overflow. When it does its always the same amount each time I top it off. My thinking is that if it is a headgasket, it would push all the coolant out and not a set amount each time. BTW this truck has the horrible coolant setup where the overflow tank is incorporated into the pressurized cooling system. Any help would be greatly appreciated.
