I have a 02 4.7 dodge ram. I just replaced the thermostat housing, the reservoir, and checked to see if there was a head gasket problem. I have also had to change out the radiator cap a couple of times. There was nothing wrong. I notice that the antifreeze is coming from the overflow tube on the reservoir. Why would it have that much pressure.

 

You may have a clogged radiator. Especially (and I'm not saying you did) if you use the radiator stop leak in the truck. You may try flushing the system really good and see if that will clear it up. You can buy the kit at any local parts dealer. Did you just replace the thermostat housing or did you hopefully already change the thermostat too. I guess I'll just assume that's what you mean, that you've changed it. Try the flush and see what happens. They're relatively inexpensive.

Had a new radiator put on last summer.

 

what ever you do dont let it over heat youll smoke that motor....have u changed that t-stat? do you have too much freeze in the jug? and how are your hoses top and bottom?

 

Everything is good as of the hoses, changed the t-stat and watch the coolant every other day or add some to it. It doesn't get hot or anything, just blows my mind why its leaking out of the overflow tube. Its like it has a ton of pressure.

 

well that might be the ticket how about getting a pressure test done and see why it might be more technical than we think......
