My radiator cap is smoking and coolant begins to leak from the hoses. The temperature gauge starts to rise after this happens after the cars running for about 5 minutes. I replaced the hoses, radiator cap, and even the thermostat, but to no avail.
Is there no water circulating? If so, could this be a water pump problem? Thank you.

I hate to be the bearer of bad tidings, but it sounds like you have a headgasket out or a cracked head. With radiator full. If you run the cold motor for a few minuets, do you get excessive pressure at the radiator cap? If so, you have a head problem. Do you get any white smoke out the tailpipe? Please advise.

Yes, smoke increases out of the tailpipe. Pressure does indeed increase at the radiator cap.
I put anti-freeze in the night before. The next morning I discovered the smoke radiating from the cap and antifreeze was everywhere. I come to find the radiator hose hanging off.
That led me to replace the hoses and thermostat, but the problem is persisting and I am trying to sell.

Yes, Ihave to believe you have a head or gasket problem especially if you're blowing hoses. A normal cooling system runs around 12 to 14lbs pressure, but a compression leak can boost it up to 100lbs or more.

Thanks James. As a mechanic, what do you suppose the final cost would be to replace head gasket on Durango?

How much $ is always a toughy. Flat rate shows 8 to 10 hours for doing both sides. Not knowing what took the gasket out or cracked the head, I can only guess, but it would be foolish to do only one side. To do only one side shows a labor reduction of only 1 1/2 hours. Parts would be a "headset" which is all the gaskets for the top end of the motor, about $100. If one of the heads is cracked, you'll need a replacement. Used would be about $75-$100. Labor is the biggie, and that depends on where you take it, and how hungry they are. Dealerships are never hungry. I would highly recommend shopping around, get recommendations for other people about a good shop. You can tell which cylinder(s) are leaking by letting it sit overnight. The next day, disable the ignition so it doesn't start and crank the motor a few times then pull the plugs. You should see coolant on the plug tips. Hope this has helped.
