Bubbling noise from engine area

I have a 2002 Durango 4 x 4 4.7L with 78,000 miles. Recently the car began overheating when I sat at the bus stop waiting for the kids. My brother changed out the thermostat after doing a pressure check to make sure there were no leaks. Yesterday I started the car and there is a bubbling/boiling noise coming from up front. Any ideas what it might be?
P.S. The overheating seems to have stopped, however I did notice my temperature gage going a little higher after driving for a while last week. I turned on the heat and it dropped back down.

Did your brother burp the engine? If not, here's how:
1: Park at a slight incline so that the upper radiator hose is the highest point.
2: Wait for the engine to cool down before opning the radiator cap.
3: Unscrew the orange-colored allen bolt where the hose meets the engine. Do not unscrew all the way just enough to be loose.
4: Turn on the engine and watch for the coolant flowing past the cap.
5: Slowly add coolant until you see it leaking from the allen bolt past the threads.
6: Tighten the allen nut and close off the rad cap. You have burped the D.

1) Raise up th efront of the D and put jack stands under the frame.
2) Get under the front of the D right below the rear of the front bumper.
3) You will see an opening where you can reach in and see a green connector. That's the e-fan connector.
4) Unplug the connector and run a dedicated line from the battery to the connector. Plus to plus, neg to neg.
If the e-fan kicks on with the direct feed, you have a problem somewhere between the fuses/relays and the e-fan. If it still doesn't spin, you need a new e-fan.
BTW, you can check for continuity from the connector as well. Use a volt meter or a test light to see if you're getting power to the connector by turning on the a/c or defroster to see if you're getting a reading. HTH
