Sounds like a ground issue - (not sure about the bubbling sound). Your Negative terminal looks pretty corroded. Take it off clean it up and secure it nice and tight then see if it happens again.
Clean your battery terminals and cable clamps. Those are corroded, especially the positive terminal.So, I went out and took a look and some pics for ya.
The coolant level looks fine in the overflow reservoir. The radiator cap was on nice and tight (though I think I'll get a replacement just in case).
Battery terminals had a bit of corrosion on them. The battery is practically new (less than 6mos old) and the guy at Advance put it in for me. Put the anti-corrosion stuff on the terminals and all.

Just to be safe I'm taking it to the local shop for a coolant flush. $70 and they flush the heater core as well.Hows the oil look? (any white or brown snot?)
How's the antifreeze look (any oil in it?)
Tranny fluid smell and color good? Or smells burnt and not so bright?)
That's a great post - thanks for the help!You've got a big air pocket in the cooling system and and a thermostat that may not be opening properly at operating temp. try taking the radiator cap off when cold, fill with water, turn heater temp to hot and start it up. Let the engine warm up and watch the water level in radiator and see if it will purge the air pocket. Hopefully the water level will drop and then add more water. A squeeze on the upper radiator hose and you'll know if it's dry. Check your gauge, put your cap on and then shut off. Double check fluid level in overflow reservoir at hot line.
Just a note, as it heats up it will want to puke water as it expands until the air gets expelled. It should take about 15 Min or so.
Some vehicles are very easy to get the air out and others it's only possible by unscrewing a relief port at the high point.
The positive battery needs cleaning to remove corrosion. Take hot water and pour it on the corroded terminal and it will disolve it. Then pull the battery terminal and clean post and terminal. Also you should take cable to terminal connection apart and make sure it's clean with wire brush and is tight.
My 02 Dakota 4.7 blew a head gasket. Never showed liquid mix in the oil or coolant but rather in the fact it would overpressurize the cooling system and blow coolant out of the overflow tank rather explosively. Took me a couple of these incidents before I figured out what was happening.Sure hope you're wrong!
Good point- that happens also.My 02 Dakota 4.7 blew a head gasket.

Well, it's already at the shop. So, I'm waiting to hear back from them. Should hear from them in an hour or two. I'll check when I get down to pick it up.You might get a preview of the head condition by looking at engine oil and antifreeze -- if it's not on the ground, or traces in pockets on top of engine, wet under the heater core, etc -then it will be showing up in the oil or oil in the antifreeze. Gotta go somewhere IF it not just an old air pocket that has been trapped a long while.
Ask the shop specifically for a block check. They can do it before tearing it down and you spending any more money. It uses a blue liquid that will turn yellow when combustion gases are present in the cooling system and will detect even the smallest combustion leaks.I just called the shop and asked if they could do a head check. He said that when they get it torn down and repressureize, he'll be able to tell if it's a head gasket issue. He think it's just a thermostat issue at the moment - fingers crossed it's just the thermostat!
Whether or not it's a head gasket, the fluid needs flushed anyway. I've had it for two years and it's not been done since I've had it. I also don't know how long it's been since it was done before I had it. So it's just something that needs done regardless.Ask the shop specifically for a block check.

A blown head gasket or cracked head won’t always put oil in the coolant or coolant in the oil. The coolant maybe going out the tailpipe.
