04 V8 Cooling Issue

[Adt14195]

Just bought my LS last month. Loved it so far. Up until last week, I'd been losing coolant. My heat would go cold and engine temps would spike. I'd planned to just add coolant until I had the chance to get it properly looked at, but now the system isn't flowing at all. The reservoir is full and nothing but air at the thermostat. I'm guessing my leak got worse but I can't tell where it's coming from at the moment. The only evidence I've seen of a leak is dried coolant on the side of the degas bottle (reservoir). The lack of flow makes me think its the water pump, but
I'm not sure. Any help is appreciated.

Trust me, it's coming from everywhere.
You need to do this.

And this part is critical after you change all the parts.

Or, you could do it the correct way (and then only have to do it once).

BTW, removing the degas cap never lets air into the cooling system. Please don't remove the bleed screw just to open the cap. (I didn't watch the video much past that statement.)

Oops, well, maybe not then...the guy was a bit nutty...
