Cooling Problem Diagnostics
This problem began this morning. As I was driving into work, I noticed that I wasn't getting any heat at all from my vents, even though the engine was warmed up. As I arrived at work, I noticed that the engine was running very hot on the temp gauge.
The ride to work is short, so there wasn't that much risk. I figured maybe there was some ice in the radiator or that the coolant level was low. I topped off the coolant with some 50/50 I keep handy and checked the radiator. Sure enough, there was a bit of coolant-ice on the driver's side of it.
I drove home and encountered the exact same problem. Engine getting hot, no heat from the vents.
Arriving home, I checked the radiator again. There was still ice on it, and there was a small drip coming from where the ice had formed. I concluded that no warm fluid was running to the radiator (otherwise it would have melted).
Based on these events, my first and worst conclusion is that it is the water pump. I'm not getting any flow to the radiator or the heating core, both of which are provided by the pump. The radiator will need to be replaced eventually anyway (its leaking after all), but the pump is going to keep the truck from being usable for the immediate future.
Does this seem like the correct conclusion?

That's true about the mixture. I'm in the process of moving to a colder climate, so these things will start coming up more often. I'll try running the engine once the day gets warmer, but that hasn't quite answered the flow problem.
