    All of that is working fine. My fan is coming on, thermostat is working, no leaks, brand spankin new radiator, everything. Could you explain what it means to have a blocked radiator core, and what the symptoms are?

First look for signs of coolant leakage at the water pump, radiator hoses, thermostat, transmission coolant lines, and intake gasket. If you're leaking at the water pump replace it. If you have no coolant loss check to see if your coolant fan is coming on. If all is fine then you probably have a faulty thermostat. If it still overheats you may have a blocked radiator core.

How much and what kinda oil for 2000 Durango v8

Five quarts of oil and if you have more than 75,000 miles on it use the High Mileage oil. If you live in a hot climate like me I use 10w40. Colder climates you might want to use 10w30.

I have a 97 Chevy Lumina. It has 276,*** miles on it. I bought it used 4 months ago. It was running excellent then the service engine soon light, low coolant light, and change oil soon light started coming...

The fact that the oil was low would not be from the oil pump, but from wear in the engine. If it is not smoking when you start it or as you drive, you can probably keep it running by just keeping the oil level checked at each fuel fill-up. As for the car shutting off, you didn't say if the engine seized or got real hot. A low oil pressure problem should have triggered a warning light before the problem got to the point where you lost the engine.

If the car ran after you added the oil, you got lucky and need to always check it.

I would like to know the posible causes of engine running hot.

was the engine overheating before this repair? and again do u have bubbles in the coolant tank when the engine is running?, this is best checked when the engine is 1st started. I ask because I think u may have a leaking cylinder head gasket, this would account for the overheating still occurring.
