Hose leak should be visible upon inspection. Your local auto parts store will have the size if you tell them vehicle make, year, and model and engine size. You will need engine coolant as well to refill radiator.

Where are heater core hoses in 2003 dodge grand caravan?

You will find them under the hood.
Do you know what the heater core is? About the size of a hard-back book, it is a small radiator with engine coolant passing through it. It is located inside the heater case under the dash.
There are two hoses, an inlet line and a return line. Both same size, about 1 inch in diameter. Both hoses come from the engine and go up to the firewall behind the engine. Both hoses connect to the heater core right at the firewall, so there are hose clamps on the end of the hoses.
You can remove and replace the heater hoses right there under the hood, pretty easy too. But if you need to replace the heater core, that comes out from under the dash. Often there is a lot of work to get to the core, as there is a loot in the way.

No heat. blower ok. engine temp normal. Can not locate the heater hoses to check if both are hot. How do I get access to the hoses? Is there a diagram?

Without more specs re: engine size etc, I'd have to say look close at firewall between engine and cab for hoses /tubing going into passenger compartment through firewall.

I have a 2005 chevy malibu and need to know which port to recharge the system through. The lower port (located near the firewall) or the upper port (located near the upper left side of the radiator)?

You didn't mention your engine size but if you have the correct tool to charge the A/C system there are 2 different sizes and the connector that you use to charge it with will only fit on the correct one as they are 2 different sizes. The 2 different connectors of valves like I said are different sizes. The one you use will be the smaller of the 2 valves. The hose itself is larger but the port you fill up is the smalled one out of the 2. The hose will only fit on the 1 that fills it.

It is on the front of the engine, follow the upper radiator hose to the engine block. On a 4 cylinder engine it's located on the front of the engine block. On the 6 cylinder engine, it's located near the front of the intake manifold. There should be three bolts, remove and thermostat should be underneath. pay attention to the way it was installed.

Just had radiator replaced, leak has developed around housing/gasket of hose running to passenger side just to side of engine and slightly behind. My mechanic doesn't know what the part is we are looking...

is it actually on the engine? I ask because you say it is to the passenger side and just behind the engine, that makes me think it is a heater hose, the heater hoses go from the water pump to the heater core which is located on the passenger side, the difference between heater hoses and radiator hoses is the size and of course location, heater hoses are generally about 1/2 inch to 1 inch, with radiator hoses being between 1 3/4 and 3 inches
