My 2003 Dodge Caravan is over-heating.
I've changed the thermostat but this hasn't solved the problem. The upper hose on the radiator is warm (and appears to soften).
What would be the next thing to check/replace?

It wouldn't be hot if coolant wasn't running through it. So the question is: Is enough coolant flowing? That would be a water pump issue. Or, are the radiator fans not doing a good enough job. That would be a fan or fan relay problem. See this article on Chrysler fan relays
