All good advice.
I had a stuck T-stat that did the exact thing on a jeep a few years back....I walked away from it leaving it idling while spotting some one (Paragon)...and the radiator blew up.
I'd check the T-stat first, as blowing up the radiator is sudden, and worse than some of the other items, and a cheap fix if done before hand.
