Engine hot

dodge sport van, 155k, newly rebuilt transmission, new radiator last week after it overheated. drove it today and it got hot and the needle went to hot and the engine oil light came on. now what?

Now you get someone to check the compression to find out whether the engine is wrecked or not.

Who diagnosed and replaced the radiator? I’m not asking b/c I’m skeptical that it was needed - just b/c at the moment that would be my first stop.
