Why does it smell like engine is hot?

Have 2010 Sebring Limited. Just guessing here. A loose hose lodged against motor (or hot part of other component) and is burning rubber. Oil leaking out somewhere and burning (would be slight smoke look when lifting hood). Anti-freeze leak and smelling. Know that vents "bleed" air when off, but may give you a clue as to smell. NOTE: years ago Ieft oil cap off and ran car. Oil leaked all over engine and components. Oil burned or smoked when hot.
