yes, all the Saturn DOHC motors are interference engines.
As you listed this in the Saturn Vue category I will assume you have a Saturn Vue. The 2004 and up Saturn Vue engine was manufactured by Honda and it is an interference engine. The belt and water pump must be replaced every 100,000 miles. All other years used a GM V6 that was also an interference engine. The 4 cylinder Saturn Vue did not use a belt but had a chain.
No, from talking to repair shops and a dealer about my own Saturn Ion-2, I have learned that it does in fact use an interference design.
yes you are screwed if the chain breaks
