Hi yes if it will not turn over then. Then yes you will be looking at engine more than likely.
If it is coolant will probally have a head gasket issue. If oil could be head gasket but with oil these cars are known for the oil seperator to freeze and will cause that kind of problem you are having and can also ruin the engine. Its a very common problem with the oil seperator. Yes you still can ask questions on this issue not a problem. I will then answer as info request. Or if I hit answer just dont hit accept again. And reply back again as needed. Thanks mike
