Re: bad smell and smoke
My first guess would be a leak in one of the heater hoses. There are two hoses that run from the water pump and intake manifold to your heater core. It is likely that one of them has developed a leak. It's a minor repair but should be done ASAP. Never let a coolant leak go on for very long at all.
