It should be ok as there is nothing too terrible in the coolant. Excess antifreeze will just overflow. Try and get some out. Antifreeze can cause paint issues if the concentration is high enough...RR
Doubtful !... The antifreeze is added to the radiator - to keep the water above freezing point. There is no way of the engine knowing how much antifreeze is circulating.
Keep the engine coolant or antifreeze from rising above its operational temperature.
In the event that it over-heats and seizes, then yes. If your cooling fliud is plain water, and the engine hasn't frozen, then lack of antifreeze should not affect things in the short term. It is obviously desirable to have antifreeze in cold weather so the the enginge doesn't freeze. As above, if there is no cooling fluid at all, the engine will over-heat and sieze up.

On my 350ci chevy, it is above/beside the starter on the engine block. BE CAREFUL or you will get a face full of antifreeze!
You could have to much coolant in your reservoir tank. If it is above the fill line it will come out of the overflow. Some of this overflow could get onto your engine and be causing the odor your smelling. Good Luck! It could be a leak, and the anti-freeze "steam" can only enter the car when stopped. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info
it is on top front of engine on left side,belt side. above water pump on engine. there is a bleeder cap on it. the back side bleeder is to relieve fuel pressure.
Above the master cylinder, below the brake fluid reservoir lid.
steering fluid reservoirunder hood, passenger side, above serpentine belt.
Freeze Plugs could be bad. Not a water pump, the water pump is located on the front of the engine.
Just in the case of an emergency ( and if the temperature is above freezing ) Straight water has no corrosion protection for your engine cooling system like a 50 / 50 mixture of antifreeze and preferably distilled water ( although the corrosion protection of antifreeze does " wear out " )
Saturns are not equipped with a "oil" reservior. The only reserviors located under the hood should be as follows. Lower left corner is your wash fluid Just above that is your antifreeze/coolant. Upper left corner on the engine is Power steering fluid. Upper right corner on the firewall is your Brake fluid Upper right corner to the right of your brake fluid is the Clutch, if equipped with a manual transmission.
