It has a much lower freezing point than water. if the coolant freezes it expands cauing pressure damage or even leaks. It also contains anti corrosion chemicals to prevent rust inside the engine.

Yes.If you have no antifreeze in the radiator or engine,sometimes it will freeze.Usually a freeze plug in the engine will pop out before any major damage is done. Sometimes the block will crack,or the radiator will crack or burst if no anti freeze is in the system.
If the antifreeze/coolant level in the radiator gets low enough, the engine will over heat. If the engine overheats enough, it could warp the intake manifold requiring a very expensive repair. Do yourelf a favor and get theleak repaired.
antifreeze does not enter the engine at any time. locate and follow your radiator hoses and follow then and check for cracks or punctures.
Because there is antifreeze int he system and it takes a while to burn through. Also replace the bottom hose too. <> If it smokes from under the hood, It has antifreeze on the engine exterior, You can wash it off. Or just drive it and it will burn off. If it smokes from the exhaust, There is engine damage.
look for antifreeze coming out of the radiator as the engine warms up after a cold start.
To the overflow tank and if the radiator has a cap,you will need to fill it with the engine cold.
if you run your engine without antifreeze your car will overheat and ruin the engine.
Into the engine's radiator at the front of the engine compartment ; see the link below to a video tutorial .
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.
