Most antifreeze has a chemical that freezes at a very lower temp than plain water.
It changes the freezing and boiling point.
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.
A 50/50 mixture of water and coolant/antifreeze is highly recommended to avoid freezing and/or rusting within the radiator.
If you mean the water in your radiator, don't drive your vehicle until it thaws or your engine will overheat because no coolant will be flowing through it. You should keep 50% antifreeze and 50% distilled water in your car radiator at all times. (maybe slightly more antifreeze in cold winter weather) Water in the radiator won't freeze with antifreeze mixed with it.
The purpose of antifreeze in cars is to keep the engine from freezing in cold weather.
Antifreeze is not made out of any part of the pig. Antifreeze is a combination of chemicals used to keep your engine's liquids from freezing. It works by lowering the freezing point of liquids.
enough to keep it from freezing.
This is used to keep the motor from overheating and from freezing. Thus the name "antifreeze" and "coolant".
What I do is put half antifreeze and half water in to the radiator and keep putting more radiator fluid tell you see it in the neck of the radiator and put some radiator fluid in the coolant reservoir tank too.
If your use anything more concentrated than about half anitfreeze and half water, the radiator water will freeze at a considerably warmer temperature. There will be less protection. Also, antifreeze actually helps keep your car running cooler in summer. If you use straight antifreeze, the car will "boil over" at a much lower temperature. There will be less protection.
Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.
The benefits of antifreeze is it helps keep your engine from overheating by keeping the water cooler in hot weather and from freezing in the winter so it can circulate and cool the engine. The hazards are it is extremely poisonous, especially to animals.
