Antifreeze/Coolant
Water and antifreeze mixture. The antifreeze has additives that help prevent corrosion.
Antifreeze is a substance such as glycol which is used to lower the freezing point of water, and is used as an additive in the radiators of motorcars.
Stop your cat from licking radiators IMMEDIATELY!!! Antifreeze used in radiators is not just poisonous, but deadly to cats even in small amounts. Unfortunately antifreeze also taste great to them. Please stop your cat immediately and consult a vet.
Eethylene Glycol
antifreeze antifreeze a fifty fifty micture of water and antifrez is best
So that the water used as coolant in most car radiators does not freeze overnight. If it does then, because ice expands as it freezes and melts, it can crack the engine block. The antifreeze lowers the freezing point of the coolant and reduces the risk. The more antifreeze, the less risk of freezing. But too much and it will boil when the car is running. Additives in antifreeze also reduces corrosion and raises the boiling point.
Propylene glycol used to be in vehicle antifreeze.
Yes 50/50 antifreeze is the most recommend antifreeze from most vehicle manufacturers.
In early cars (before 1930s), grain alcohol (cheap whiskey) mixed with water (or sometimes lamp alcohol mixed with water) was sometimes used as radiator antifreeze. Also sometimes radiators would simply be drained every night during cold weather to prevent freezing, and refilled with plain water before the vehicle was to be used again.
Most commonly it is a mixture of ethylene glycol. Each manufacturer uses their own dyes and anti-rust additives to the recipe.
antifreeze keeps your car from overheating, it flows thru your radiator hose, without it your motor would blow
