Antifreeze contains chemicals which have a much lower freeze temperature than just water. That resists freezing when the vehicle is not being operated. During operation, when coolant cycles through the system, heat from the engine is transferred to the coolant... this heats up the coolant... that heat is then exchanged to the air which blows through the radiator fins.
It stops your car from freezing and not starting up in cold weather
During Winter or whenever it is cold to lower the freezing point of the water in your car radiator. :] F
they do this to lower the freezing temp of the water so then it wouldd have to drop below 0 degrees.
increases, and lowers
Putting 100% "straight" antifreeze in your car's radiator will expose the cooling system to freezing at a much higher temperature than would the appropriate and recommended mix of roughly 50/50 antifreeze and water. Antifreeze works best WITH water.
The antifreeze provides corrosion protection until the corrosion package is " used up " and it raises the boiling point and lowers the freezing point of the water
We always renew the antifreeze in our car before winter.
Antifreeze keeps your coolant from freezing. It keeps your coolant more "fluid".
Yes
This has got two properties in general. For cooling only, then you need only water. The problem with only water is when the car stand still with engine off in a cold environment. Water will eventually freeze, thus expand. This expansion will rupture the radiator and engine will quickly overheat because water runs out. Only water might also corrode the inside surface of the radiator. Most antifreeze liquids today offer frost-protection and corrosion-protection. The antifreeze liquid just lowers the waters temperature-point of freezing. Even when freezing (to a slurry) it does not form solid ice that can rupture the radiator.
the antifreeze runs through all your water lines in your car . . . . you put it in your water tank or radiator
No. The antifreeze has to be mixed with the water before the water freezes.
