Why would pure antifreeze freeze in the plastic bottle beside the radiator and the radiator itself in cold weather while there is no leakage?

Actually, this is to be expected when one considers that ethylene glycol, the principal component of most antifreezes, freezes at 8 degrees above zero, Fahrenheit. It is only when water is added that the freezing point is depressed. The freezing point of an ethylene glycol and water mixture drops rapidly as the concentration of glycol is increased to a mixture of about 60% antifreeze and 40% water. Around that point, an abrupt turnabout occurs, and as more antifreeze is added, the freezing point rises almost as fast as it had previously dropped. It's clearly a case of what you don't know can hurt you, but I have never seen an antifreeze container with an explanatory note to this effect. It must have leakage somewhere. When it gets cold the antifreeze contracs. That is why there is a bottle next to the radiator that has two marks COLD and hot. the level should be in between these. If it is not and way off then you have a leak somewhere. Leak may be small, may be in the hadgasket (no good), look under the car to see if any green or colr fluid is under overnite. Did you unscrew the radiator cap and forget to tighten it roccetly?

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.

Yes, you can add antifreeze / coolant to a car without flushing the radiator. It's best to use the same type that's already in your car / truck - conventional or long-life. Antifreeze / Coolant comes in 'Full Strength' which needs to be mixed with distilled water (usually 50/50 for mild weather regions, and more antifreeze 70/30 for really cold weather regions.) Also available is pre-mixed 50/50 antifreeze. PEAK Antifreeze & Coolant protects from -84 degrees to 276 degrees Fahrenheit when mixed 70/30. If it's been 2-3 years since a flush & fill for conventional antifreeze / radiator fluid, or 5 years for 'long life' antifreeze, it's likely time for a flush & fill.

Antifreeze is not car specific as much as it is weather specific. look for the antifreeze that will work with your coldest weather to do exactly what it does which is prevents freezing. make sure to mix it 50/50 with water by dividing your radiator capacity in 1/2. many companies like prestone make premixed antifreeze as well I'm sorry but antifreeze is made for specific cars use what is compatible with your car or truck It uses regular Green.

Flush and clean your heater radiator wich is located inside the car. No that is incorrect. All you have to do is add antifreeze to your reservoir keep adding it till you get heat. You may have to let your car sit awhile on the on position. I know this is your problem because it works in the warmer weather. Unless your thermostat is stuck and the heater was just blowing air off your motor but I doubt that. Make sure you add enough antifreeze though. You never add when your vehicle is hot and if you add in radiator make sure car is on. If you have to much water in it to add antifreeze there is a screw under radiator to release water from radiator. GOODLUCK

The purpose of antifreeze in cars is to keep the engine from freezing in cold weather.

Place a pan below the vehicle to catch the draining coolant. Remove the surge tank cap. Disconnect the lower radiator hose. Drain the coolant. Reconnect the lower radiator hose. Fill the cooling system through the surge tank with a mixture of ethylene glycol antifreeze and water. The mixture must be at least 50 percent antifreeze, but not more than 60 percent antifreeze for cold weather operation.

depending if you live in mainly cold or hot weather area, cold weather-- use a 50-50 dexcool [orange liquid] straight in backup tank and 50% antifreeze/50% water in radiator, do not add water to backup tank. Hot weather-- [my recommendation] use a 50-50 dexcool [orange liquid] straight in backup tank [no water], and 20% antifreeze/80% water plus add liquid called waterwetter [pink liquid] to radiator, this will greatly keep engine running cooler by almost 15-20 degrees

Assuming you still have some form of coolant (water) in your radiator then the coolant will freeze when the weather is cold enough, coolant expands when it freezes, this may cause permanent damage to your engine, such as split pipe's, burst radiator, cracked engine block

Antifreeze does 2 things. First it protects your engine when the outside temperature is below freezing and the vehicle is not running. If the coolant freezes it could crack your engine block requiring a new engine. Caution: 100% antifreeze will also freeze up if it gets too cold. For best results you have to mix antifreeze and water. Check the antifreeze container for correct mixture. Antifreeze also has other things in it that keeps the water pump in good shape, prevents corrosion of the the radiator and helps transfer heat out of the engine. You need it even in hot weather.

Plastic patio benches are more weather resistant than wooden ones. Wooden can rot. Plastic won't deteriorate in any weather.

It stops your car from freezing and not starting up in cold weather

Antifreeze helps the engine run cooler in the hot months and prevents the coolant from freezing in cold weather.

On installed transformer a test is performed to check weather it has any oil leakage or not, the test is called pressure test, more precisely pressure leakage test.

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.

No, but it doesn't make sense to drain it and change to water. Modern antifreeze also contains additives that are corrosion inhibitors, and it raises the boiling point.

The lower radiator hose is exposed the more weather.

You may do so, however you car will not run at it' s optimum temperature. Because antifreeze is "thicker" (viscosity wise) than water it retains heat longer. Some people run only water and this cools the car fine however......water doesn't contain the lubricating and anti corossion properties that antifreeze does (let's not forget that antifreeze when mixed 50/50 with water keeps you engune from freezing in cold weather)..... If you run ONLY water (i.e. Have no issues with freezing) add a pruduct such as "waterwetter" or "black ice" for lubricity purposes.

Ford vehicles come from the factory with a 50 / 50 mix of distilled water and the correct type of antifreeze for the vehicle for year round use Ford states not to exceed 60% antifreeze in the mix ( colder climates etcetera )

Vehicle manufacturers recommend a 50/50 mixture of antifreeze/water in the cooling system all year round. The antifreeze helps the engine run cooler in hotter weather and prevents freezing in colder weather.

Heater hose has a leak, freee plugs expanded in freezing weather because not enough antifreeze , engine block cracked or a blown head gasket.

The engine produces heat no matter the weather. The cooling system must have a problem such as a bad thermostat, bad fan clutch, plugged radiator, missing radiator shroud or low on coolant because of a leak somewhere.

They affect the weather by polluting the air .They pollute the air by the burning of the plastic bottles and other thing.

Fish survive because they have special proteins in their body which is called antifreeze so the fish won't die while they are in any type of cold weather.

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.
