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?

What to do when water freezes in automobile?

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.

Why does the heater not work in cold weather when it works fine in warm weather on a 1992 Plymouth Acclaim that has a new thermostat and the core and radiator and water pump are okay?

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

Can you add antifreeze to a car without flushing radiator?

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.

What kind of antifreeze does a 1996 Chrysler Sebring use?

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.

Which facts about the use of antifreeze illustrates a rule that governs the physical world?

Antifreeze keeps water from freezing when it is cold out. The antifreeze liquid lowers the freezing point of the water. Even when freezing (to a slurry) it does not form solid ice that can rupture the radiator. The antifreeze combines the water to form a liquid with a lower freezing point than water alone.

What is the purpose of antifreeze in cars?

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

Which antifreeze-coolant would one use for a 2000 Jeep GC Laredo?

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

What happens when a car runs out of antifreeze?

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

Why do you add antifreeze to your car?

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.

Are plastic patio benches more weather resistant than wooden ones?

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

Why is antifreeze required to be added to an engines coolant?

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

What does antifreeze do for your car?

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

What is pressure test for transformmer and how to test?

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.

How do you replace coolant water in a Daewoo matiz?

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.

What did you use before antifreeze in cars?

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.

Can you put straight antifreeze in a radiator?

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.

Which cooling system hose is normally subjected to the roughest service life?

The lower radiator hose is exposed the more weather.

Where is plastic produced?

Does an auto need antifreeze in warm weather?

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.

Do you need engine coolant all the time in a Chevy 95 1500 and where COLD OR HOT?

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.

Why does a car overheat in cold weather?

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.

What could be wrong when antifreeze is coming out of the side in the middle of the engine?

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

What else can you check on a 1998 Jeep Cherokee overheating It only overheats after idling and cools down when Im driving I replaced the radiator thermostat water pump all hoses belts thermo sensor?

not an expert but try seeing if your radiator fan is cycling on. if not check fan relay. check fan itself by hooking diectly to battery to see if its good Bad radiator cap, blockage, new stat is bad, bad coolant temp sensor, air pocket in system, worn blades on waterpump, inadequete mixture of coolant and water. Below is someone else's post-not mine- that I thought was worth reading: check the radiator itself. Corrosion will build up on the aluminum vents inside, and prevent flow of coolant, and even though your water pump is pumping, the flow is restricted (depending on the antifreeze mix you use), and the solution to that is to have it flushed out. They sell bottles of stuff that you add to your radiator to clean it, or you have it professionally done. To have your radiator flushed insures it is clean, and insures you have the PROPER mix of antifreeze. Too often, shops use the 50/50 mix of antifreeze, and common knowledge dictates that bigger 8 cylinder engines need a richer mixture, like 70/30, especially during the summer. Hot water has way much more pressure than hot antifreeze, and the friction of the mostly water mix could be relative to the "running hot" condition. so, 1st.....Run a richer mix of antifreeze, drive it and see the temperature change. 2nd.....Flush and clean the radiator. Betcha nothing your mixture of antifreeze is too thin to handle this hot weather. Hope it helps. Peace. It only overheats with the air conditioner on and IDLING after normal driving and reaching operating temperature. It cools to normal temperature after resuming driving speed. Last year I replaced the water pump, new radiator, water sensor, radiator cap, fan clutch, flushed the engine, replaced all hoses and belts, cleaned the air conditioner coil, antifreeze, I just don't know what else it can be?

How do fish survive in cold weather?

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.
