. Solubility _____,
It has a much lower freezing point than water. if the coolant freezes it expands cauing pressure damage or even leaks. It also contains anti corrosion chemicals to prevent rust inside the engine.
In the engine and radiatorIn the engine and radiator
Yes.If you have no antifreeze in the radiator or engine,sometimes it will freeze.Usually a freeze plug in the engine will pop out before any major damage is done. Sometimes the block will crack,or the radiator will crack or burst if no anti freeze is in the system.
If the antifreeze/coolant level in the radiator gets low enough, the engine will over heat. If the engine overheats enough, it could warp the intake manifold requiring a very expensive repair. Do yourelf a favor and get theleak repaired.
Because there is antifreeze int he system and it takes a while to burn through. Also replace the bottom hose too. <> If it smokes from under the hood, It has antifreeze on the engine exterior, You can wash it off. Or just drive it and it will burn off. If it smokes from the exhaust, There is engine damage.
You risk damage to the engine as the coolant not only protects it against freezing conditions but also prevents corrrosion to the components,especially parts made from alloy;eg the cylinder head and water pump
antifreeze does not enter the engine at any time. locate and follow your radiator hoses and follow then and check for cracks or punctures.
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.
look for antifreeze coming out of the radiator as the engine warms up after a cold start.
You should never use transmission fluid in a radiator.You can use water without antifreeze in a radiator, but if the engine gets below 32 F (0 C) the water will freeze and severely damage the engine.
To the overflow tank and if the radiator has a cap,you will need to fill it with the engine cold.
No. It can result in damage to the engine if you loose all of your coolant. I have damaged an Alternator by coolant spraying on it. There is some risk if you try to work on the radiator or remove the cap when the engine is HOT. The fluid can spray on you can cause burns. Antifreeze is not harmful to you if you spill it on you. ( cats and dogs are attracted to antifreeze and could possibly kill them if they drink it )
