Pressure test the cooling system Monitor antifreeze level
Find source and fix it.
You may have blown a head gasket, check you oil to see if the antifreeze is leaking into there.
Find where it is running out and repair the cause.
Find the source and repair it.
Find the overall balance of antifreeze: amount of antifreeze to start with + the amount of pure antifreeze to add = amount of antifreeze in the final solution Let X be the amount of pure antifreeze to add in gallons. (70 * 0.25) + X = 0.80 * (70+X) 17.5 + X = 56 + 0.8X 0.2X = 56 - 17.5 0.2X = 38.5 X = 38.5/0.2 = 192.5 gallons
You can find antifreeze at most large department stores in the automotive section or at an automotive store.
It seems so. You can find more detail in the Wikipedia article on "Antifreeze protein".
If your antifreeze got hat enough to boil, you need to find out why then replace it. It will not do the job it is supposed to.
OK, find the leak and repair it.
there is an antifreeze overflow tank, look on the radiator next to the radiator cap and there should be a smallish hose, follow it and you will find the tank.
To create a 45% antifreeze solution from 1 gallon (128 ounces) of pure antifreeze, you need to determine how much of the solution should consist of antifreeze. Since you want 45% antifreeze, you can set up the equation: 0.45 * (128 + x) = 128, where x is the amount of water added. Solving for x, you find that you need to add approximately 104 ounces of water to achieve a 45% antifreeze solution.
