I have a 91 Ford Escort that has two caps. one is on the radiator itself and one next to it that says coolant only. how do I know where the antifreeze goes? does a mixture of coolant and water go in the radiator or does only water go in radiator and coolant in the other one? I have never seen an engine with this. could you help explain it?
how to change antifreeze in vauxhall vectra B
How do you change the antifreeze in a 2004 Eddie Baurer ford Expedition.
To change the antifreeze on a Mercedes, locate the drain plug on the bottom of the radiator. Drain the fluid into a pan and refill it.
The antifreeze provides corrosion protection and gradually becomes acidic as the corrosion protection declines
The corrosion protection package in the antifreeze does " wear out " so if you do not change the antifreeze / preferably distilled water mix the coolant mix will become acidic and not provide the corrosion protection that is required
Standard antifreeze should be changed every two years. Long life antifreeze needs changing every five years.
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
To change the antifreeze on a 2003 Alero once the car cools remove that radiator pressure cap. Pour in a gallon of pre mixed coolant.
To change the antifreeze on a 2003 Saturn Ion-3, locate the drain plug on the bottom of the radiator. Drain the liquid into a pan before refilling it.
If the engine is overheating or when you service the cooling system and change the antifreeze.
Actually, antifreeze will freeze. It just freezes at a much lower temperature than ordinary water. But it can freeze, and the chemical structure of antifreeze is such that the molecules will not change state (liquid to solid -- freeze) except at the very lowest temperatures. A lot of thermal energy must be removed from antifreeze to cause the molecules to "hook up" and the stuff to change state into a solid. It's based on the nature of the chemical structure of antifreeze.
Hard water can cause antifreeze color to change due to mineral deposits and impurities from the water being mixed with the antifreeze. This can result in the antifreeze appearing darker or discolored. It is recommended to use distilled water when mixing antifreeze to avoid color changes and ensure optimal performance.
