Why do you put antifreeze in your car?

[ad_1]
If you’re only adding antifreeze, then open the hood and locate either the radiator cap or the coolant overflow bottle under the hood. Turn the cap counterclockwise to open it, and add your manufacturer-recommended antifreeze until the radiator is full, or the coolant overflow bottle is filled to the “COLD” line.
Antifreeze is an agent that stops the water that cools your engine from freezing in cold climates and also prevents the water from boiling if it gets too hot. This is pumped around the engine by the water pump, to both keep things cool and prevent overheating.
As well as preventing water from freezing up, antifreeze raises the boiling point of engine coolant to prevent overheating. The stuff also protects your engine from corrosion, aids heat transfer, and prevents scale from building up internally.
Antifreeze is commonly used as one of the components of a coolant mixture – coolant is generally a 50-50 split between antifreeze and water. Antifreeze (specifically the ethylene glycol, which is its main ingredient) is used to lower the freezing point of the liquid that circulates around the engine of a vehicle.

how long does coolant last in a car? When the word coolant is used in can mean a couple of things. Coolant made up of antifreeze and water out of your household tap, 50-50 solution, would last for around 3 years. Coolant made up of antifreeze and distilled (de-ionised) water, 50-50 solution, should last for around 5 years.
