If the freezing point is estimated to be insufficient then it should be amplified by adding antifreeze to the refrigeration system. Measurement can be done with a hygrometer and a refractometer. Therefore, besides the level, the freezing point of the coolant is also measured. Frequent refilling of water into the cooling system dilutes the mixture and raises the freezing point of the coolant. Depending on the composition of the mixture of antifreeze and water, the coolant has its freezing point. 10 Best Engine Coolants and Antifreeze 1. Antifreeze is used to protect the refrigerant from freezing. In this condition, it may cause the engine block, head, radiator, and other parts of the engine and cooling system to break. In winter, when the temperature is below 0 ☌, the water freezes and expands. Engine overheating can cause serious damage.ĭistilled water with a freezing point of 0 ☌ is used for the coolant. Do not use engine coolant, antifreeze or windshield washer fluid outside of its specified function and vehicle. Does not include parts or repair charges.

What Does Coolant Do for My Engine The primary purpose of coolant is transferring heat and preventing engine damage caused by freezing or boiling. Most antifreeze formulas also include ingredients to fight corrosion inside your cooling. Formulated with ethylene glycol or propylene glycol, antifreeze reduces the freezing point and raises the boiling point, so the coolant remains liquid under wider temperature extremes. Our range of antifreeze is part of our wide selection of engine oils and fluids, plus essentials like screenwash too. Antifreeze-based coolant is crucial for street vehicles.
