This mixture ratio provides protection against corrosion and freezing even at F C. During winters in extremely cold areas, the mixture is increased to a ratio of , which provides freezing protection at F C. Designed for both diesel and gasoline engines, the coolant has low-silicate, pH, anti-phosphate technology that protects all metals, like aluminum against corrosion.
To protect the components of the modern engine against freezing in winter and boil over in summer, it is diluted in ratio. Additionally, for optimum protection, the mixture is made in ratios. It also has a high-quality defoamer system and contains less than parts per million of silicon as required by the vehicle. Find what coolant to use for BMW.

So, next time during coolant filing situation, make use of this guide and choose the best option for your vehicle. In truth, the requirements on coolant for stateof-the-art engines are extremely high. Modern engines are becoming lighter in weight, more compact and more efficient. The end result is an engine that is running hotter. Car coolants are a mixture of water and antifreeze. Water has a thermal conductivity that is approximately 4 times higher than glycol.
More water in the mixture results in better cooling. In addition to lowering the freezing temperature, glycol also increases the boiling point, which protects the engine against overheating. Lubrication Antifreeze has lubricating properties, enabling the coolant to lubricate components in the cooling system e. Protection from corrosion The inhibitors in the antifreeze also protects against corrosion and cavitation, as well as preventing deposits and foaming.
Silicate is an additive with excellent corrosion prevention properties. If the mixing ratio of antifreeze to water is calculated wrongly, the level of protective inhibitors in the coolant may be too low. It can lead to corrosion throughout the entire cooling system.
In this case, rust, lime scale or dirt may destroy the surfaces of the mechanical shaft seal. As a result, the sealing of the water pump bearing is no longer guaranteed.
Tip: It is advisable to clean and flush the cooling system when replacing the coolant. Do not re-use the coolant that is drained off. Also remember that coolant is a hazardous waste. Silicate Silicate is now an indispensable additive, given the increasing requirements in respect of material compatibility, corrosion protection, extended service intervals and the use of lighter weight materials in vehicle construction. However, the proportion in newer antifreeze has been reduced compared to older antifreezes with blue and yellow colouring.
Nevertheless, some manufacturers e. BMW and Mercedes-Benz are still using antifreeze with a higher proportion of silicate. Of the antifreezes available from febi Bilstein, there are three that no longer differ in colour compared to their predecessors. The three antifreezes containing purple dye, making them visually identical, have monoethylene glycol MEG as their base, but have differences in the amounts of additives see table below.
Glycerol has similar properties to glycol, but is more environmentally compatible and less energy is consumed by comparison during its manufacturing. Corrosion protection and material compatibility have been further enhanced by new additives. Mixability Generally speaking, pay attention to the colour of antifreeze and always use the same colour in the vehicle. In spite of this, almost all febi antifreezes can be mixed. The only exception is febi red antifreeze febi that must never be mixed with blue febi or yellow febi antifreeze.
Service Intervals Over time, some of the inhibitors are used up and no longer function as intended. As a result, the coolant looses frost and corrosion protection, as well as lubricating effects and thermal conductivity.
Foaming and deposits may also occur. Wear is particularly intensive if a leak occurs, or exhaust gasses get into the cooling system e. It is therefore advisable to check the coolant regularly and replace it if necessary.

I bought the gallon size since it's cheaper than any of the gallons at my local auto parts store and is the correct fluid. With time, they lead to corrosion and damage to the cylinder gasket, water pump, and radiator. They may also damage your engine to the extent that you will require a new one. Usually, BMW coolants have no phosphate and nitrite, unlike their counterparts. This feature is the reason as to why they resist corrosion and build-up on aluminum components. Also, it is essential to note that the BMW coolant does not come pre-mixed.
Be careful to follow the mixing instructions. Too much water is inadequate for proper boilover and freeze-protection. On the other hand, too much antifreeze concentrate may cause your engine to overheat. However, this is not recommendable. Always ensure you have a spare coolant at boot of your car for such cases. Water helps to cool down the engine but not as well as a coolant.
Water boils fast yet at a lower temperature than the genuine coolant. Its primary purpose is to absorb the excess heat generated by a running engine. Coolant deteriorates with time. Therefore, it is recommendable to check your engine coolant at least twice a year. Alternatively, you can schedule your checks after every 30, or 50, miles. If the coolant level has gone down, you should top it up.
To sum it all, coolant is a vital component that every car owner must-have. Both coolants are highly effective on all BMW models. They have no nitrite or phosphate, the major corrosion catalysts. They give your engine and cooling system optimal protection against boil overs, heat damage, and corrosion.
