BMW 228i BMW OPERATING FLUIDS - RADIATOR TECHNICAL SERVICE

BMW 228i BMW OPERATING FLUIDS - RADIATOR TECHNICAL SERVICEAuto Worldzz# BMW #228i BMW OPERATING FLUIDS - RADIATOR TECHNICAL SERVICE Fluids and sealers that are described in this Operating Fluids manual are BMW approved. Using non approved fluids or sealers can lead to premature failure and will not be covered under Warranty. 1.0 GENERAL INFORMATION ON LONG-TERM ANTIFREEZE AND CORROSION INHIBITORS The cooling system of BMW cars must only be filled with reputable brand name ethylene glycol long-term antifreeze having corrosion inhibitors that are compatible with aluminum radiators. Coolants must fulfill four basic requirements. - Guarantee sufficient cooling. - Protect various metals (gray cast iron, steel, aluminum alloys, brass, copper and solder) against corrosion. - Prevent excessive silicate gel precipitation, which may cause clogging of the cooling system. - Guarantee operation of cooling system in winter (prevent freezing of coolant) and in summer by boosting the boiling point. The quality or grade of a long-term antifreeze and corrosion inhibitor is very important to be able to protect metal (gray cast iron, steel, aluminum alloys, brass, copper and solder) in the cooling system against corrosion. It guarantees full operation of the cooling system in winter and also increases the boiling point at high outside temperatures and under heavy loads.https://youtu.be/LzeR1rD9iDM1328963513335865361
