What’s new What’s new More than ever, old and new engine materials need secure protection against frost and rust for a full 365 days a year. Even cooling systems need high-tech solutions – and MOTOREX has the answer. The importance of regular changing Old coolant not changed in accordance with the manufacturer’s specifications can result in chemical reactions at high temperatures with disastrous consequences. Microscopic particles can be dissolved from surfaces and form deposits at other points. The result, a coating which reduces the diameter of the cooling system or may even block a coolant channel completely, is a sure sign of impending damage to the engine! The product data sheet shows the antifreeze needed and the mix for each type of protection. The antifreeze should be mixed with clean, potable-quality tap water. Manufacturers’ certification Individual certification by car manufacturers is particularly important for radiator protection agents. Certification fol- lows years of cooperation, fleet tests and testing in the laboratory and on the test bench. MOTOREX ANTIFREEZE products have a wide range of certification by the leading vehicle manufacturers, and are always a good choice. Your MOTOREX customer service representative and importer will be happy to provide detailed information.

Coolant hose with high-quality (left) and poorer-quality (right) radiator protection. Photos: BASF Once, we used alcohol diluted with water to keep our coolant from freezing in the winter. These days are now long past, however, and today, modern coolants have a whole range of functions: •protection against corrosion •protection against cavitation •protection against frost •protection against overheating • high heat transfer • temperature resistance • hard water stability • compatibility with materials • low foaming •protection against deposits Enemy Number One – corrosion Rust (corrosion) in the cooling system is the worst enemy of any material. And dealing with all the different alloys and materials with different surfaces used in engine blocks, cylinder heads and all the various sensors and switches is quite a job for any coolant. MOTOREX has risen to this major challenge by producing a range of several antifreezes customized for specific materials and manufacturer’s specifications (see table). Speaking of cavitation ... Cavitation – the formation of tiny hollow spaces or bubbles within a fluid – is another source of problems. When they burst, they release shockwaves in the cooling system that can destroy thin metal walls in the engine block. MOTOREX ANTIFREEZE avoids the problem, as laboratory testing of its cavitation, erosion and corrosion properties shows. These properties and others can only be tested in the laboratory – all the workshop can measure is the freezing point. Complex chemical composition All MOTOREX ANTIFREEZE products are based on ethylene glycol and inhibitors such as those used to protect rubber components. Depending on the product and use, nitrite, phosphate amine and silicate additives may be unnecessary. Glycol gives antifreeze a sweet taste, but it is also slightly poisonous. As a result antifreeze should always be kept well out of the reach of children! Used coolant must also always be carefully collected and properly disposed of.
