Coolant's Main Job Is To Transfer Heat

Much like lubricants, however, coolants aren't as simple as they appear.

TECH TALK
Dan Peterson, Vice President, AMSOIL Technical Development

Dan Peterson
Vice President,
Technical Development

Motor oil has been a big focus for AMSOIL over the years and this will continue. We spend a lot of time talking about the differences in motor oil designs and quality because it has a major impact on vehicle performance and longevity. We have not focused very often on the other side of the engine block, but it is an important component of overall vehicle maintenance. In the mid-80s, many preventable engine failures were caused directly by problems with the cooling system - up to 50 percent according to some heavy-duty sources. Today, this number has been reduced significantly with the use of fully formulated coolants, but cooling systems continue to be a big source of maintenance problems.

There are some basic jobs that a coolant has to perform, just like motor oil, or engine life is significantly reduced. The main job of the coolant is to keep the engine cool. Many systems also use coolant to reduce the temperature of transmission fluid. In heavy-duty applications coolants are used in liquid-cooled brakes and to cool gases in exhaust gas recirculation (EGR) systems. Regardless of the component, the main job of coolants is to transfer heat.

Seems pretty simple, so why don't we just use water alone? It's cheap, readily available and does a good job transferring heat. Seems like a good idea, but straight water contributes to excessive corrosion in engines and contributes to cavitation issues, erosive wear and failures. Additionally, water has a nasty tendency to freeze below 32 degrees Fahrenheit, which makes it hard to use during winter in northern climates.

Unless you use purified water, there are a bunch of dissolved solids in most water that produce scale on hot surfaces, resulting in cooling system failures. Water also wants to boil at 212 degrees Fahrenheit so without modification, you will have a tendency to create steam and boil over the cooling system. Modern coolant designs address all the issues outlined above and more. A coolant is typically a mix of either ethylene glycol (EG), propylene glycol (PG) or glycerin, additives and water. You can think of the EG or PG as the functional base fluid. The main job of this component is to keep the coolant from freezing and boiling over in use. The additives are used to control pH and foaming, protect metal surfaces and neutralize acids produced as coolants age. Water is used as a medium for heat transfer as it does an excellent job in this area.

Like lubricants, there are a number of different designs and quality levels of coolants on the market. There also are a number of different terms used to describe coolant additive technologies, such as conventional, fully formulated, OAT, HOAT, NAPS and so on. These general terms attempt to classify different ways to provide the chemistries used to perform the additive jobs described above. The important thing to remember is to use the coolant type required by the vehicle and be careful when mixing fluids.

There are a couple key things to keep in mind in caring for your coolant and coolant system. The first is the source of water you use to mix the coolant. Poor-quality water contributes to corrosion, scale and build-up of dissolved solids in the cooling system. All of these create major issues regardless of the type or quality of coolant used in the system. You can quickly ruin an expensive coolant with poor-quality water.

Another key maintenance item is to simply check your coolant level regularly. If your coolant falls below the critical level, heat will build up quickly and expand critical engine parts, including the block housing the pistons. As this area expands, metal parts come in closer contact, resulting in excessive wear and creating permanent damage to your engine. Check the level and fix leaks promptly.

The final thing you can do is change your coolant when you see signs of issues. Small changes in color are not indicators of coolant condition, but if it appears to contain particles the system needs to be cleaned and the coolant should be changed. If there is a significant abnormal odor when checking your coolant, the system should be inspected and coolant changed. If you suspect an issue when checking the level, Oil Analyzers has a coolant analysis service that can help diagnose issues and help find the source of the problem.

Light- and heavy-duty vehicle designs are changing faster than ever. Powersports applications are also evolving and moving toward liquid cooling for many applications. Most of the design changes are placing increasingly more stress on both motor oils and coolants. AMSOIL is closely watching and testing to ensure our products and recommendations are compatible with this quickly changing environment. Published, AMSOIL Magazine 10/14.

AMSOIL Synthetic Diesel Oil Articles and Testimonials


"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.

AMSOIL Now An ISO Certified Manufacturer
AMSOIL recently received ISO 9001:2000 certification of our Quality Management System (QMS). NSF International Strategic Registrations is the registrar that has verified our QMS meets the requirements of the ISO 9001:2000 standard, the most widely utilized quality standard throughout the world for quality management systems. ISO standards are used by over 300,000 companies worldwide setting rigorous standards for businesses, government and industry.

ISO 9001:2000 is applicable to any manufacturing and service organization providing a framework for system development that focuses on the customer, quality system performance and ongoing improvement. AMSOIL received ISO 9001:2000 registration under the scope: synthetic lubricants blending, packaging, and other fulfillment directly associated with lubricant product.

The ISO certification puts AMSOIL in line with some of the most efficient companies in the world. It is further assurance that the products and services AMSOIL provides will continue to maintain the high level of quality the company always demanded.
