![]() ![]() They help to reduce water-pump failures, hard-water-scale deposits and silicate gel (the green goo you often see). Extended Life Coolants offer complete cooling system component protection and contain no silicates.The user must monitor the condition of the coolant and make regular additions of SCAs to maintain additive levels. Fully formulated coolants can provide protection for up to 200,000-250,000 miles or two-three years in heavy-duty applications under normal operating conditions. Fully formulated coolants typically contain nitrite and often molybdate to prevent corrosion damage which can result from cavitation pitting in heavy-duty diesel cylinder liners. They offer a stabilized, low-silicate formula that helps reduce deposits and the risks of hard water scale. Fully Formulated Coolants contain silicate and other inorganic additives, which along with supplemental coolant additives (SCAs) provide engine and cooling system protection.While OAT additive ELCs last much longer and offer significant maintenance cost savings over the life of the coolant.īelow is some information about different coolant types. IAT additives in conventional coolants are sacrificial and will be consumed as they provide corrosion protection. The primary difference between fully formulated coolants and extended life coolants is the length of time and/or miles driven that each will remain fully effective. Each coolant type protects engines from corrosion differently and thus, when different types of coolants are mixed, both are diluted, and their effectiveness can be significantly reduced. The first is older conventional fully formulated, or inorganic acid technology (IAT) and the second is new extended life coolant (ELC) with organic acid technology (OAT). There are two distinctly different types of coolant. Not using the proper coolant can lead to problems with the cooling system of a truck. However, a lingering misconception is that all coolants are the same and interchangeable with each other. In particular, the increased use of aluminum in modern engines has made changes to coolants necessary. We have seen that as diesel engines and component materials evolve, coolant technology must follow suit. This includes troubleshooting problems, determining the need for new products, and evaluating product applications for the heavy-duty transportation industry.
