Coolant does much more than simply cool your engine. It also protects your engine and other components from liner pitting, scale, corrosion and freeze damage in cold weather. This is accomplished by combining the following components in proportions appropriate for the application:
The function of glycol is to provide freeze protection, and water improves boil-over protection and helps dissolve inhibitors. Inhibitors provide protection against erosion, corrosion and cavitation or pitting of your cooling system components. Without the right inhibitors in the correct proportion, an engine can quickly fall prey to damage:
Any one of these issues can eventually put a truck out of service when it's least expected. That means it's critical to make sure your coolant’s chemistry includes the best inhibitors possible to prevent damage.
Conventional coolant chemistry requires added inhibitors, also known as supplemental coolant additives (SCAs), for heavy-duty use. Without adding inhibitors, you could see liner damage within 50,000 miles. A fully formulated or heavy-duty conventional coolant is pre-balanced with SCAs, but periodically requires additional SCAs to maintain the appropriate ratio. These coolants must be changed every 200,000-300,000 miles or 2-3 years, with periodic testing and addition of SCAs between changes.
Extended life coolant chemistry includes superior inhibitors, known as Organic Additive Technology (OAT), and doesn't require additional SCAs. Some coolants, such as TRP® Extended Life Coolant, boost liner cavitation protection even further by adding nitrite to OAT, creating Nitrite Organic Additive Technology (NOAT). The NOAT-based TRP® Extended Life Coolant can offer up to one million miles or eight years of protection with the use of just one extender.
In addition to extended life coolant, TRP® offers both conventional and heavy-duty conventional coolant formulations to cover every application. As an added safety measure, all TRP® coolants include a bittering agent to prevent ingestion by animals or children.
By combining a high quality product, such as TRP® Extended Life Coolant, with regular cooling maintenance, you can maintain proper cooling system balance and protect your engine. Visit your nearest authorized TRP® retailer to check your cooling system and learn more about TRP® Coolant.
