CATALOG NUMBER 10 www.midwestwheel.com NLINE www.midwestwheel.com Order NLINE ™ Technical Service Bulletin PCTSB-2017-01 There are four basic heavy duty coolant formulation technologies: • Inorganic Additive technology • Hybrid Organic Acid Technology • Nitrite Organic Acid Technology • Nitrite Free Organic Acid Technology There are other coolant technologies but they pertain to Automotive Light and Medium Duty vehicles. Inorganic Additive Technology Coolant (IAT): Known as HD Conventional green; other colors are used as well. This is a low silicate formulation which may include Phosphate and/or borate, nitrate, nitrite, azoles, and other inorganic compounds. This type of coolant formulation is not used today in factory fill. When used in a HD application during a complete fill SCA must be added to bring inhibitor levels up to proper protection. The HD technician must monitor and recharge the coolant, when necessary, for proper protection. The optimum change interval for this type of coolant is 3000 hours, 1 year, or 100,000 to 150,000 miles. The change interval would be based on the OE manufacturer recommended preventative maintenance schedule. HD Extended Service Interval Coolant (IAT): This is also an inorganic additive technology coolant known as an ESI type coolant. This formulation may still be used for factory fill in some heavy duty cooling systems. When following TMC recommend practices the color should be purple, pink or blue, but other colors are used as well. This is a low silicate formulation which may include Phosphate and/or borate, nitrate, nitrite, azoles and other inorganic compounds. ESI coolants are pre-charged with the acceptable levels of inhibitors and SCAs do not need to be added at initial fill or after a proper flush and fill. Supplemental Coolant Additives must be monitored and recharged when necessary. It is recommended that ESI coolants have a lab analysis completed at least once a year to monitor ethylene glycol condition and for contaminates, such as, metals, corrosion by-products, and outside contaminates. Lab analysis can be used to determine coolant condition and change interval. Hybrid Organic Acid Technology Coolant (HOAT): This type of coolant is typically not used as heavy duty factory fill in the United States. HOAT coolants typically utilize a combination of organic acids and inorganic additives, such as, low silicate, nitrite and nitrate in the inhibitor package. HOAT coolant comes in multiple colors depending on the coolant manufacturer but are typically red and yellow. Following TMC Recommended Practice: RP-365 - Coolant Maintenance Guidelines preventative maintenance on a HOAT coolant is typically performed on an interval of 25,000 miles or as specified by the engine manufacturer, similar to an HD IAT coolant.
