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.

It is an organic inhibitor base with nitrite and, potentially, molybdate for extra cavitation pitting control. NOAT coolant is known as an Extended Life Coolant or HD ELC. NOAT coolants have been very common in factory fill applications, but many OEMs are now transitioning to HD Nitrite Free OAT coolant. NOAT coolants protect the cooling system much longer and with less maintenance than Conventional (IAT) coolants. There is no need to monitor SCA or install SCA charged coolant filters. TMC recommended practice color is Red, but other colors are used as well. NOAT type coolant protects HD cooling system components up to 6000 hours or 300,000 miles. You can extend this protection by adding an Extender at 6000 hours or 300,000 mile interval. This gives a protection up to 12,000 hours or 600,000 miles. A lab analysis is recommended before adding the Extender. This analysis allows the technician to decide, to add an Extender, or flush and fill the system with new coolant. Do not use a charged coolant filter with NOAT HD ELC coolant. Nitrite Free Organic Acid Technology Coolant (NF OAT): This coolant is known as HD Nitrite Free Extended Life Coolant or HD NF ELC and it uses organic inhibitors and, potentially, molybdate and/or nitrate. This coolant uses organic inhibitors, molybdate and/or nitrate to help control corrosion and cavitation erosion in a cooling system. It does not contain inorganic inhibitors, such as, Silicate, Nitrite, and Borate. There is no need to monitor SCA and do not install a SCA charged coolant filter. HD NF OAT coolant is used in some HD vehicles for factory fill. The color is typically yellow, red, or blue but other colors may be used as well. HD NF OAT coolant protects the cooling system for up to 12,000 hours or 600,000 miles. No Extender is needed, but it is recommended to test the coolant at least twice a year with organic inhibitor test strips to test organic inhibitors, pH, and freeze point levels. It is also recommended to have a lab analysis completed at 6,000 hours or 300,000 miles to check the condition and contaminate levels of the coolant. Heavy Duty Coolant Technologies Overview (continued) It is not recommend to use an IAT or NOAT type coolant to top-off HD NF OAT coolant. If coolant is mixed it should not exceed 25% capacity. Follow recommended test procedures to determine if the cooling system needs to be flushed and refilled. It is also not recommended to use a HD NF OAT type coolant to top-off a HD IAT type coolant. It is acceptable with some manufacturers to top-off a HD NOAT type coolant with a HD NF OAT coolant. Always consult the OE Manufacturers recommended cooling system maintenance practices.

Remove any SCA release filters first and completely flush the cooling system with water two to three times to remove the IAT type coolant. If the cooling system shows signs of contamination utilize Prestone Command ® Heavy Duty Cooling System 2in1 Flush & Degreaser during the process and flush the cooling system with water to remove the chemical flush cleaner and contaminates. It is preferred (if equipped) to unscrew and remove all of the engine cooling system drain plugs (including block drains) to completely drain all flush water from the cooling system. An engine could hold, up to, 15% - 25% of contaminated coolant or flush water. The next few pages describe recommended testing procedures to determine if the cooling system needs maintenance or if a conversion is recommended from an IAT type coolant to Prestone Command ® HD NF Extended Life Antifreeze/Coolant.

HD NITRITE FREE EXTENDED LIFE COOLANT (NF OAT) Testing Fluid Conversion/Maintenance Plan Made with FlippingBook RkJQdWJsaXNoZXIy MTEyNjY3NA== 10Prestone TSB for Training130009252017 Technical Service Bulletin Page 10 PCTSB-2017-01 PRESTONE PRODUCTS CORPORATION 1900 West Field Court, Lake Forest, IL 60045 ©2017 Prestone Products Corporation Importance of Water Quality Testing Water Source When you use water to mix with antifreeze/coolant concentrate it is critical that the water be of the appropriate quality. Why should you check water quality? The quality of water can have a negative effect on the life and performance of the antifreeze/coolant by introducing excessive levels of corrosive ions, hard water salts, or pH destabilizing materials. Water quality is critical in order to prevent scale build-up and ensure that important chemicals in antifreeze/coolant mix- tures perform as expected and do not drop out of solution. Hardness Levels Water hardness level is determined by calcium and magnesium carbonate ion content. When water with high hardness is used in cooling systems, scale can form on cooling system surfaces and prevent efficient heat transfer. The net result can be excessive heat buildup leading to overheating, oil degradation, etc. pH Levels pH should remain in the appropriate range at all times. A pH that is too low or too high can destabilize the coolant inhibitor package causing the inhibitors to fall out of solution and in some cases form unstable gels. Any lost inhibitors can shorten the life of the coolant and reduce the corrosion protection provided by the coolant. If the pH of your water is too high or too low it should not be used to mix with antifreeze concentrates. Chloride Levels High chloride levels in water (sodium chloride) can increase the corrosion rate of aluminum and iron metal surfaces resulting in the depletion of important corrosion inhibitors out of the coolant. The net result is a reduction of corrosion protection of the engine cooling system. TEST INSTRUCTIONS Collect a water sample in a clean cup (about 8 oz.). Water sample must be between 50°F (10°C) and 130°F (54°C). Remove a strip from the bottle, DO NOT touch the pads at the end of the strip. Dip the strip in water sample for 5 seconds with a gentle, back and forth motion. Remove and shake strip briskly to remove excess liquid. Wait 25 seconds, then match Hardness and Chloride to the color chart. Match pH colors at 1 minute. When utilizing Test Strips do not use the above color chart. Use the color chart on the Test Strip Bottle or individual card.
