Frequently Asked Questions
Q: What is FINAL CHARGE® GLOBAL Coolant/Antifreeze?
A: FINAL CHARGE GLOBAL Coolant/Antifreeze is a heavy-duty extended life coolant that provides total cooling system protection for 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use) using proprietary engine protecting inhibitors that do not deplete as quickly as conventional “old” technology coolant and SCA products.
Q: Why are trucks being factory filled with extended life coolant?
A: As engine and truck builders extend overall service intervals, factory fill products must be able to reach the extended service goals. Most truck manufacturers are filling new engines with extended life coolants to offer their customers the highest coolant performance, extended coolant service intervals and reduced overall maintenance costs.
Q: I’ve heard of extended life coolants. Who is using them and why?
A: Today, all leading heavy-duty OEMs, including Caterpillar® and Freightliner®, offer extended life coolant as a factory fill coolant. Extended life coolants offer the lowest cost of ownership through longer coolant life, longer coolant change intervals, and the elimination of SCAs and chemically charged filters.
Q: Do extended life coolants have “acids” in them? Does “acid based” mean it is corrosive?
A: The organic acids in FINAL CHARGE GLOBAL Coolant/Antifreeze’s patented formula have been neutralized to form highly effective corrosion inhibitors. The difference is that they are neutralized organic acids instead of the neutralized inorganic acids found in conventional heavy-duty coolants. Using neutralized acids as corrosion inhibitors in coolants is not new. Conventional coolants contain neutralized inorganic acids as inhibitors, such as phosphate and/or borate, which are derived from the neutralization of phosphoric acid and boric acid, respectively.
Q: Does FINAL CHARGE GLOBAL Coolant/Antifreeze meet Cat EC-1 requirements?
A: Fleet test in Caterpillar® 3176 & 3406 engines demonstrate that FINAL CHARGE GLOBAL Coolant/Antifreeze meets Cat EC-1 requirements. EC-1 is Caterpillar®’s specification for an extended service coolant.
Q: Besides Cat EC-1, what other OEM Specifications does FINAL CHARGE Coolant/Antifreeze meet?
A: FINAL CHARGE GLOBAL Coolant/Antifreeze also meets Cummins® 14603, Detroit Diesel® 93K217, Mercedes® 325.3; MAN 324 Typ SNF; MTU 5048; Navistar® CEMS-B1-Type IIIa; Behr Radiator and is recommended for use in all types of heavy-duty diesel gasoline and natural gas engines, making FINAL CHARGE GLOBAL Coolant/Antifreeze ideal for use in mixed fleet applications.
Q: What ASTM and TMC specifications does FINAL CHARGE Coolant/Antifreeze meet?
A: FINAL CHARGE GLOBAL Coolant/Antifreeze meets leading ASTM coolant specifications, including ASTM D-4985 and ASTM D-3306. However, it should be noted that ASTM has not established a specification for extended life coolants. Instead, current ASTM specifications are more geared toward conventional coolants that have a limited service life, typically 3-year/36,000 mile. As with ASTM, TMC has not set coolant specifications addressing extended life coolants. TMC RP-329, a long-standing heavy-duty coolant standard, is the specification for a conventional low silicate coolant that is precharged with a Supplemental Coolant Additive (SCA) containing nitrite or nitrite and molybdate. While FINAL CHARGE GLOBAL Coolant/Antifreeze definitely meets the performance requirements of TMC RP-329, it does not meet the chemical requirements of the specification.
The reason FINAL CHARGE GLOBAL Coolant/Antifreeze does not meet the chemical requirements of TMC RP-329 is that FINAL CHARGE GLOBAL Coolant/Antifreeze’s proprietary corrosion inhibitor system does not contain nitrite. With FINAL CHARGE GLOBAL Coolant/Antifreeze, nitrites, and other conventional inhibitors like phosphate and silicate, are replaced with longer lasting organic corrosion inhibitors to provide total cooling system protection. At the end of the day, it’s about coolant performance, not specific chemistry.
Q: The Industry seems to be moving away from nitrites – What is the nitrite content in FINAL CHARGE GLOBAL Coolant/Antifreeze?
A: Nitrites have long been used in fully formulated coolants, or incorporated in Supplemental Coolant Additive (SCA) then mixed with conventional coolants, for their ability to protect wet sleeve liners against cavitation and corrosion. However, nitrites in conventional and fully formulated coolants deplete, thereby reducing the level of protection provided. Also, ongoing testing and monitoring of nitrite levels are required to ensure the proper levels are maintained. To extend coolant service life and reduce maintenance time and cost associated with testing and maintaining inhibitor levels, the heavy-duty industry is moving toward nitrite-free Organic Acid Technology (OAT) coolants. With OAT coolants, conventional inhibitors, like nitrites, are replaced with organic corrosion inhibitors that deplete very slowly over time. As a result, extended life corrosion and cavitation protection is achieved without a regular schedule of liquid additives; inhibitor testing and maintenance coolant filters. FINAL CHARGE Coolant/Antifreeze is formulated with a patented nitrite-free formula.
Q: Is FINAL CHARGE GLOBAL Coolant/Antifreeze a low silicate, phosphate-free coolant?
A: FINAL CHARGE GLOBAL Coolant/Antifreeze is silicate-free. Instead of using silicates, the advanced formula contains corrosion inhibitors called organic acids. FINAL CHARGE GLOBAL Coolant/Antifreeze is also phosphate-free, nitrite-free and borate-free. The patented OAT inhibitor system provides excellent overall corrosion protection while reducing dropout, water pump seal damage, and internal cooling system scaling and storage stability often associated with conventional coolants and inhibitors.
Q: Today’s engines generate more heat than ever before. Will this affect the performance of FINAL CHARGE GLOBAL Coolant/Antifreeze?
A: Compared to the inhibitors used in conventional coolants, FINAL CHARGE GLOBAL Coolant/Antifreeze forms a thinner, longer lasting film on engine metals that protects against cavitation and corrosion. The thinner film provides better heat transfer between the engine metals and the coolant. Furthermore, FINAL CHARGE GLOBAL Coolant/Antifreeze is formulated with special proprietary stabilizers that slow down the degradation of glycol at high temperatures. This is especially important with the advent of EGR technology. The result, your engine can run cooler with FINAL CHARGE GLOBAL Coolant/Antifreeze.
Q: Does FINAL CHARGE Coolant/Antifreeze protect seals and gaskets against wear and corrosion?
A: FINAL CHARGE Coolant/Antifreeze’s patented silicate-free, phosphate-free, nitrite-free and borate-free formula provides outstanding long-term NBR, viton and especially silicon elastomer protection.
Q: Do I need to test for SCA or nitrite levels?
A: No. FINAL CHARGE GLOBAL Coolant/Antifreeze, which features a patented inhibitor system that is phosphate-free, silicate-free, nitrite-free and borate-free, reduces inhibitor drop out and eliminates the need for SCA’s and routine testing of inhibitor levels. To maintain the protection of FINAL CHARGE Coolant/Antifreeze proprietary inhibitor system, proper cooling system maintenance is required.
Q: Should I continue to use a chemically charged coolant filter after converting to FINAL CHARGE GLOBAL Coolant/Antifreeze?
A: Most coolant filters contain SCAs and are not required when using FINAL CHARGE GLOBAL Coolant/Antifreeze. Blank filters, which do not contain SCAs, should be used instead. Follow the manufacturer’s recommendations if a blank filter is recommended for the cooling system.
Q: My truck is filled with FINAL CHARGE GLOBAL Coolant/Antifreeze and I know a conventional coolant was added at top off. Will this affect the coolant performance?
A: FINAL CHARGE GLOBAL Coolant/Antifreeze is formulated with Contamination Tolerant Additives (CTAs). The performance benefits of FINAL CHARGE GLOBAL Coolant/Antifreeze will not be adversely affected by the occasional addition of conventional coolants. However, it is recommended that effort be made to keep contamination levels below 25%. This can be accomplished by topping off with FINAL CHARGE GLOBAL 50/50 Pre-Diluted Coolant/Antifreeze and the periodic adjustment of the cooling system to maintain between a 45% to 60% coolant and a 55% to 40% water mix.
Q: My truck is using a conventional coolant, and I would like to change to FINAL CHARGE GLOBAL Coolant/Antifreeze. How do I convert my truck?
A: With the FINAL CHARGE GLOBAL Extended Life Coolant Fleet Conversion Program, you can convert a truck using conventional or fully formulated coolants to FINAL CHARGE GLOBAL Coolant/Antifreeze without having to drain, flush and refill the cooling system.

For vehicles already using another brand of heavy-duty OAT coolant, simply begin and continue fulfilling all top off requirements with FINAL CHARGE GLOBAL Coolant/Antifreeze.
Q: Do I have to use special water to mix with FINAL CHARGE GLOBAL Coolant/Antifreeze?
A: For optimum performance, deionized water should be used. In cases when deionized water is not available, FINAL CHARGE GLOBAL Coolant/Antifreeze contains proprietary scale inhibitors allowing the coolant to be mixed with all water qualities without jeopardizing coolant performance or damaging engine metals.
Q: What are the recommended maintenance procedures for a truck using FINAL CHARGE GLOBAL Coolant/Antifreeze?
A: To maintain the protection of FINAL CHARGE GLOBAL Coolant/Antifreeze’s patented technology, the proper level of the proprietary inhibitor system should be present in the cooling system. This can be accomplished by adhering to the following maintenance practices:
• Do not add Supplemental Coolant Additives (SCAs) to the cooling system or use chemically charged filters.
• At every regularly scheduled preventative maintenance interval, visually inspect the coolant for contamination with sediment oil. The coolant should appear clean (not cloudy) and red in color.
• Using a refractometer, or a coolant test strip, test the freeze point of Final Charge Coolant/Antifreeze/ at least two times per year. Maintain the freeze point between -24°C (-11°F) and -51°C (-62°F).
• Use only FINAL CHARGE GLOBAL 50/50 Pre-Diluted Coolant/Antifreeze when topping off the cooling system as needed for freeze protection
