Today’s heavy-duty engines are running for more miles and more years than ever before, going the distance to move heaven and earth. They maximize productivity and fuel economy by running at higher temperatures for more service hours.

These big-time efforts test an engine’s limits, so the coolant you choose can be make or break. That’s why FINAL CHARGE PRO-SERIES is setting the new standard for cooling system protection. An incredible industry-leading 1.5 million miles on the road or 36,000 hours on the jobsite. How is this even possible? In a word, chemistry.

Regular coolants can fail to protect the engine’s wet sleeve liners, allowing bubbles to bore into the metal, resulting in big-ticket repairs. Our proprietary technology blocks imploding bubbles for outstanding liner-pitting protection.

Other coolants can allow scale to form, blocking critical heat transfer. So FINAL CHARGE PRO-SERIES uses a proprietary technology containing scale inhibitors to prevent deposit formation, and keep operating temperatures where they belong.

Our formula is free from borate, nitrite, silicate and amine to provide optimal protection for critical aluminum components, like water pumps and radiators. And 2-EHA free to ensure complete compatibility with gaskets and hoses.

All this and more is why this is an unsurpassed life of the engine coolant. You expect more from your engine, so expect more from your coolant too. FINAL CHARGE PRO-SERIES — Performance at its PEAK.
