PEAK Final Charge Global Antifreeze/Coolant Concentrate 1 Gal — Extended‑Life, Heavy‑Duty Protection for EGR/SCR Engines

PEAK Final Charge Global is a concentrated, extended‑life antifreeze/coolant designed to protect heavy‑duty diesel, gasoline and natural gas engine cooling systems for up to one million miles when mixed and maintained correctly.

This one‑gallon concentrate blends long‑lasting corrosion inhibitors with a formula engineered for modern, high‑temperature powertrains. It supports engines that use exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) by helping manage heat transfer and protecting cooling system metals. The product is compatible with a wide range of systems when diluted, and it includes a gentle additive package formulated to be non‑abrasive to water pump seals.

How do I mix and use this concentrate safely?

Mix according to your engine manufacturer's recommended coolant concentration—commonly a 50/50 blend with water for freeze and boil protection, but always verify for heavy‑duty applications. Avoid mixing large amounts of incompatible formulations; keep contamination under 25% to preserve corrosion protection. Use clean, de‑ionized or distilled water when possible to minimize mineral deposits.

• Common mix: 1 part concentrate to 1 part water for general service.
• For extreme climates, adjust mix per OEM guidance.
• Do not exceed 25% contaminated coolant when blending with other types.
• Use distilled water to reduce scaling and extend service life.

Will this coolant work with modern EGR and SCR equipped engines?

Yes — the formulation is designed to handle higher operating temperatures found in engines with EGR and SCR systems. Its heat‑transfer characteristics help maintain stable coolant temperatures under heavy loads. However, always confirm compatibility with the engine manufacturer's approved coolant specifications before use.

• Optimized for high‑temperature heat transfer needs.
• Suitable for diesel, gasoline and natural gas heavy‑duty engines.
• Helps protect components downstream of hotter exhaust treatment systems.
• Check OEM spec sheet for approved inhibitor chemistries.

How long does protection last and what maintenance keeps it effective?

When properly mixed and maintained, this extended‑life concentrate can protect cooling systems up to one million on‑road miles. Longevity depends on correct dilution, avoiding cross‑contamination, and routine system inspections. Periodic coolant testing and scheduled flushes will preserve inhibitor levels and prevent deposits that shorten service life.

• Potential protection up to one million miles with proper care.
• Regularly test coolant concentration and pH.
• Flush system if contamination exceeds recommended limits.
• Inspect hoses, clamps and water pump seals during service intervals.

Does the formula affect seals, and are there any safety notes?

The product uses a non‑abrasive inhibitor package intended to be gentle on water pump seals, improving seal life compared with harsher formulas. It contains a bittering agent (Denatonium Benzoate) to discourage accidental ingestion. Always handle coolant with care, store out of reach of children and pets, and follow local disposal regulations for spent coolant.

• Non‑abrasive chemistry helps extend seal lifespan.
• Includes bittering agent for safety against ingestion.
• Use gloves and eye protection during handling.
• Dispose of used coolant at authorized recycling or hazardous waste facilities.

Who is this for: PEAK Final Charge Global concentrate is aimed at fleet managers, heavy‑duty vehicle technicians, and owner‑operators who need a versatile, long‑life coolant solution for diesel, gasoline, and natural gas engines. Choose this product if you require robust corrosion protection, compatibility with modern high‑temperature powertrains, and the ability to achieve extended service intervals when following proper dilution and maintenance practices.
