PEAK Fleet Charge SCA Precharged Coolant/Antifreeze is a concentrated, supplemental coolant additive designed for heavy-duty diesel, gasoline and natural gas engines to provide long-lasting freeze and boil-over protection when mixed to service strength.

Engine cooling systems in commercial vehicles face aggressive conditions—high loads, extended idling and hard duty cycles. PEAK Fleet Charge SCA (Supplemental Coolant Additive) precharged concentrate is formulated to restore and maintain corrosion inhibitors and pH balance in heavy-duty systems. When diluted to the recommended ratio it replenishes depleted protection and helps prolong coolant life and engine component durability without introducing incompatible chemistries.

How do I use this concentrate in my fleet cooling system?

Mix the concentrate with water to reach the manufacturer-recommended coolant concentration, or use with prediluted 50/50 solutions where specified. Always follow your engine maker's instructions for SCA application frequency and volume to ensure proper inhibitor levels and system performance.

  • Concentrate form for flexible mixing ratios per equipment specs
  • Compatible with heavy-duty diesel, gasoline and natural gas engines
  • Use test strips or lab analysis to verify SCA levels after dosing

What protection does PEAK Fleet Charge provide for heavy-duty engines?

PEAK Fleet Charge restores essential supplemental inhibitors that guard cooling system metals and help maintain freeze/boil protection when used correctly. It targets corrosion and deposit control so cooling passages and heat-transfer surfaces remain efficient under heavy operational stress.

  • Restores SCA chemistry for corrosion protection across system metals
  • Helps maintain freeze and boil-over performance when properly diluted
  • Formulated to support extended coolant life when incorporated into maintenance schedules

Is this product compatible with my existing coolant?

PEAK Fleet Charge is designed as a supplemental additive compatible with many heavy-duty coolant formulations, but you should confirm compatibility with the coolant base in your equipment before adding. Avoid mixing incompatible chemistries—consult product labels and engine maker guidance for safe blending.

  • Works with typical heavy-duty coolant formulations when used as directed
  • Precharged SCA reduces risk of under-dosing common in fleet maintenance
  • Confirm compatibility with your coolant type and engine manufacturer specifications

How often should I apply supplemental coolant additive?

Application frequency depends on engine type, operating conditions and coolant testing results. Regularly scheduled maintenance with periodic coolant analysis will indicate when additional SCA is needed to maintain protective inhibitor levels.

  • Monitor SCA concentration via test strips or lab analysis
  • Replenish according to engine maker or coolant supplier recommendations
  • More frequent dosing may be required under severe duty cycles or heavy blow-by conditions

Who is this for: PEAK Fleet Charge SCA Precharged Coolant/Antifreeze concentrate is intended for fleet managers, maintenance technicians and owner-operators responsible for heavy-duty diesel, gasoline and natural gas engine cooling systems. It suits workshops that perform routine coolant maintenance and require a concentrated, precharged supplemental product to restore inhibitor balance, reduce corrosion risk and help preserve coolant performance across demanding service intervals.
