PRESTONE Command Heavy-Duty ESI Antifreeze Coolant 50/50 1 gal Purple 10100

SKU CH-S5VX-YW2TP

Pre-charged heavy-duty coolant protects on- and off-road systems in extreme temperatures with a ready-to-use 50/50 blend

  • Ready-to-use 50/50 mix simplifies top-offs and fills
  • Extended service interval formula reduces maintenance frequency on heavy-duty engines
  • Pre-charged with SCA eliminates initial supplemental coolant additive requirement
  • Compatible with conventional heavy-duty coolants and all filter technologies
  • Protects on- and off-road systems in extreme cold and heat

Heavy-Duty Extended Service Interval Coolant

Prestone Command Heavy-Duty ESI Antifreeze Coolant is a ready-to-use 50/50 formulation designed for heavy-duty cooling systems on both on-road and off-road vehicles. It protects in extreme cold and heat conditions. The ethylene glycol blend with inhibitors is compatible with conventional heavy-duty antifreeze coolants and all filter technologies.

Pre-Charged SCA Formula Eliminates Initial

This coolant comes pre-charged with supplemental coolant additives, removing the need for an initial SCA precharge on new vehicles or recharged systems. The formula is intended to simplify maintenance by eliminating that first additive step. It is convenient for topping off existing systems without additional mixing.

One-Gallon Volume Suited for Top-Offs

The one-gallon container provides enough volume for routine top-offs or smaller system refills. It offers headroom for standard maintenance intervals on compatible heavy-duty equipment. Larger cooling system flushes or complete fills on high-capacity engines will require multiple containers.

Questions about this item

Does the pre-charged SCA formula mean I can skip the initial supplemental coolant additive charge on a fresh heavy-duty system?

Yes, the extended service interval blend is designed to eliminate the initial SCA pre-charge on new or recharged heavy-duty cooling systems.

Will the ethylene glycol inhibitor package remain compatible if I top off with a different conventional heavy-duty coolant later?

The formula is compatible with conventional heavy-duty antifreeze coolants and all filter technologies, so topping off with another approved product will not break the inhibitor balance.

How does the ready-to-use 50/50 mix affect heat dissipation and freeze protection during continuous high-load operation?

The 50/50 ratio delivers standard freeze and boil-over protection for heavy-duty engines running under sustained load in extreme cold or heat.
