All-source 573906 Antifreeze Coolant Concentrate 1 Gallon

Product Description

The ALL-SOURCE 573906 is a concentrated antifreeze and coolant formulated to protect gasoline and diesel engine cooling systems from corrosion, scale, and sludge buildup. The low silicate formula delivers freeze protection down to -62 degrees F and boil-over protection up to 274 degrees F when mixed to the appropriate concentration. This 1-gallon concentrate is intended for use by fleet maintenance technicians, mechanics, and service professionals working on light- and heavy-duty gasoline or diesel-powered equipment.

This coolant concentrate is suited for gasoline and diesel engine cooling systems in automotive, fleet, and equipment maintenance applications. It is designed for systems that do not require an extended-life antifreeze formulation. The low silicate chemistry provides reliable corrosion inhibition across common cooling system metals including iron, aluminum, copper, and brass found in radiators, water pumps, and engine blocks.

Key Features

• Freeze protection rated to -62 degrees F at full concentration
• Boil-over protection rated to 274 degrees F
• Low silicate formulation for compatible cooling system metals
• Guards against corrosion, scale, and sludge in gasoline and diesel engines
• 1-gallon concentrate - mix with distilled water per system requirements
• Not suitable for systems requiring extended-life antifreeze chemistry

Compatibility

Designed for use in gasoline and diesel engine cooling systems that do not require extended-life antifreeze. Not compatible with systems specifying OAT, HOAT, or other extended-life coolant formulations.

Installation Notes

Always drain and flush the cooling system before adding new coolant to avoid mixing incompatible chemistries. Mix concentrate with distilled water to achieve the desired freeze and boil-over protection range before filling. Power down the engine and allow it to cool completely before opening the radiator cap or drain. Dispose of used coolant in accordance with local environmental regulations.
