Hot Shot's Secret red antifreeze 1 gallon — ready-to-use 50/50 coolant, SCA protection

Hot Shot's Secret 1G750KR Red Antifreeze is a ready-to-use 1-gallon 50/50 coolant blend formulated for conventional and extended-life systems, pre-charged with supplemental additives and a bittering agent for safer handling.

This one-gallon jug of Hot Shot's Secret red antifreeze comes pre-mixed 50/50 with distilled water so it’s ready to pour into most passenger vehicles, light trucks, and heavy-duty applications that accept red-colored coolant. It’s designed for compatibility across conventional and many extended-life formulations, and includes an initial dose of Supplemental Coolant Additive (SCA) to support corrosion protection in mixed-metal cooling systems. The product is also dyed red for system identification and contains a bittering agent to discourage accidental ingestion.

How do I use this red antifreeze in my vehicle?

Pour directly from the one-gallon container into the vehicle’s coolant reservoir or radiator when the engine is cold, following the vehicle manufacturer’s fill and bleed procedures. Because it’s pre-mixed 50/50 with distilled water, no additional dilution is necessary for typical climates and seasonal use.

• Ready-to-use 50/50 mix — no additional water required
• Fill only when engine is cool to avoid injury or boiling-over
• Follow your owner’s manual for proper coolant capacity and bleed steps

Will this coolant work with other brands or extended-life coolants?

Yes — the formula is compatible with many conventional and extended-life coolants, making it suitable for topping off or refilling mixed-coolant systems. It contains an initial Supplemental Coolant Additive to help protect engine components when systems include different formulations.

• Compatible with conventional and many extended-life brands
• Pre-charged with SCA for added protection in mixed systems
• Check vehicle manufacturer recommendations before long-term mixing
