ULTRA 1PLUS UltraCool Antifreeze Coolant 50/50 Red 1 Gallon — Ready-to-Use, Corrosion Protection

UltraCool Antifreeze Coolant 50/50 is a ready-to-use red coolant formulated to protect engines from corrosion and overheating while fitting most cars and light-duty trucks.

This one-gallon, pre-mixed coolant from ULTRA 1PLUS combines corrosion inhibitors, a low-silicate and phosphate-free formula, and a defoamer system to deliver dependable heat transfer and component compatibility across a wide range of vehicle makes and models. It’s designed to meet common industry specifications so you can top off or fully replace your vehicle’s cooling system without mixing concentrate or adding extra additives.

What vehicles and cooling systems is this coolant compatible with?

UltraCool 50/50 is engineered as a universal engine coolant suitable for most passenger cars, light trucks, and many heavy-duty diesel engines. Its formulation aligns with ASTM D3306 and ASTM D4985 guidelines, increasing the likelihood it will work with systems from many manufacturers. Always check your owner’s manual for manufacturer-recommended fluid types before use.

• Compatible with modern cooling systems and many vehicles from 2000 and older
• Appropriate for popular brands such as Toyota, GM, BMW, Honda, and more
• Safe for use where ASTM D3306 or D4985-compliant fluids are specified

How does the 50/50 ready-to-use formulation simplify maintenance?

This product comes pre-diluted to a 50/50 ratio of coolant and deionized water, so there’s no measuring or mixing required. That saves time during routine top-offs or full coolant changes and removes the risk of incorrect dilution—which can reduce freeze or boil protection. It’s ideal for DIYers and professional shops who need a straightforward refill solution.

• No mixing or measuring—pour directly from the bottle
• Consistent freeze/boil protection as intended by the manufacturer
• Red color for easy identification when inspecting coolant level and condition

What types of protection and performance can I expect?

UltraCool delivers multi-purpose protection aimed at extending the life of metal and non-metal cooling system parts. Its low-silicate, phosphate-free chemistry reduces deposit formation while corrosion inhibitors protect radiators, water pumps, hoses, and gaskets. A defoamer system keeps heat-transfer surfaces clear by minimizing foam during circulation.

• Corrosion inhibitors to protect aluminum, iron, and other metals
• Low silicates and phosphate-free to limit scale and deposits
• Defoamer system protects hoses, plastics, and gaskets

How should I use and store this coolant safely?

Use UltraCool as a direct replacement or top-off when your system calls for a 50/50 ethylene- or propylene-glycol-based coolant that meets ASTM standards. Replace coolant when recommended by your vehicle manufacturer or when testing indicates diminished protection. Store the sealed container upright in a cool, dry place away from direct sunlight and extreme temperatures.

• Pour directly—no dilution required
• Follow vehicle service intervals and coolant testing recommendations
• Keep container sealed and store in a temperature-stable area

Who is this for: ULTRA 1PLUS UltraCool Antifreeze Coolant 50/50 is intended for vehicle owners, fleet managers, and repair shops who want a convenient, pre-mixed coolant that fits many makes and models. It’s a practical choice for drivers who prioritize straightforward maintenance, reliable corrosion protection, and compatibility with modern and older engines alike. Always verify compatibility with your vehicle manual before use to ensure the best results.
