Hy-Per Lube Super Coolant additive 16 oz (3-pack) - lowers engine temps, protects seals & corrosion

This concentrated coolant treatment adds wetting agents to your cooling system to reduce surface tension in the coolant mixture, allowing faster, deeper contact with heat-transfer metal surfaces. Designed to be compatible with all antifreeze types and colors, the formula helps your radiator, water pump seals, and metal passages move heat more efficiently while offering corrosion protection for mixed-metal systems.

How does Hy-Per Lube Super Coolant help reduce overheating?

The additive contains advanced wetting agents that change coolant surface tension so the fluid spreads more evenly across hot metal areas. Better contact with the metal improves heat transfer, which can lower measured coolant and engine temperatures and reduce thermal hotspots that contribute to overheating.

• Improves coolant-to-metal contact for faster heat dissipation
• Can reduce operating temperatures by measurable degrees under load
• Helps minimize hotspots that stress gaskets and hoses

Will this product protect my cooling system components?

Yes. The formula includes corrosion inhibitors and lubricants for water pump seals, so it both shields metals from rust and helps reduce seal wear. It’s suitable for mixed-metal systems including aluminum and is formulated to limit electrolysis and corrosion commonly found in older or high-stress cooling systems.

• Protects against rust and electrochemical corrosion
• Lubricates water pump seals to extend service life
• Safe for aluminum, steel, and other common cooling system metals

How do I use one 16 oz bottle and is it compatible with my antifreeze?

Pour one 16 oz bottle into a 12–20 quart cooling system; it mixes with existing coolant and is compatible with all types and colors of antifreeze. The product works with gasoline and diesel engines and can be added during routine top-ups or as part of a maintenance service.

• Treats 12–20 quart systems per 16 oz bottle
• Mixes with all antifreeze formulations and colors
• Fits gasoline, diesel, powersports, and many heavy-duty applications

Is Hy-Per Lube Super Coolant safe and where is it made?

The formula excludes ethylene glycol and is crafted for broad compatibility rather than replacing coolant itself. It’s produced in the USA and designed as a supplemental treatment to enhance existing coolant performance without requiring a full system flush in many cases.

• Does not contain ethylene glycol
• Made in the United States
• Intended as a performance additive, not a primary coolant replacement

Who is this for: Hy-Per Lube HPC100-3PK Super Coolant is aimed at vehicle owners and technicians who want a straightforward way to improve cooling efficiency and protect system components—classic cars, hot rods, trucks, RVs, motorcycles, ATVs, heavy-duty diesels, and daily drivers that operate in hot climates or heavy loads will benefit. It’s particularly useful for mixed-metal cooling systems, older engines prone to corrosion or seal wear, and anyone seeking a simple add-on that’s compatible with existing antifreeze formulations.
