By improving contact between coolant and metal surfaces, Hy-Per Lube Super Coolant helps the system move heat away from the engine more efficiently, while also protecting components from rust, corrosion and electrolysis without changing the type or color of existing antifreeze.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this product reduce engine and coolant temperatures?\u003c\/h3\u003e\n\u003cp\u003eSuper Coolant contains specialized wetting agents that change the coolant’s surface tension so it clings to and spreads over metal heat-transfer surfaces more effectively. Better metal-to-fluid contact increases heat extraction, allowing the system to dissipate temperature faster and lowering operating temps.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eImproves coolant contact with radiator, head, and block surfaces\u003c\/li\u003e\n  \u003cli\u003eAccelerates heat transfer to the radiator and fan\u003c\/li\u003e\n  \u003cli\u003eShown to reduce temperatures by up to about 20–25°F under typical conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it protect my cooling system from rust and corrosion?\u003c\/h3\u003e\n\u003cp\u003eYes — the formula includes inhibitors and lubricants that shield common cooling-system metals and water-pump seals.

Each 16 oz bottle treats cooling systems from about 12 to 20 quarts, so dosage depends on your vehicle’s total coolant capacity.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdd to radiator or overflow when engine is cold\u003c\/li\u003e\n  \u003cli\u003eOne bottle treats 12–20 quart cooling systems\u003c\/li\u003e\n  \u003cli\u003eNo need to flush existing antifreeze unless contamination is present\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: Hy-Per Lube HPC100-3PK Super Coolant is aimed at drivers and technicians who need a convenient, concentrated additive to improve cooling performance and corrosion protection without changing their existing antifreeze. It’s a practical choice for daily drivers experiencing high operating temperatures, classic cars and hot rods where mixed-metal corrosion is a concern, fleet and heavy-duty vehicle owners seeking added protection, and anyone wanting an easy-to-add treatment that helps maintain water-pump seals and reduce overheating risk. Made in the USA and sold as a three-pack, it’s also economical for multi-vehicle households or professional shops that perform frequent maintenance.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How much cooling system does one 16 oz bottle treat?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: One 16 oz bottle treats approximately 12 to 20 quarts of cooling system capacity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this with any antifreeze color or type?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
