Red Line 81215 SuperCool Performance Antifreeze/Coolant, Ready to Use Formula - 1 Gallon (4 Pack)

Reduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20°. Superior heat transfer properties compared to glycol-based antifreeze. Compatible with new or used antifreeze (including DEX-COOL® and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems. Improves heat transfer and reduces cylinder head temperature. Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems. Cleans and lubricates water pump seals. Reduces cavitation and complexes with hard water to reduce scaling. Does not lower cooling system below the thermostatically-controlled temperature. 50/50 prediluted, ready-to-use formula. Maximizes cooling system performance with superior protection against cavitation corrosion/erosion. Enhances heat transfer, reducing operating temperatures by up to 20°F. FOR ALL MAKES / ALL MODELS / ANY COOLANT COLOR: Cars, SUVs, and minivans; Trucks: Light and Medium Duty. 5 year / 150,000 mile protection. Compatible with gas and diesel engines.
