Compatible with new or used antifreeze (including DEX-COOL® and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems

• Compatible with new or used antifreeze (including DEX-COOL® and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
• Reduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20 degrees
• Vehicles with larger cooling systems should use two bottles, small cooling systems should use 1oz (3 to 4 capfuls) per quart
• Rust and corrosion protection allows for use of straight water in racing or reduced antifreeze levels in warm climates
• Satisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes
• Superior heat transfer properties compared to glycol-based antifreeze
• Improves heat transfer and reduces cylinder head temperature
• Use one bottle for most passenger cars and light trucks
• Contains no ethylene glycol
