A cooling system additive that improves the wetting ability of water and adds rust and corrosion protection, for use in plain water or in ethylene or propylene glycol antifreeze. One bottle is enough for most passenger cars and light trucks, and larger cooling systems need two. It does not significantly lower the freezing point, so where freezing temperatures occur it must be used with antifreeze.

✓Unique agent for cooling systems that doubles the wetting ability of water
✓Rust and corrosion protection allows for use of straight water in racing or reduced antifreeze levels in warm climates
✓Improves heat transfer and reduces cylinder head temperature
✓Reduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20°
✓Compatible with new or used antifreeze (including DEX-COOL® and long-life versions) to improve the heat transfer of ethylene and propylene glycol 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
