Red Line WaterWetter SuperCoolant Additive - 12oz Bottle

Red Line WaterWetter is a concentrated wetting agent that improves the heat transfer of your cooling system by reducing the surface tension of the coolant. This process eliminates the vapor barrier and localized bubbles that form on hot internal metal surfaces, which can reduce cylinder head temperatures by up to 20°F. Whether you are running a high-performance street engine or a dedicated track car, this additive ensures more efficient thermal management under high-load conditions.

• Reduces or eliminates the vapor barrier to drop coolant temperatures by up to 20°F.
• Improves heat transfer in both ethylene and propylene glycol systems.
• Compatible with all types of antifreeze, including DEX-COOL and long-life versions.
• Provides superior rust and corrosion protection, satisfying ASTM D2570 and ASTM D1384 standards.
• Allows for the safe use of straight water in racing environments or reduced glycol levels in warm climates.
• Formula contains no ethylene glycol.

Directions for Use: Use one 12oz bottle for most passenger cars and light trucks. For smaller cooling systems, use 1oz (approximately 3 to 4 capfuls) per quart of coolant. Vehicles with high-capacity cooling systems may require two bottles.
