RED LINE WaterWetter Special SUPER Coolant Additive - Diesel

Important: RED LINE WaterWetter is a Coolant ADDITIVE and DOES NOT contain any Antifreeze. It's main purpose is to reduce Engine Running Temperatures and raise existing Antifreeze / Coolant boiling points.

Unique agent for cooling systems that doubles the wetting ability of water.

Reduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20°

Cooling system heat transfer agent for use with antifreeze / water solutions Improves the ability of coolant to wet heat transfer surfaces by 50%. This provides significantly better coolant contact in the cylinder head temperature by as much as 10-20F. This product will not lower the temperature of the cooling system below the thermostat temperature and will be effective when the thermostat is wide open, such heavy traffic or climbing long grade. This improvement in wetting helps reduce cavitations in liners and water pumps.

Designed for heavy-duty diesel engines which use more than 33% antifreeze or a supplemental corrosion package

Similar properties and benefits to regular WaterWetter, but lacks rust and corrosion inhibitors
