Red Line Diesel WaterWetter - 15oz Bottle

After decades of experience and millions of happy WaterWetter users for gasoline cars, Red Line has created a diesel version, safe and effective for treating your diesel's cooling system for ultimate protection and maximum cooling efficiency. And treating your coolant is as easy as ever, making this a “no brainer” for any diesel application, especially those that will see use in hot climates or high Summer temps. 

Red Line Diesel WaterWetter Features and Benefits:

• 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
• 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
