Diesel Water Wetter Super Coolant lowers hot metal bubbles/vaper barriers, cleans/lubes water pump seals, doesn't lower cooling system below set thermostat temp, & lacks rust protection. It lowers cylinder head temp, cavitation, & scaling.

---

These products include a unique agent that lowers temperatures by reducing or eliminating bubbles or vapor barriers that form on hot metal surfaces (reduces coolant temperatures by up to 20°F). This product has superior heat transfer properties compared to glycol-based antifreeze and is compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems. This Diesel WaterWetter also improves heat transfer, reduces cylinder head temperature, cleans and lubricates water pump seals, and reduces cavitation and complexes with hard water to reduce scaling. This Super Coolant is designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems and does not lower cooling system below the thermostatically-controlled temperature. A typical diesel commercial vehicle requires one 15 oz. bottle, which treats up to 15 gallons.

• For heavy-duty diesel engines using over 33% antifreeze or a supplemental corrosion package
• Similar properties to regular WaterWetter
• No rust/corrosion inhibitors
• Not for diesel road cars or light trucks
• No ethylene glycol.
