Red Line Diesel Water Wetter

Click for a larger picture of Red Line Diesel Water Wetter

Brand: Red Line Synthetic Oil

Red Line Water Wetter improves the ability of coolant to wet heat transfer surfaces by 50%. This provides significantly better coolant contact in the cylinder head and can reduce coolant and head temperature by as much as 20° Fahrenheit.

Diesel Water Wetter has been developed specifically for heavy-duty diesel engines running more than 33% antifreeze or a supplemental corrosion inhibitor*. It should not be used with plain water. One bottle treats up to 15 gallons. A typical commercial vehicle would require one bottle.

* Diesel cars and light trucks including Cummins, Duramax, and PowerStroke engines should use the original Red Line Water Wetter (Part No. 1699) to protect against corrosion.
