Red Line Diesel Water Wetter - 15oz. (Case of 12)

Red Line Diesel Water Wetter – 15oz. Case of 12

Red Line 80213 Diesel Water Wetter is a unique cooling system additive specifically formulated for diesel engines including Cummins, Duramax, and Power Stroke applications. The RED80213 case of 12 contains twelve 15-ounce bottles of Red Line's scientifically proven coolant additive that reduces the operating temperature of any diesel cooling system by increasing the heat transfer capability of water and coolant-water mixtures. Red Line 80213 works by reducing the surface tension of the coolant at the wetted wall of the engine, improving the efficiency of heat transfer at the metal/coolant interface a significant advantage in high-heat diesel applications. Each 15oz bottle of RED80213 treats a full cooling system and is compatible with all antifreeze/coolant formulations. Red Line 80213 also provides corrosion inhibition, rust prevention, and lubrication for water pump seals. Purchasing the RED80213 case of 12 provides outstanding per-bottle cost savings for shops, fleets, or enthusiasts who rely on diesel vehicles year-round.

Why Use Red Line 80213 in Your Diesel

Diesel engines generate significantly more heat per cycle than gasoline engines, making cooling system efficiency critical to engine longevity. Red Line 80213 addresses this by improving the fundamental thermodynamics of the coolant-to-metal heat transfer — something that conventional coolant additives do not specifically target. This is particularly valuable for turbocharged diesel trucks used for towing, high-mileage fleet operation, or performance applications where thermal management is a priority.

Frequently Asked Questions

1. Is Red Line 80213 the same as the regular Water Wetter? No. Red Line 80213 is a diesel-specific formula. The regular Water Wetter (80204) is for gasoline engines. Always use the correct formula for your application.
2. How much temperature reduction can I expect? Real-world results vary by application, but Red Line Water Wetter products are documented to reduce coolant temperatures by 10-30 degrees Fahrenheit in various tests.
3. Is RED80213 compatible with extended-life coolants (OAT, HOAT)? Yes. Red Line 80213 is compatible with all antifreeze formulations including OAT, HOAT, and conventional green antifreeze.
4. Can I use RED80213 in a racing or performance diesel? Absolutely. Red Line originally developed Water Wetter for motorsport applications where thermal management is critical.
5. How often should I add RED80213? Add one 15oz bottle per cooling system fill. Reapply each time the coolant is changed.
6. Will RED80213 damage my seals or hoses? Red Line 80213 is formulated to be compatible with rubber hoses, seals, and gaskets. No damage occurs with proper use.
7. Is RED80213 appropriate for use in a Duramax? Yes. Red Line specifically calls out Cummins, Duramax, and Power Stroke diesel engines as primary applications for RED80213.
8. Does the case-of-12 pricing offer savings over single bottles? Yes. The RED80213 case of 12 provides a lower per-bottle cost compared to individual bottles, making it ideal for shops and high-volume users.

Usage Instructions

Add one 15oz bottle of Red Line 80213 per cooling system at the time of coolant fill. Pour directly into the radiator or overflow reservoir. Run the engine to operating temperature and check coolant level. Top off with additional coolant if needed. Reapply with each coolant change or annually.
