The Mishimoto Aluminum Degas Bottle MMRT-RAM-19BK is the ultimate reliability upgrade for the RAM 6.7L Cummins cooling system. While the factory plastic expansion tank is prone to becoming brittle, cracking, and leaking over time due to constant heat cycles, this Mishimoto unit is engineered to last the life of your truck. By moving to a professional-grade aluminum construction, you eliminate the risk of a sudden coolant loss that could lead to catastrophic engine overheating. This isn't just a replacement; it is a vital system enhancement that brings heavy-duty durability to your engine bay, ensuring your cooling system can handle the high pressures and temperatures inherent in a hardworking diesel.
- TIG-Welded Aluminum Construction: Crafted from high-quality aluminum with precision TIG welds, providing maximum strength and a leak-proof seal that far outlasts standard plastic tanks.
- Internal Baffling System: Features built-in baffles that keep coolant settled and properly positioned at the overflow port, preventing air pockets from entering the system during aggressive driving or high-load towing.
- Integrated Sight Glass: Includes a convenient sight glass that allows for instant, at-a-glance coolant level monitoring without the need to open the cap and risk hot spray.
- Seamless Direct-Fit Design: Engineered specifically for the RAM 6.7L platform, this bottle drops directly into the factory location with absolutely no modifications or cutting required.
- Rugged Wrinkle Black Finish: Finished in a durable, sleek wrinkle black powder coat that resists corrosion while giving your engine bay a clean, high-performance aesthetic.
Choosing an aluminum degas bottle is an educational investment in "air management" for your coolant. In a high-performance diesel engine, air in the cooling system is a primary enemy, as it can lead to localized hotspots in the cylinder head. The internal baffling in the Mishimoto design is specifically included to combat "sloshing," ensuring that air stays at the top of the tank and coolant stays at the bottom where it belongs. This ensures a consistent supply of fluid to your water pump and radiator even when navigating steep grades or heavy braking. Whether you are building a dedicated tow rig or a refined daily driver, the MMRT-RAM-19BK provides the structural integrity and peace of mind that plastic components simply cannot offer.
