Fabricated Aluminum Coolant Reservoir Built to Outlast the Factory Plastic Tank on 2019-2024 Ram 6.7L Cummins
The Fleece Performance FPE-CUMM-CLNT-TNK-1924 is a direct-fit replacement aluminum coolant tank engineered specifically for 2019-2024 Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins diesel engine. The factory plastic coolant reservoir on these trucks is a known failure point, prone to cracking at the seams and welds under the thermal cycling and coolant pressure experienced by the Cummins 6.7L in daily towing and high-load applications. The FPE-CUMM-CLNT-TNK-1924 replaces the factory plastic tank with a precision TIG-welded aluminum tank powder coated in gloss black, engineered to match the factory mounting locations, factory hose routing, and factory overflow fitting positions for a clean, no-modification swap. Fleece builds this tank to handle both stock and performance applications, making it a practical upgrade for any Ram diesel owner who wants to eliminate a future coolant leak before it becomes a roadside problem.

Frequently Asked Questions
What is the Fleece FPE-CUMM-CLNT-TNK-1924?The Fleece Performance FPE-CUMM-CLNT-TNK-1924 is a direct-fit TIG-welded aluminum replacement coolant tank for the 2019-2024 Ram 2500 and Ram 3500 with the 6.7L Cummins diesel. It replaces the factory plastic coolant reservoir with a gloss black powder-coated aluminum tank that uses the same mounting points and hose ports as the factory unit.
Why does the factory Ram Cummins coolant tank fail?The factory plastic coolant reservoir on the 2019-2024 Ram 6.7L Cummins is prone to cracking at molded seam lines and attachment points due to repeated thermal cycling between cold start and operating temperature, combined with the internal pressure fluctuations typical of a high-volume diesel cooling system. Coolant leaks from a cracked tank can cause rapid overheating if not caught immediately.
Does the FPE-CUMM-CLNT-TNK-1924 fit both Ram 2500 and Ram 3500?Yes. The FPE-CUMM-CLNT-TNK-1924 is designed for both the Ram 2500 and Ram 3500 equipped with the 6.7L Cummins diesel for model years 2019 through 2024. Both trucks share the same cooling system architecture and factory coolant tank mounting configuration in this generation.
Is the FPE-CUMM-CLNT-TNK-1924 a direct bolt-on?Yes. Fleece designs the FPE-CUMM-CLNT-TNK-1924 to use the same mounting locations and hose port positions as the factory plastic tank. The installation is a direct swap with no cutting, drilling, or bracket fabrication required. A basic hand tool set is sufficient for the job.
Is this compatible with modified Cummins builds?Yes. The FPE-CUMM-CLNT-TNK-1924 aluminum tank is suitable for stock, tow-tuned, and performance-modified 6.7L Cummins applications including high-idle set points, larger radiator upgrades, and increased coolant flow scenarios associated with larger turbocharger or intercooler systems. The aluminum construction handles pressure and thermal cycling better than the factory plastic unit in all use cases.
Does the coolant tank come with hardware?Yes. The FPE-CUMM-CLNT-TNK-1924 ships with all required hardware for installation as a direct replacement. No additional hardware purchases should be necessary for a stock Ram 2500 or 3500 installation.
What warranty does Fleece Performance provide?Fleece Performance backs the FPE-CUMM-CLNT-TNK-1924 with a limited manufacturer warranty covering defects in materials and workmanship. Contact Fleece Performance directly at fleeceperformance.com for current warranty terms and claim procedures.
What is the finish on the FPE-CUMM-CLNT-TNK-1924?The aluminum coolant tank is finished in a gloss black powder coat that provides corrosion resistance and a clean factory-like appearance under the hood. The gloss black finish complements the factory engine bay appearance of the 2019-2024 Ram Cummins without requiring any additional painting or coating.
Installation Instructions
- Allow the engine to cool completely before beginning. Do not open the coolant system on a hot engine.
- Place a drain pan under the lower radiator hose and drain coolant from the system by opening the petcock or lower hose. Retain the coolant if it is still serviceable.
- Disconnect all coolant hoses from the factory plastic coolant tank, labeling each hose for correct reinstallation position.
- Remove the factory tank mounting fasteners and lift the factory plastic tank out of the engine bay.
- Transfer any sensors or fittings from the factory tank to the FPE-CUMM-CLNT-TNK-1924 if not pre-installed. Apply thread sealant where required.
- Position the FPE-CUMM-CLNT-TNK-1924 aluminum tank onto the factory mounting locations and secure with the provided hardware, torquing to specification.
- Reconnect all coolant hoses to the corresponding ports on the aluminum tank and secure with factory or new clamps.
- Refill the cooling system with the correct Cummins-approved coolant mixture. Refer to the factory service manual for capacity and coolant specification.
- Start the engine and allow it to reach operating temperature. Check for leaks at all hose connections and the tank fittings. Top off the coolant level as needed after the thermostat opens.
