This replacement coolant overflow tank is designed to match OE fitment and restore correct coolant level monitoring and overflow control for Cummins 6.7L-equipped Ram trucks. Molded from heat- and pressure-resistant plastic and supplied with the sensor port and matching cap, the assembly is a direct-fit option for owners replacing worn, cracked, or leaking expansion tanks. Confirm your vehicle’s year and part number before ordering to ensure compatibility.

How will this tank restore my truck's cooling system?

Replacing a damaged reservoir ensures proper coolant expansion control and accurate level sensing, preventing air from entering the cooling loop and helping the cooling system function as intended. The included sensor port allows the truck’s ECU and dash gauge to monitor fluid level and trigger alerts if topping up is needed.

• Restores coolant overflow capacity and venting.
• Re-establishes level sensing via the sensor opening.
• Prevents coolant loss from cracks or degraded plastic.
