Fits: 2019-2023 Ram 3500/4500/5500 6.7L Cummins

This Mopar Radiator Hose (Lower) 68359639AC is the perfect component for your truck. This hose plays a crucial role in the engine's cooling system by connecting the radiator to the engine block or thermostat housing, allowing coolant to flow between the two components.

This hose is a genuine Mopar component, which means it is specifically designed and manufactured for your vehicle, ensuring a perfect fit and dependable performance. Mopar parts are engineered to meet or exceed factory standards, providing the same quality as the original hose that came with the vehicle.

Typically made from high- strength rubber or a rubber-silicone blend, the lower radiator hose is designed to withstand high temperatures, pressure, and exposure to engine fluids. These hoses are built to last and resist cracking, swelling, or leaking, which can be common issues with inferior aftermarket hoses.

The lower radiator hose connects the bottom of the radiator to the engine's thermostat housing or water pump. It plays a crucial role in circulating the coolant between the engine and the radiator, ensuring the engine maintains an optimal temperature. As coolant is heated by the engine, the hose allows it to flow to the radiator to be cooled down, and then the cooled coolant returns to the engine.

As the lower radiator hose, it is positioned at the bottom of the radiator (in contrast to the upper radiator hose, which connects to the top of the radiator). The lower hose typically handles the return of coolant from the radiator to the engine.
