Mopar Performance Radiator Inlet Hose Upper Coolant Hose

The Mopar Performance Radiator Inlet Hose, also called an upper radiator hose or upper coolant hose, carries hot coolant from the engine to the top of the radiator. Coolant releases its heat in the radiator, so a sound inlet hose helps the engine hold a stable operating temperature.

Key Features:

• Made to Mopar specifications for fit, form, and function
• Reinforced rubber construction that resists heat and oil
• Flexible enough to handle engine movement, vibration, and repeated heat cycles
• Molded to the shape of the original hose, which helps it route cleanly and seal at the connections
• A direct-replacement design for a straightforward installation

Rubber coolant hoses wear over time. Cracks, swelling, soft spots, or coolant seepage are signs a hose needs replacing. Replacing a worn upper radiator hose helps prevent coolant loss and overheating. Choose the variant that matches your application from the options on this page.
