Replacement RC16030005 Upper Radiator Fan Shroud 6.6L Duramax Diesel

The Replacement RC16030005 is an upper radiator fan shroud designed as a direct-fit OEM replacement for the Chevrolet Silverado 2500 HD and 3500 HD, as well as the GMC Sierra 2500 HD and 3500 HD equipped with the 6.6L Duramax diesel engine (2011–2014 model years). It replaces OEM part number 22760017.

The radiator fan shroud plays a critical role in your truck's cooling system. It channels and concentrates airflow from the engine-driven cooling fan directly through the radiator core, maximizing heat transfer efficiency. Without a properly functioning shroud, airflow becomes turbulent and inefficient, which can lead to elevated coolant temperatures and potential engine overheating — especially under heavy towing or hauling loads common to these work-duty trucks.

Key Features:

• Direct OEM replacement — designed to match original factory fit and function
• Upper fan shroud position — pairs with the lower shroud to fully enclose the fan assembly
• Engineered specifically for the 6.6L Duramax diesel engine cooling system
• Replaces OEM part number 22760017
• Restores proper airflow management to prevent engine overheating
• Manufactured to meet or exceed original equipment specifications

This upper fan shroud is a straightforward bolt-on replacement that restores your cooling system's designed airflow efficiency. It is the correct choice for owners of 2011–2014 Chevrolet Silverado 2500 HD / 3500 HD and GMC Sierra 2500 HD / 3500 HD trucks with the 6.6L diesel engine needing to replace a cracked, broken, or missing upper shroud.
