Restore proper cooling performance and the original factory appearance of your 1976-80 Square Body Chevy & GMC Truck Radiator Upper Fan Shroud, SB without AC. Designed specifically for 305 and 350 small block engines without factory air conditioning, this reproduction shroud is manufactured to match the original GM design for proper fit and dependable performance.
The upper fan shroud works together with the lower shroud to help direct airflow through the radiator, allowing the engine cooling fan to pull air more efficiently. This is especially important during idling, slow driving, and hot weather when your cooling system depends on proper airflow to maintain safe engine temperatures.
After decades of use, original radiator fan shrouds often become brittle, cracked, warped, or damaged from heat and vibration. Missing or broken shrouds can allow air to bypass the radiator, reducing cooling efficiency and potentially contributing to overheating. Replacing your worn upper shroud helps restore the factory cooling system's intended performance.
Manufactured from high-quality injection molded ABS plastic, this upper fan shroud offers the durability and original appearance needed for a proper Square Body restoration. It is designed to install using the factory mounting locations and works with the correct original-style lower fan shroud.

Installation Tip
For the best cooling performance, we recommend inspecting your lower radiator fan shroud when replacing the upper section. Both pieces work together to properly surround the cooling fan and direct airflow through the radiator. Replacing damaged or missing sections helps maintain the original cooling system design and keeps your classic Square Body running at the proper temperature.
