Radiator Fan Shroud for Nissan 4x4 Cooling System

This OEM‑grade radiator fan shroud channels airflow through the core for stable engine temperatures in traffic, towing, and off‑road use. Precision molding keeps the fan centered, improves cooling efficiency, and protects components in the bay. Built to factory geometry for a clean, bolt‑on fit.

Why this part is needed ❄️

Without a proper shroud, the fan recirculates hot under‑hood air instead of pulling fresh air through the radiator. That means weaker cooling, higher coolant temps, reduced A/C performance, and stress on the head gasket, transmission cooler, and power steering.

How it works

The shroud forms a venturi around the blades, sealing to the radiator so the fan draws evenly across the entire core. At idle and low speed it concentrates airflow; at speed it complements natural ram air for consistent heat rejection.

What happens if it’s broken ⚠️

Cracks, missing tabs, or a warped ring lead to fan tip contact, vibration, noisy operation, and up to 30% loss in cooling. Expect temp spikes in traffic, boiling coolant, and premature hose and clutch fan wear. Replace rather than glue; check blade clearance after install.
