This Guide Fan is designed for Isuzu NPR, Isuzu NPR-HD, Isuzu NQR, and Isuzu NRR trucks manufactured between 1995 and 2016, equipped with 4BD2 3.9L, 4HE1 4.8L, or 4HK1 5.2L diesel engines.

The guide fan (fan shroud support or fan bracket) positions and secures the radiator fan to ensure optimal airflow across the radiator. Proper alignment is essential for engine cooling efficiency, preventing overheating and maintaining consistent engine performance.

A damaged or worn guide fan may result in:

• Radiator fan misalignment

• Excessive fan vibration

• Reduced cooling efficiency

• Overheating under load or hot weather

• Premature wear of fan blades or mounting points

Replacing a worn guide fan restores proper airflow alignment, reduces vibration, and maintains engine cooling system integrity. Manufactured to OEM specifications for durability, exact mounting, and long-term reliability.
