Detailed Description

Four Seasons Fan Clutch 46070 is a thermal engine cooling fan clutch engineered for standard-rotation applications. It features a 7.01-inch clutch diameter, 3.07-inch mount diameter, 1.25-inch pilot diameter, and a 0.45-inch pilot depth, with M6 x 1.0 hole threading and a 6.48-inch fan bolt circle. The aluminum body and heavy-duty design support dependable operation in vehicles that rely on a mechanical fan clutch to regulate airflow through the radiator and engine bay.

This part cross-references Gates 22182 and Dorman 46070 for the same application. It is a direct-fit cooling solution for many Nissan Frontier, Xterra, Pathfinder, NV1500, NV2500, and NV3500 models, plus Suzuki Equator coverage in the listed years. Four Seasons 46070 is a practical choice when replacing a worn thermal fan clutch that no longer engages correctly or maintains stable engine temperature.

What It Is Used For

• Restoring proper fan engagement when the engine runs hotter than normal
• Addressing noisy, slipping, or inconsistent fan clutch operation
• Replacing a worn thermal clutch that reduces radiator airflow
• Supporting cooling performance during towing, hauling, or stop-and-go driving
• Correcting overheating concerns tied to mechanical fan drive wear

Installation Notes and Tips

Verify standard rotation, flange mounting, bolt pattern, and pilot dimensions before installation. This unit is not electronic and mounting hardware is not included. Confirm clearance around the fan blade and check the cooling fan assembly for wear, damage, or imbalance before reassembly. For best results, inspect the radiator, water pump, and belt drive system at the same time.

Quality Assurance

Four Seasons 46070 is a new replacement fan clutch that meets or exceeds OEM specifications and is performance rated for cooling system service. It is built for the listed Nissan Frontier, Xterra, Pathfinder, NV1500, NV2500, NV3500, and Suzuki Equator applications.
