Product Details
Hayden Fan Clutch 2661 is engineered as a thermal clutch for import cooling systems that rely on mechanical fan engagement rather than electronic control. The aluminum body, standard rotation, and 2.86-inch distance from clutch to mounting flange help match the original cooling fan setup on the listed Toyota Land Cruiser and Lexus LX450 applications. This part cross-references Four Seasons 36935 and Gates 22074 for the same application.
Common Cooling Issues It May Address
- Engine temperature rise at idle or low vehicle speed
- Reduced fan engagement from a worn thermal clutch
- Cooling fan noise caused by clutch wear or internal drag
- Inconsistent airflow through the radiator and condenser
- Cooling system performance loss on Toyota Land Cruiser and Lexus LX450 models
Installation Notes and Tips
Verify the fan bolt circle, mount diameter, bolt thread, and overall height before installation. This Hayden 2661 uses an M6 x 1.0 hole pattern and a 4-bolt flange mount, and mounting hardware is not included. Confirm standard rotation and thermal clutch style against the original part to ensure proper fitment on 1993-1997 Toyota Land Cruiser and 1996-1997 Lexus LX450 applications.
Quality Assurance
Hayden Fan Clutch products are built for replacement use in cooling system service and this part is listed as new and performance rated. The 2661 is specified to meet or exceed OEM requirements for the covered Toyota and Lexus applications.
