Modified 95 Degrees AISIN Fan Clutch, 80-Series Heavy Duty – 1FZ-FE Blue Hub Fan Clutch Mod
Help your 1FZ-FE engine stay cool and run at the optimal temperature! Our modified OEM Aisin Fan Clutch engages at 95 degrees as we change the CST Fluid formula and adjust the temperature springs to achieve a long-term solution with a higher “lock-up” rate. This modification is known as the “Blue Hub Fan Clutch Mod” for 80-Series Toyota Land Cruisers. This modification is prevalent because it correctly matches the fan engagement to the water pump rotation dynamics. This is our “Standard Modified” version, and we also have the Super-HD Mod version.

We have been running this same modified AISIN fan clutch for three years on our 80-Series in hot temperatures, with A/C on, driving on oversized wheels (37″) at low RPM at high altitudes (9 -10,000ft average) with no issues here in Colorado Springs (6,000+ ft elevation just in town). Why does elevation matter?
We also now have a Super-HD Mod version. Do you have a turbocharged or supercharged 1FZ-FE engine? Work in the oil fields, idling all day, on the phone, windows rolled up, and A/C on? All while sitting in the middle of higher-heat areas such as Death Valley and Laredo, Texas.
See our article “Elevation Doesn’t Care! Keeping Land Cruisers Cool.” We know elevation wreaks havoc on our Land Cruiser’s cooling systems, especially here in the dry air of Colorado Springs, sitting at 6,200 feet, and especially heading up the passes that lead into the glorious Colorado Rockies.

Since you are changing the Fan Clutch, when was the last time you changed your Fan Belt and Alternator Belt? Do you have spares stuffed in your 80-Series rear storage compartment as emergency spares? Now is a good time to add belts when changing the Fan Clutch!

It’s “hit or miss” these days, as we either have them in stock or they are backordered for 3-4 weeks, as both the fan clutch and CST fluid are currently out of stock nationwide.
