This Jayrad fan clutch suits Toyota Land Cruiser FZJ with the 4.5L 1FZ-FE engine and uses a flange screw mount with an overall height of 90.3 mm. The unit runs a 22 mm pilot hole and a 136 mm fan blade bolt circle, so it lines up with the factory fan and pulley stack. That keeps airflow across the radiator steady when you are crawling in low range or hauling gear in 40°C valley temps.

The clutch body sits at an outside diameter of 168 mm, giving plenty of fin area to move heat out of the silicone fluid. That spec helps the hub respond predictably as the coolant temp rises instead of freewheeling. The flange screw pattern and 90.3 mm height match standard FZJ layouts, so the shroud clearance and belt run stay correct. It is straightforward cooling gear for a touring Land Cruiser that has to get out there and back again.

Q: Does this fan clutch fit all 1FZ-FE Land Cruiser variants?

It suits FZJ models specified for this Jayrad part number. Always match the flange type, overall height, pilot size and bolt circle to your original clutch before buying. Toyota used different hub patterns across markets and years. If those measurements differ, the fan or pulley alignment may be wrong.

Q: Can I install this fan clutch at home?

Yes, if you are comfortable with basic mechanical work and have the right tools. The job normally involves removing the fan shroud, unbolting the fan from the old clutch, then swapping the hub on the water pump flange. Correct torque on the flange bolts and fan bolts is important. Take care not to damage the radiator fins while working in the tight space.

Q: How can I confirm my old fan clutch is failing?

Common signs include higher engine temperatures at idle, excessive fan roar at all times, or visible silicone fluid leakage from the old hub. With the engine off and cool, a failed clutch may spin too freely or feel locked solid with no resistance. Checking for play in the bearings and fluid stains around the hub can also help you decide if replacement is due.

Q: Do I need new fan blades when replacing the clutch?

Not always, provided your existing fan blades are free from cracks, chips or warping. Inspect the plastic or metal blades closely around the root near the bolt holes. Any damage there can lead to vibration or breakage at higher rpm. Many mechanics replace bolts or hardware if they are corroded, to keep the new clutch secure over time.

Suits Toyota Land Cruiser FZJ with 4.5L 1FZ-FE engine. Verify flange screw pattern and 136 mm fan blade bolt circle against your original unit before installation. Professional installation is recommended to ensure correct torque settings and belt alignment. No additional accessories are listed as required in the supplied data.
