This Jayrad fan clutch keeps the mechanical fan on your HDJ100 Land Cruiser doing its job when the gauge starts creeping up. The unit runs a flange mount with a 16 mm pilot hole, so it centres cleanly on the hub and lines up with the 136 mm fan bolt circle. You get a direct swap for the original clutch, with an 81.5 mm overall height that keeps the fan in the sweet spot of the shroud. Jayrad builds this clutch with a finned alloy body at 168 mm outside diameter, so it can dump heat fast in slow traffic or low‑range climbs. The flange screw type mount stays solid when you are loading the 4.2 litre 1HDFTE across long highway pulls or sand work. The dimensions mirror the standard setup, so the gear works with factory belts and pulleys without mucking around with spacing or brackets.

Q: Does this Jayrad fan clutch fit all HDJ100 Land Cruisers?

It suits post-2007 HDJ100 models with the 4.2L 1HDFTE turbo diesel engine. Earlier engines or petrol variants can run different hub and fan dimensions. Always match the 16 mm pilot and 136 mm fan bolt circle to your existing clutch. A quick check with a vernier or tape before ordering avoids downtime.

Q: Do I need a new fan blade with this clutch?

You can reuse a factory fan that matches the 136 mm bolt pattern and correct offset. Inspect the plastic fan for cracks around the bolt holes before refitting it. Replace the fan if any blades are warped or chipped. Balanced fan and clutch combinations reduce vibration and bearing wear.

Q: Should I replace other cooling parts at the same time?

Many owners pair a new fan clutch with fresh coolant and a radiator inspection. A healthy clutch still relies on clear radiator fins and correct coolant mix to control temperature. Checking hoses and belts during the job helps prevent roadside stops. Planning this as one job saves labour time.

Q: How can I confirm this clutch matches my old one?

Measure the overall height, pilot diameter and fan bolt circle on your current clutch and compare to 81.5 mm, 16 mm and 136 mm. The outside diameter should be close to 168 mm around the fins. Matching these key sizes confirms alignment with shrouds and pulleys. If measurements differ, speak with our crew before buying.
