This Jayrad fan clutch bolts to the hub on Toyota Hilux, HiAce and Prado 3.0 L diesel engines that use the 1KZ-TE or 1KDFTV layout, so you can tackle slow tracks without watching the temp gauge. A flange screw mount and 22 mm pilot hole line up with the factory pulley, and the 76 mm overall height keeps the fan sitting where Toyota intended.

The finned metal body spans 168 mm across and uses a 136 mm fan bolt circle, so your standard fan blade sits tight and moves plenty of air across the radiator. The viscous clutch setup locks up harder as things heat up, which helps on steep low-range climbs and soft sand where airflow drops. For anyone running these Toyotas as tourers or work utes, this is a smart buy when the old clutch freewheels or leaks.

Q: How can I confirm this Jayrad fan clutch fits my Toyota?

Match your engine code and key dimensions. Check that your vehicle runs a 1KZ-TE or 1KDFTV 3.0L diesel and was built after 2007. Then confirm your existing clutch uses a flange mount with a 22 mm pilot. Measuring the fan bolt circle at around 136 mm also helps. If these line up, this clutch will suit most KZN, KZH, KDH and KZJ applications.

Q: When should a fan clutch typically be replaced on these engines?

Replace it when engagement or freewheel changes. If the fan roars constantly from cold, the clutch may be locked and wasting power. If it freewheels when the engine is hot or the temp gauge climbs in traffic, the clutch may be weak. Any visible leaks around the hub are another cue. Many owners see issues from higher kilometre use or heavy towing.

Q: Do I need special tools to install this fan clutch?

Basic hand tools usually handle the job. Most setups only require spanners or sockets that match the fan and hub fasteners. Access can be tight around shrouds and belts, so patience helps. Supporting the fan and clutch as a single assembly reduces strain on the bolts. Many owners still prefer a workshop if they are not confident around cooling gear.

Q: Should I replace the fan clutch when upgrading other cooling parts?

It is often worth doing together. If you are fitting a new radiator or water pump on a high kilometre 3.0L diesel, an old clutch can be a weak link. Replacing it at the same time avoids having to strip the front of the engine again later. A fresh clutch helps the new radiator and coolant work as intended under towing and touring loads.
