This Jayrad JFC011 fan clutch bolts onto 4JJ1-TC and 4JK1-E5 diesel engines with a flange mount and 32mm pilot hole, so it lines up with standard Colorado, Rodeo, D-Max and MU-X cooling setups. With a 91.5mm overall height and 177mm fan bolt circle, the hub keeps the fan in the right spot in the shroud to move air when you are hauling or crawling in low range.

The alloy body runs a 192mm outside diameter packed with cooling fins to pull heat out of the viscous fluid, which helps the clutch grip when engine bay temps climb on long hills or slow sand work. The flange screw design spreads load across the pump nose, limiting stress on bearings. If your old clutch freewheels or locks solid, this spec-matched unit is a smart buy to get cooling performance back in line.

Q: How can I confirm this fan clutch suits my ute?

Match the engine code and key dimensions. Check your vehicle uses a 4JJ1-TC or 4JK1-E5 engine and visually confirm a flange-mount fan clutch. Measure the pilot on your existing hub to confirm it is 32mm. You can also check the fan bolt circle is close to 177mm. If these match, this JFC011 unit is the correct style.

Q: When should a fan clutch typically be replaced?

Replace it when the fan freewheels cold and hot or stays fully locked. Overheating at low speed, roaring fan noise at highway speed, or play in the hub are common signs. A failed clutch can stress the water pump and reduce cooling performance. Swapping it before a big trip helps avoid heat issues under load.

Q: Does this fan clutch affect highway fuel use?

Yes, if the old unit was locked on it can reduce drag. A healthy viscous clutch lets the fan slip more at highway speeds, which can lighten the load on the engine. That usually means less fan noise in cruise. It can also help belts and bearings last longer because they see lower constant torque.

Q: Can I reuse my existing fan and shroud with this clutch?

Yes, the hub is made to work with the standard fan and shroud from the listed vehicles. The 177mm fan bolt circle suits the OE fan blade. The 91.5mm overall height keeps the fan close to its original position in the shroud. This keeps airflow patterns similar to factory. Always inspect the fan blades for cracks before refitting.

This Jayrad JFC011 fan clutch suits Holden Colorado and Holden Rodeo models fitted with the 4JJ1-TC or 4JK1-E5 engines. It also suits Isuzu D-Max and Isuzu MU-X models with the same 4JJ1-TC or 4JK1-E5 diesel engines. Check the existing clutch for matching flange screw type and a 32mm pilot hole before installation. Professional installation is recommended to maintain correct engine cooling performance.
