If your Hilux GUN136 with the 1GD-FTV motor is running hot at low speed, this Jayrad JFC053 fan clutch is the bit that keeps the engine fan working when it should. It suits models from 10/2015-on and matches the standard fan bolt pattern of 135 mm, so it sits in the same spot and pulls air through the factory shroud when the coolant heats up on slow climbs or in stop-start traffic.

The clutch body measures 168 mm across with an overall height of 85.8 mm, and a 22 mm pilot keeps it centred on the water pump. That means the fan tracks true and does not foul the shroud when you tackle corrugations or creek crossings. The finned metal housing helps dump heat so engagement stays consistent on long runs in high ambient temps. For a work ute or touring rig, this is a smart buy to keep the cooling system in shape.

Q: Does this fan clutch fit all Toyota Hilux models?

No. This Jayrad JFC053 fan clutch is specified for Toyota Hilux GUN136 models with the 1GD-FTV diesel engine from 10/2015 onward. If your ute has a different engine code or earlier build date, the dimensions and bolt pattern may not match. Always check the GUN136 designation and 1GD-FTV engine on the compliance plate or manual before ordering.

Q: Do I need to replace the fan blade when fitting this clutch?

Not usually. The JFC053 is built to suit the factory fan that uses a 135 mm bolt circle and a 22 mm pilot. As long as your existing fan is in good condition and matches these specs, it can be refitted to the new clutch. Inspect the fan blades for cracks or distortion and replace the fan separately if any damage is found.

Q: Can I install this fan clutch at home?

Installation is possible for someone comfortable with mechanical work and cooling systems. The job involves removing the fan shroud, uncoupling the old clutch from the water pump and refitting the new unit with correct torque on the mounting hardware. Because the fan sits close to the radiator, careful handling is needed to avoid fin damage, so many owners choose a workshop to do the swap.

Q: How do I know if my current fan clutch has failed?

Common signs include rising coolant temperature at idle, loud constant fan roar at all speeds, or visible silicone fluid leaks around the clutch body. If the fan spins freely with little resistance when the engine is hot, the clutch may not be engaging properly. A mechanic can confirm by checking engagement behaviour and comparing it to the expected feel for this style of viscous clutch.
