The Jayrad JR2206J radiator steps into the bay of a Toyota Land Cruiser HJ47 with a core size of 450 by 530 millimetres and gets your 4.0 litre diesel ready to tackle long climbs without creeping past 90 degrees. The 64 millimetre thick core holds more coolant than a skinny replacement, so you can sit on 100 kilometres per hour with a tray full of gear and know the temps stay in check. The tanks and core are built tough for real Aussie tracks, with 38 millimetre inlet and outlet pipes that line up with standard Land Cruiser hoses and clamps. The heavy duty layout matches the original shroud footprint, so airflow from the engine fan hits the full 450 by 530 millimetre face instead of wasting on gaps. The integrated cooler circuit suits manual setups that might see slow low range work, keeping the whole cooling system a smart buy for older rigs.

Q: Does this radiator fit all Toyota Land Cruiser HJ47 4.0L diesel models from 1964 to 1989?

It is specified to suit HJ47 4.0L diesel models built between 1964 and 1989 with manual transmission. Still, always measure your existing core at 450 x 530 x 64 mm and check hose diameters of 38 mm before ordering. Some older rigs may have swapped radiators over the years. Matching those dimensions is the safest way to confirm fit.

Q: What hose size do I need for this Jayrad JR2206J radiator?

This radiator uses 38 mm inlet and 38 mm outlet connections. You should choose upper and lower radiator hoses that match this 38 mm internal diameter. Using the right size keeps clamps from over-tightening to chase leaks. Correct hose sizing also helps coolant flow and reduces strain on the necks.

Q: Is this radiator suitable for towing and slow off-road work in hot weather?

The 64 mm core thickness and 450 x 530 mm surface area give higher coolant volume and more fin area than lighter-duty units. That design helps the 4.0L diesel shed heat while towing or crawling in low range. Pairing it with clean coolant and a good fan clutch makes a solid touring setup. Regularly checking for mud build-up on the fins will keep performance consistent.

Q: Do I need any special tools to install this radiator?

Standard hand tools usually cover removal and refit of a radiator that matches factory dimensions like this one. You will need tools to undo hose clamps, fan shroud bolts, and mounting brackets. A proper coolant drain tub helps manage old coolant safely. A torque wrench is useful for bringing mounting bolts back to manufacturer spec.
