Koyorad’s JR2047J radiator steps in with a core height of 550 mm and width of 525 mm to keep Hilux engines steady on long hauls. The 38 mm core thickness gives the coolant enough dwell time to dump heat without choking airflow. Inlet and outlet necks at 34 mm line up with the stock hoses on KZN 3.0L and VZN 3.4L Hilux models from the early 2000s. You can run this gear on Hilux KZN 3.0L from 1999 to 2005 and VZN 3.4L from 2002 to 2005 without chasing odd brackets. The integrated transmission cooler is ready for driveline setups that need it on touring or towing duty. Factory-style tanks and mounting points keep shrouds and fans in the right spot. The dimensions match what Toyota used so repairs stay simple in the shed or on the road.

Q: Does this radiator suit automatic transmission Hilux models?

This specific listing suits manual transmission Hilux variants. The radiator includes an integrated cooler section but the fitment details reference manual and turbo diesel setups, so auto models may use a different part number. Check your VIN and transmission type against workshop data. Matching the core size and hose layout before ordering will avoid downtime.

Q: Can I reuse my original radiator cap and hoses with this unit?

Yes, the inlet and outlet necks are 34 mm so standard-size Hilux hoses and caps of the same spec will fit. Inspect old hoses for cracks or softness before refitting. Many mechanics prefer new clamps with a new radiator. Fresh coolant to the correct spec will also help protect the new core from internal corrosion.

Q: Do I need to modify the fan shroud or mounts?

No, the listed dimensions match the factory-style core height and width used on these Hilux models. The shroud should bolt back to its normal points if it is original or an OEM-style replacement. Always trial fit the shroud before fully tightening the radiator mounts. Check fan-to-core clearance when the engine is rocked on its mounts.

Q: What coolant capacity change should I expect with this radiator?

The overall capacity will be similar to the factory unit because the core size and thickness are comparable. You should still drain and measure the old coolant as a guide when buying new fluid. Always follow the engine manufacturer’s recommended coolant type and mix ratio. Bleed air from the system after install to prevent hot spots around the head and block.
