Koyorad’s JR1062J radiator steps in when the original cooling gear on a Rodeo RA or Colorado RC starts to struggle. The core size of 475 by 590 millimetres keeps plenty of coolant in front of the fan on slow climbs and in stop start traffic. The 28 millimetre thickness keeps airflow moving across the fins when the bullbar and driving lights are already taking up grille space. Under the bonnet you get hose connections at 38 millimetres diameter so the radiator lines up with standard upper and lower hoses without extra adapters. The integrated transmission cooler section keeps the plumbing tidy for compatible setups. The dimensions match factory mounts on 2.4 litre and 3.0 litre models so the shroud and brackets go back where they should. That makes this radiator a smart buy if you want gear that just fits and lets you get out there again.

• Direct replacement radiator for Isuzu Rodeo RA 2.4L and 3.0L manual (2003–2008)
• Also suits Holden Colorado RC 2.4L and 3.0L models (2008–2011)
• Core height of 475 mm for strong cooling capacity
• Core width of 590 mm to maximise airflow through fins
• Core thickness of 28 mm balances coolant volume and airflow
• 38 mm inlet diameter to match standard upper hose
• 38 mm outlet diameter to match standard lower hose
• Integrated transmission cooler section for compatible driveline layouts
• OE-style dimensions to work with factory shrouds and mounts
• Suitable for 4x4 touring and towing use within listed applications

Q: How can I confirm this radiator fits my Rodeo or Colorado?

Match the engine size, year range and core dimensions. This radiator suits 2.4L and 3.0L Rodeo RA from 2003–2008 and Colorado RC from 2008–2011. Measure your old core height and width and check for about 475 mm high and 590 mm wide. Also check that your hose diameters are close to 38 mm. If those numbers line up, you are looking at the right gear.

Q: Does this radiator include an integrated transmission cooler?

Yes, this radiator includes a built-in transmission cooler section. That means the auto transmission lines connect straight to the radiator without a separate cooler if the vehicle was set up that way from factory. Many owners still add an external cooler for heavy towing. You can keep the in-radiator cooler in series if your installer recommends it.

Q: Do I need to reuse my original fan shroud and caps?

Yes, you reuse the factory shroud, cap and hoses. This radiator is built to OE-style dimensions so the shroud bolts back to the new core. Reusing the correct shroud helps direct airflow across the full 475 mm by 590 mm core area. Make sure the radiator cap matches the vehicle’s specified pressure rating. Replace old hoses if they are soft or cracked when you install the new unit.

Q: Can this radiator handle towing and high ambient temperatures?

The large 475 mm high and 590 mm wide core provides plenty of surface area for heat transfer. That helps when towing in high ambient temperatures common across Australia. Keeping the cooling system clean and full of the right coolant mix is still critical. A blocked grille, mud in the fins or old coolant can undo the benefit of a new radiator. Regular checks before big trips will help the whole setup go the distance.

Suits Isuzu Rodeo RA 2.4L and 3.0L manual models built from 2003 to 2008. Suits Holden Colorado RC 2.4L and 3.0L models built from 2008 to 2011. Fitment applies to vehicles requiring a radiator with a 475 mm high by 590 mm wide core and 38 mm inlet and outlet. Check core dimensions and hose diameters against the original radiator before installation. Professional installation is recommended for correct bleeding and cooling system operation.
