This Jayrad radiator steps straight into a Holden Rodeo RA bay and keeps the 3.6L Colorado engine from creeping past normal temps when you tow or climb long highway grades. The core sits at 510 millimetres high and 508 millimetres wide so airflow from the factory fan and shroud is used properly. The 26 millimetre core depth helps the coolant shift heat without being too restrictive. The tanks run 34 millimetre inlet and outlet necks so your existing hoses and clamps line up without dramas. The unit includes an internal transmission cooler so you do not need extra lines hanging off the front bar. The overall 510 by 508 by 26 millimetre package suits the Rodeo RA mounting points you already have. This is the kind of cooling gear you fit once and then get out there without watching the temp gauge every hill.

Q: Does this Jayrad radiator include an internal transmission cooler?

Yes, this radiator includes an internal transmission cooler circuit. The cooler sits inside one of the end tanks and uses dedicated ports for transmission fluid lines. This keeps the cooling hardware in one compact unit. It also avoids the need for an extra external cooler in many factory-style setups.

Q: How can I confirm this radiator will fit my Holden Rodeo RA?

Check the core size and hose diameters against your existing radiator. This unit uses a core of 510 mm high, 508 mm wide and 26 mm thick with 34 mm inlet and outlet necks. If these measurements and the manual transmission match your current setup, fitment is likely correct. Always compare mounting points visually before final install.

Q: Is this radiator suitable for towing or loaded touring use?

This radiator uses a 26 mm thick alloy core sized 510 x 508 mm that suits typical towing and touring loads for a Rodeo RA. The broad face area handles extra heat from long climbs or heavier trailers. The internal transmission cooler also supports driveline temperatures under load. Regular coolant maintenance is still important for reliable performance.

Q: Do I need new hoses when installing this radiator?

The radiator uses 34 mm inlet and outlet necks, which match common factory hose sizing on the Rodeo RA. If your existing hoses are in good condition and sized correctly, they can usually be reused. Many owners still choose to replace old hoses while the system is drained. Fresh clamps and coolant are also recommended during installation.
