This Koyorad radiator drops into Toyota Prado autos from 1996 to 2003 in the RZJ and VZJ 3.4 L V6 range, with a core size of 575x638x27 mm that lines up with factory shrouds and fans. You get 34 mm inlet and outlet necks, so the existing hoses stay put when you swap the gear over in the shed. Inside the tanks there is a built-in transmission cooler running about 375 mm across the base, keeping the auto fluid in check when you tow or crawl in low range. The wide 638 mm face and 575 mm height give plenty of fin area for slow hill climbs and hot-bitumen highway runs, making this radiator a smart buy for keeping an older Prado setup ready to get out there.

Q: Does this radiator fit manual Toyota Prado models from 1996 to 2003?

This radiator is specified for automatic Toyota Prado models from 1996 to 2003 only. The integrated 375 mm transmission cooler is intended for auto transmissions. Manual variants often use a different radiator specification without the same cooler arrangement. Always cross-check your VIN and existing radiator configuration before ordering.

Q: What engine type is this Koyorad radiator suited to?

It suits Prado models with the 3.4L V6 petrol engine in the RZJ and VZJ range. These engines were factory-fitted in many Australian-delivered Prados between 1996 and 2003. Matching the 3.4L V6 and build years helps ensure the core size and hose locations line up. If your engine code differs, confirm measurements against your current radiator.

Q: Does this radiator include an internal transmission cooler?

Yes, it includes an internal transmission cooler measuring 375 mm in length. This cooler is built into the lower tank area and connects to the automatic transmission lines. The setup uses the same basic layout as the factory Prado auto radiator. Always flush or cap the cooler ports correctly during installation.

Q: What hose diameters does this radiator use?

The inlet and outlet necks both use a 34 mm diameter. This matches the listed hose connection size for the compatible Prado models. Checking your existing top and bottom radiator hoses for the same internal diameter avoids clamp mismatch. If your current hoses are worn, replacing them with 34 mm units at the same time is good practice.

Suits Toyota Prado automatic models built between 1996 and 2003 in RZJ and VZJ 3.4L V6 Surf variants. Radiator includes an integrated transmission cooler with a length of 375 mm for auto transmission applications. Fitment requires matching the core size of 575 mm height by 638 mm width by 27 mm thickness and checking 34 mm inlet and outlet hose diameters against the existing setup.
