This Koyorad radiator slots into a Nissan X-Trail T31 with a core height of 450 mm and width of 686 mm, so it keeps QR25DE and MR20DE engines under control on long hills and soft tracks. The extra long outlet lines up with the factory hose run, and the 35 mm inlet and outlet let you reuse the standard hoses without drama. You can run it on both auto and manual gearboxes from 2007-on.

The 16 mm core thickness gives solid cooling without choking airflow when you are crawling in low range. An integrated transmission cooler looks after automatic models that see regular towing or beach runs. The alloy core and plastic tanks keep weight down while still coping with hot Aussie days. If your old radiator is tired, this is a smart buy to keep the X-Trail ready for weekend trips.
