This Koyorad radiator runs a core height of 450 millimetres so your Patrol Y61 can hold coolant temps in check when the TB45E 4.5 litre petrol works hard up long hills. The 901 millimetre core width spreads airflow right across the grille, handy when the bullbar and lights block part of the nose. The 34 millimetre core thickness keeps enough capacity without crowding the fan and shroud in the engine bay. The tanks use 35 millimetre inlet and outlet necks that line up with standard Patrol hoses, so you can swap the gear in and get out there again without odd adaptors. The built in transmission cooler suits autos that tow or sit in low range for hours. The dimensions match 1997 on Nissan Patrol Y61 Gum and T variants, so the mounting points and shrouds stay where they should.

Q: Does this radiator fit all Nissan Patrol Y61 models?

No, it suits Patrol Y61 Gum/T with the TB45E 4.5L petrol engine from 1997-on. This means it is matched to specific engine and trim combinations. If your Patrol runs a different engine code, the hose positions or core size can differ. Always confirm your engine code and compare dimensions before ordering. When in doubt, check your VIN details against your workshop manual.

Q: Is there a built-in cooler for automatic transmission fluid?

Yes, this radiator includes provision for an integrated transmission cooler. The cooler allows automatic transmission fluid to pass through dedicated internal passages. This helps manage transmission temperature when towing or working in low range. You will need to connect the factory transmission cooler lines to the new unit. Inspect old lines and fittings for wear before refitting.

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

No, it is intended as a direct replacement with standard mounting points. The core height of 450 mm and width of 901 mm align with the factory frame. The tank shape is made to work with the Patrol Y61 shroud layout. Still, it is good practice to test fit the shroud and check fan clearance before fully tightening mounts. Replace worn rubber mounts to avoid vibration.

Q: What should I check before installing this radiator in my Patrol?

Confirm engine code, hose diameters, and core size match your existing unit. The inlet and outlet are 35 mm, so hoses need to be the same size. Measure your old core to verify the 450 x 901 x 34 mm dimensions. Flush the cooling system and heater circuit to remove debris before fitting the new gear. Always refill with the correct coolant type and concentration for your engine.
