This Koyorad radiator slots straight into GU Y61 Patrols with TD42T 4.2 L turbo diesel and manual gearboxes from 1997 to 2007, so you can tackle long hills without watching the temp needle creep. The core sits at 450 mm high and 908 mm wide, giving plenty of face area for the factory fan and shroud when you are crawling in low range or towing.

The 35 mm thick core runs 35 mm inlet and outlet necks, so standard hoses and clamps line up without drama. The built-in transmission cooler suits the Patrol layout and keeps the plumbing tidy under the front. The OEM cross-reference to 21410-VB210 and Nis038PacM2 makes it a smart buy for workshops and home mechanics who want parts to match up cleanly on service paperwork.

Q: Does this radiator fit automatic transmission Patrol GU Y61 models?

This specific radiator is listed for manual transmission GU Y61 Patrols with the TD42T 4.2L turbo diesel engine. The hose locations and cooler arrangements on automatic models can differ, so matching the OEM part number 21410-VB210 and Nis038PacM2 reference is important. If your automatic uses a different factory number, a separate radiator variant is likely required. Check your build plate or existing radiator label before ordering.

Q: Is this radiator suitable for towing heavy caravans or camper trailers?

The core dimensions of 450 mm height, 908 mm width and 35 mm thickness provide the cooling area needed for the TD42T 4.2L engine under sustained load. For heavy towing, keeping the cooling system clean and using the correct coolant mix matters as much as the core size. Make sure the fan clutch, shroud and hoses are in good condition. A blocked grille or packed-up bull bar can still restrict airflow.

Q: Can I re-use my existing radiator cap and hoses with this unit?

The inlet and outlet necks are 35 mm in diameter, which lines up with standard hose sizing on the GU Y61 TD42T. That means most factory-style hoses and clamps will physically fit. However, old hoses can crack when disturbed, so many mechanics treat a radiator change as a good time to renew rubber. A fresh cap with the correct pressure rating also helps keep boiling margins where they should be.

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

The radiator is specified as a replacement for the factory 21410-VB210 unit in 1997–2007 GU Y61 manual models, so shroud and mount positions are intended to match OEM layout. On older vehicles, brackets can be bent and aftermarket bull bars or winches may crowd the nose area. Lining up mounts before tightening everything down helps keep the shroud centred on the fan. Any previous custom work at the front should be checked for clearance.

Suitable for Nissan Patrol GU Y61 with manual transmission from 1997 to 2007 using the TD42T 4.2L turbo diesel engine and OEM radiator part number 21410-VB210 or equivalent. Fitment suits vehicles that accept radiator reference Nis038PacM2. Professional installation is recommended to ensure correct hose alignment, fan shroud positioning and integration with the factory transmission cooler circuit. Existing coolant, hoses, clamps and caps should be inspected and replaced if worn during installation.
