This Jayrad JR6145J radiator steps straight into Nissan Patrol GQ models from 1987 to 1997 with RD28 2.8L or TD42 4.2L manual setups, using a core that measures 740 mm high and 460 mm wide to match the factory shroud. The 45 mm core thickness keeps plenty of coolant volume on hand when you tow or crawl in low range. Inlet and outlet necks both sit at 40 mm so standard hoses line up without drama. You get a radiator spec that lines up with common RA733 and NIS973 listings, which makes parts cross‑checking simple before you pull the old unit. Jayrad builds the core and tanks to suit long days in Aussie heat, so the Patrol can idle or climb without the temp gauge creeping. It is smart buy gear for anyone keeping a GQ working hard instead of parked up.

Q: Will this radiator fit all Nissan Patrol GQ models?

It fits GQ Patrols from 1987–1997 with RD28 2.8L or TD42 4.2L engines and manual transmissions. Auto models use different cooling layouts, so this manual‑spec unit will not suit them. Always double‑check your build year and engine code on the compliance plate. Matching against RA733 or NIS973 references is a good final check before ordering.

Q: Do I need new hoses to install this radiator?

Not always, as the inlet and outlet diameters are both 40 mm, which matches standard GQ Patrol hoses. However, many older hoses go soft or crack when disturbed, so most mechanics suggest replacing them while the system is open. Fresh clamps and coolant are also usually fitted at the same time. That way the whole cooling setup starts from a clean baseline.

Q: Is this radiator suitable for towing and long highway trips?

Yes, the 740 mm high, 460 mm wide and 45 mm thick core is sized in line with factory heavy‑duty Patrol cooling. That footprint gives plenty of fin area for airflow at highway speeds. It also helps when you are holding revs on long climbs with a trailer on the back. Keeping the system clean and the fan shroud fitted is just as important for towing work.

Q: Can I install this radiator at home?

Many home mechanics with basic tools and a workshop manual are comfortable replacing a Patrol radiator. The job usually involves draining coolant, removing the shroud and hoses, then lifting the old unit out. Care is needed to avoid damaging fins or cross‑threading mounting hardware. If you are unsure, a professional workshop can handle the swap and pressure test the system.

Suitable for Nissan Patrol GQ models built between 1987 and 1997 with RD28 2.8L or TD42 4.2L diesel engines and manual transmissions. Fitment replaces original equipment radiator referenced as RA733 or NIS973. Installation requires transfer of existing hoses, clamps and mounting hardware from the vehicle where serviceable. Professional installation is recommended to ensure correct coolant capacity, hose routing and fan shroud clearance are maintained.
