This Koyorad radiator runs a core height of 740 mm and suits Nissan Patrol GQ diesel wagons from 1988 to 1997 with a manual box so you can tackle steep low-range climbs without watching the temp gauge creep. The 437 mm core width and 36 mm thickness give plenty of surface area for slow work in sand or mud when airflow through the grille is average at best. The tanks and core pair with 40 mm inlet and outlet necks that line up with standard hoses so the kit drops into a factory-style cooling setup without drama. A built-in transmission cooler section is on hand for compatible driveline layouts where extra heat control matters on long highway stints. The dimensions stick close to OE spec so fan and shroud clearance stay workable on older touring rigs. It is a smart buy if you want straightforward Patrol cooling performance.

Q: Does this radiator fit automatic Nissan Patrol GQ models?

This radiator is specified for manual transmission GQ diesel models. Automatic models often use a different radiator configuration and cooler routing. Always compare core size and mounting points with your existing unit. If your vehicle is automatic, confirm part numbers with a mechanic before ordering. Using an incorrect radiator can lead to hose alignment issues and poor cooling performance.

Q: Do I need new hoses when installing this radiator?

Not always, but it is recommended to inspect the hoses. Old hoses can go soft, crack, or swell near the clamps, especially on vehicles from the late 80s and 90s. If there is any sign of wear, replace them while the system is open. Fresh hoses help the 40 mm inlet and outlet seal properly and reduce the risk of leaks.

Q: Is the transmission cooler inside this radiator suitable for heavy towing?

The built-in cooler is sized for typical use within the vehicle’s original towing ratings. For regular heavy towing or extended high-heat work, many owners add an auxiliary cooler in series. This takes some load off the in-radiator cooler. A mechanic or auto trans specialist can advise on the right setup for your Patrol or Maverick.

Q: How should I prepare the cooling system before fitting the new radiator?

Drain the old coolant completely and flush the system with clean water. Check the thermostat, radiator cap, and fan clutch while everything is accessible. Refill with a quality coolant mix to the ratio recommended by your engine manufacturer. Correct preparation helps the new 740 mm core work at its best and reduces the chance of future overheating.

Suitable for Nissan Patrol GQ diesel models built between 1988 and 1997 with manual transmission only. Also suits equivalent Ford Maverick vehicles with the same platform and manual gearbox. Confirm core height of 740 mm and width of 437 mm against the existing radiator before purchase. Professional installation is recommended to ensure correct hose alignment and fan shroud fitment. Existing coolant, hoses and radiator cap may need replacement if worn or degraded.
