This Koyorad radiator steps straight into a Nissan Navara D22 running the YD25 2.5 litre diesel and manual gearbox, so you can get out there without chasing odd fittings. The core measures 450 millimetres high and 686 millimetres wide, giving solid cooling area for beach runs or slow work on fire trails. Matching 35 millimetre inlet and outlet diameters line up with factory hoses, making it a smart buy when the old core is tired. The radiator uses a 25 millimetre thick core to balance coolant volume with airflow through the grille on D22 models from 2009 onwards. The layout keeps things simple, with hose positions and mounting points set up for standard front ends. That means the gear handles typical Aussie heat loads from towing or sand driving without fancy add ons. Straight facts, solid fit, and cooling capacity sized for the YD25 diesel.

Q: Will this radiator fit an automatic transmission Navara D22?

This radiator is listed for manual transmission Navara D22 models. Auto models often use a different radiator with an internal transmission cooler. Always compare your existing unit for transmission cooler line fittings. If your current radiator has metal line ports, this manual version will not be suitable.

Q: How can I confirm this radiator matches my Navara D22?

Match the engine code, year and dimensions. This unit suits YD25 2.5L diesel Navara D22 utes from 2009-on with a core size of 450 x 686 x 25 mm. Check that your hoses are 35 mm and that mounting points and thickness look similar. When in doubt, measure your old radiator before ordering.

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

You can reuse hoses if they are in good condition and match the 35 mm inlet and outlet. Many owners replace old hoses at the same time to avoid future leaks. Cracked, soft or swollen hoses should be replaced. Fresh coolant and a new cap are also commonly fitted during radiator changes.

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

The core size and 25 mm thickness are suited to the heat load of the YD25 2.5L diesel in standard form. Keeping the fins clean and the cooling system maintained is important for towing work. A properly fitted radiator with correct coolant mix will help control temperatures. Always monitor gauges on long climbs or hot days.
