Parts for your 1998 Nissan Navara-Radiator

1998 Nissan Navara Radiator – Purpose, Care and Replacement

Yes, a radiator is absolutely fitted to the 1998 Nissan Navara and is essential to the vehicle’s cooling system. Technical sources including the Nissan D22 Workshop Manual (Cooling System section), the Nissan FAST parts catalogue (radiator assembly 21410-**** range), and aftermarket service manuals such as Haynes for 1997–2004 Navara/Frontier confirm the D22’s liquid-cooled design. Whether it’s a KA24E petrol or TD27/QD32 diesel, the ’98 Navara runs a front-mounted aluminium-core radiator with plastic end tanks, with many automatic models using integrated transmission cooler fittings.

On a 1998 Navara, the radiator sheds heat from the coolant after it’s circulated through the block and head. It works with the thermostat, water pump, viscous fan or electric fan, cap and overflow bottle to hold a steady operating temperature. Keeping it healthy helps avoid warped heads, blown gaskets and frustrating roadside overheats, especially when towing or crawling up a hot Kiwi or Aussie hill in summer.

As part of regular servicing, it’s smart to flush and refill the coolant every 2–3 years or around 40,000–60,000 kilometres, using a quality ethylene glycol coolant that’s compatible with alloy components and meets Nissan specs. They’ll want to avoid tap water with high mineral content
