Parts for your 2002 Nissan Navara-Radiator

2002 Nissan Navara Radiator — Purpose, care, and when to replace

Based on the Nissan D22 Navara Factory Service Manual (Cooling System section) and OEM parts catalogues for the D22 platform, the 2002 Nissan Navara is equipped with an engine radiator. Across the KA24DE petrol and the TD27/QD32/ZD30/YD25 diesel options (market-dependent), it uses a crossflow aluminium core with plastic end tanks, and many automatic models integrate a transmission fluid cooler in the lower tank.

The radiator’s job is simple but vital: it dumps engine heat into the airstream so the Navara stays in its comfort zone, whether towing, crawling on a track, or idling on a hot arvo. Coolant absorbs heat in the block and heads, flows through the radiator, and cools as air passes the fins. A healthy radiator keeps temps steady, protects head gaskets, and helps the heater work properly on cold mornings.

• Controls engine temperature for performance and fuel economy
• Prevents overheating under load and in summer conditions
• Supports heater performance and overall cooling system longevity

For servicing, workshops typically pressure-test the system, check the cap, and inspect fins, tanks, and seams. Coolant should meet Nissan specifications
