Nissan Navara Radiator Malaysia — NP300 YD25
Diesel radiators are larger than petrol equivalents due to higher heat rejection. The intercooler is a separate unit from the radiator. Check for plastic tank cracks at the radiator end tanks — a common failure on high-mileage diesels. Flush and refill the cooling system every 2 years. Keep the intercooler fins clean to maintain charge air cooling efficiency.
Navara Radiator Maintenance
- Inspect radiator every 60,000 km for leaks, corrosion, and fin damage
- Clean external fins every 40,000 km — KL traffic insects and dust reduce cooling efficiency
- Flush coolant every 80,000 km — prevents internal radiator corrosion
- Plastic end-tank crack = replace whole radiator — do not just seal with stop-leak
