Nissan Navara Coolant Malaysia — NP300 YD25
NP300 uses OAT (Organic Acid Technology) long-life coolant. Change every 2 years or 40,000 km. Diesel engines run hotter under load; low coolant level risks serious overheating damage to the YD25 head gasket. Check coolant concentration — should be 50:50 with distilled water for Malaysian climate. Never mix different coolant types.
