Nissan Serena Radiator Malaysia
Serena C27 radiator generally reliable. Common: expansion tank cap seal seeping at 60,000+ km. Full radiator replacement uncommon before 150,000 km. S-Hybrid stop-start cycling increases thermal stress. Flush coolant at 60,000 km to prevent scale buildup.

- No known radiator-CVT contamination issue on C27 (unlike T32 X-Trail)
- Check radiator condition every 20,000 km — KL traffic heat stresses radiator plastic
- Clean radiator fins every 20,000 km — bugs and debris reduce cooling efficiency
- Coolant flush every 20,000 km — fresh coolant prevents corrosion in radiator passages
