Nissan Serena Coolant Malaysia
Serena C27 uses Nissan long-life coolant. First change at 60,000 km or 4 years, then every 2 years. Expansion tank cap seal is a minor seep point — replace cap if coolant drops with no visible leak. Never top up with tap water. S-Hybrid stop-start cycles mean the cooling system works harder than in a conventional car.
Serena Coolant Maintenance
- MR20DD S-Hybrid: Nissan Long Life Coolant — flush every 80,000 km
- Check coolant level monthly — MPV loaded = more heat generation
- S-Hybrid battery generates additional heat — ensure adequate coolant level at all times
- Do not mix coolant colours — blue and orange/pink chemistries are incompatible
