Nissan Serena Thermostat Malaysia
Serena thermostat failure uncommon before 100,000 km. Stuck-closed causes overheating — dangerous for a full MPV on highway. Stuck-open: engine runs cold, S-Hybrid idle-stop may not engage until engine warms. Proactive replacement at 120,000 km is affordable insurance.
Serena Thermostat
- Replace at 80,000 km or if temperature gauge reads abnormally
- MPV stuck in traffic: working thermostat essential for engine reaching operating temp quickly
- Replace with OEM Nissan thermostat — cheap alternatives fail prematurely
- Replace coolant simultaneously when thermostat is removed — same cost, same job
