Nissan Sylphy Radiator Malaysia
Sylphy B17 radiator is generally reliable but plastic tank cracking at the metal-to-plastic joint is possible at 100,000+ km, especially on original radiators not subjected to regular coolant flushes. Signs of radiator failure: coolant level dropping without visible leak (internal weep), drips from the lower tank, or the car running hotter than normal. Malaysia's stop-start traffic causes more thermal cycling stress on the radiator than highway driving. Flush coolant on schedule to prevent mineral scale buildup inside the radiator.
Sylphy 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
