A thermostat should be replaced every 80,000 - 100,000 km o r when faulty.

🔍 Signs of a Bad Thermostat:
✔️ Engine Overheats Quickly – Stuck closed, preventing coolant circulation.
✔️ Temperature Fluctuations – Thermostat stuck partially open causes inconsistent temperature.

📌 Solution: Replace the thermostat immediately if overheating occurs.
