Preventive Tips:

Use High-Quality Coolant: Always use high-quality coolant that meets the manufacturer’s specifications. Cheap o r diluted coolant can cause deposits to form, which can clog the thermostat o r the cooling system.
Regular Coolant Flush: Flushing the coolant system every 30,000 km ensures that the coolant remains clean and free from contaminants that could cause thermostat failure.
Inspect the Cooling System: During routine maintenance, have the entire cooling system including radiator, hoses, and water pump inspected to avoid pressure o r flow issues that could affect the thermostat.
Monitor the Temperature Gauge: Keep an eye on the temperature gauge during long drives o r in extreme weather conditions. If it starts fluctuating, get the thermostat checked promptly.
