A failing thermostat in the Haval H6 can manifest through various symptoms:

Engine Overheating: If the thermostat is stuck closed, it prevents coolant from circulating, causing the engine to overheat.

Erratic Temperature Gauge Readings: Fluctuating o r inconsistent readings on the temperature gauge can indicate a malfunctioning thermostat.

Poor Fuel Economy: An engine that doesnt reach its optimal operating temperature due to a stuck-open thermostat can lead to increased fuel consumption.

Coolant Leaks: A damaged thermostat can cause pressure build-up, leading to leaks in the cooling system.
