Chery Tiggo 8 Pro cooling system thermostat failure — overheating
Temperature gauge rises above normal operating temperature during sustained highway driving or in slow traffic. The thermostat on the 2.0T engine can stick in the partially closed position, restricting coolant flow. Replacing the thermostat with a genuine Chery unit resolves the overheating. Always check for air locks in the cooling system after thermostat replacement.
