⚠️ Important: This thermostat assembly is specifically for the 2.0L petrol engine – not for diesel or 3.0L/5.0L variants.

Signs of Failure

• Engine overheating – thermostat stuck closed, restricting coolant flow

• Engine not reaching operating temperature – thermostat stuck open, preventing proper warm-up

• Coolant leaks – visible drips from the thermostat housing area

• Poor fuel economy – engine running below optimal temperature

• Check engine light – cooling system-related DTCs

💡 Thermostat stuck open is the most common failure – coolant flows constantly, preventing the engine from reaching operating temperature, resulting in poor fuel economy and potential catalytic converter damage.

Critical – Verify Your VIN Before Ordering

Thermostat assemblies are VIN- and engine-specific. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. When replacing the thermostat, inspect all cooling system hoses and connections for wear. Replace coolant with OEM-specified fluid at the correct mixture ratio after installation and bleed the cooling system thoroughly to remove air pockets.
