⚠️ Important: This thermostat unit is confirmed for the 3.0L V6 supercharged petrol engine (AJ126) in the models listed above. Confirm your engine type and VIN before ordering.

Signs of Failure

• Engine overheating — thermostat stuck closed, restricting coolant flow

• Engine running too cool — thermostat stuck open, preventing proper warm-up

• Coolant leaks — visible drips from the thermostat housing area

• Erratic temperature changes — unstable temperature gauge readings

• Poor fuel economy — engine running below optimal temperature

💡 Known Failure Issue: The factory plastic thermostat housing on the AJ126 engine is a documented high-failure component. The plastic housing is prone to cracking, warping, and premature failure under heat and pressure. If not addressed promptly, coolant loss can cause catastrophic engine damage including warped cylinder heads and blown head gaskets. Upgraded aluminium versions are strongly recommended for enhanced durability and to prevent repeat failure.

Critical – Verify Your VIN Before Ordering

Thermostat units are VIN-, engine-, and model-year-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. It is recommended to replace the water pump and oil cooler connector at the same time for a complete cooling system service. Refill with OEM-specified coolant at the correct mixture ratio and bleed the cooling system thoroughly to remove air pockets. Consider upgrading to the aluminium version for enhanced durability and to prevent repeat failure.
