Vehicle Fitment

Jaguar Applications (Cross-Reference):

• for Jaguar XF, XJ, XE, F-TYPE, F-PACE – 3.0L / 5.0L supercharged petrol 

⚠️ Important: This thermostat unit is specifically for supercharged petrol engines – 3.0L V6 (AJ126) and 5.0L V8 (AJ133). Not for naturally aspirated or diesel engines. Fitment varies by model year and VIN range – verify before ordering.

Signs of Failure

• Engine overheating – thermostat stuck closed, restricting coolant flow

• Engine running too cool – thermostat stuck open, preventing engine from reaching operating temperature

• Poor fuel economy – rich mixture due to engine not reaching operating temperature 

• Coolant leaks – visible drips from thermostat housing area

• 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 units are VIN‑, engine‑, and model‑year‑specific. Variations in engine type (3.0L vs. 5.0L supercharged), production date, and VIN range (e.g., from JA000001) affect fitment. 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. Always install with the 'jiggle pin' bleed valve at 12 o'clock when possible .
