Vehicle Fitment

⚠️ Important: This thermostat housing is specifically for the 3.0L V6 diesel engine (TDV6 / SDV6 / 306DT). Not for petrol, 2.0L Ingenium diesel, or 5.0L V8 variants. For 3.0L V6 supercharged petrol engines, a different thermostat (LR121420) is required.

Signs of Failure

• Engine overheating – thermostat stuck closed, restricting coolant flow

• Engine running too cool / slow warm-up – thermostat stuck open, preventing engine from reaching operating temperature

• Fluctuating temperature gauge – irregular coolant temperature readings

• Coolant leaks – visible drips from the thermostat housing area

• Poor heater performance – cabin heater blows cold air when engine is warm

💡 A failed thermostat can cause engine overheating or undercooling, both of which affect fuel efficiency, emissions, and long-term engine reliability.
