The number of coolant temperature sensors in a car can vary depending on the make and model. In the case of the 1.4 petrol turbo Opel Meriva, it typically has two coolant temperature sensors:
Engine Coolant Temperature (ECT) Sensor: This sensor is usually located on or near the engine block and provides the engine control unit (ECU) with information about the temperature of the coolant. It helps the ECU adjust fuel mixture and ignition timing for optimal performance and emissions.
Temperature Sensor for the Cooling Fan: Some vehicles, including the Meriva, have an additional temperature sensor for the cooling fan. This sensor is responsible for activating the cooling fan when the engine reaches a certain temperature to prevent overheating.
You mentioned that you've already changed the one on the top of the engine, which is likely the ECT sensor. If you suspect there may be another sensor related to the cooling fan, it's typically located on or near the radiator or in the coolant hose leading to the radiator.
To be sure about the specific locations and number of sensors in your Meriva, it's advisable to consult the vehicle's service manual or reach out to a dealership or qualified mechanic who can provide precise information for your car's year and model. They can also assist you in identifying and replacing any additional sensors if necessary.

- The main Engine Coolant Temperature (ECT) sensor, which is usually located on or near the engine block (often at the top of the engine on the nearside, which you have already changed).
- A second sensor, often dedicated to controlling the radiator cooling fan, which is usually found on or near the radiator or in the coolant hose leading to the radiator.
The ECT sensor sends temperature data to the engine control unit (ECU) to manage engine performance and emissions, while the fan sensor triggers the cooling fan as needed to prevent overheating.
If you have changed the one on the engine, there is likely another sensor related to the cooling fan elsewhere in the cooling system. For exact locations and confirmation for your specific vehicle year, consulting the service manual or a qualified mechanic is recommended.
