FAQs

How do I know if my coolant temperature sensor needs replacement?

Common signs include the check engine light, inaccurate temperature gauge readings (engine running too hot or too cold), poor fuel economy, and rough idling.

What is the thread size of this sensor?

The thread size is M14 x 1.5.

What does the 2-pin connector signify?

A 2-pin connector typically indicates that the sensor provides temperature readings for both the engine control unit (ECU) and the dashboard temperature gauge.

Can I use this sensor on any Mercedes-Benz model?

No, this sensor is designed for specific Mercedes-Benz models. Always use the vehicle compatibility tool or consult with us to ensure proper fitment for your particular car.

What OEM part numbers does this sensor replace?

This sensor replaces OEM part numbers 0095423517 and A0095423517.

Does this sensor come with a gasket or sealant?

Typically, sensors like this do not include separate gaskets. Thread sealant may be recommended during installation, depending on the vehicle manufacturer's specifications. Please check the product packaging or consult your vehicle's service manual.

Troubleshooting

Check Engine Light is on after installation

Ensure the sensor is correctly installed and the electrical connector is securely attached. Verify that the correct part number was used for your vehicle. Check for any coolant leaks around the sensor housing.

Inaccurate temperature readings on the gauge

Confirm the sensor is fully seated and tightened correctly. Check the wiring harness for any damage or corrosion. If issues persist, the new sensor may be faulty, or there might be an underlying issue with the vehicle's wiring or gauge.

Engine overheating or running too cool

While often related to the thermostat or coolant level, an inaccurate temperature sensor reading can contribute. Re-verify sensor installation and connectivity. If the problem persists, consider other components of the cooling system.
