• Connector Type: Standard automotive 2‑pin plug compatible with Volvo, Renault, Ford, and other OEM systems
• Material: High‑temperature resistant plastic housing; stainless steel sensor element
• Compliance: Meets ISO/TS 16949 quality management requirements for automotive components

Vehicle Compatibility

The V95-72-0012 is engineered to fit a wide range of vehicles, particularly those from the following manufacturers and model series:

• Volvo: S40 I (644) 1999‑03 to 2003‑12; 850 Break; 960 II; 73110 series
• Renault: Laguna Safrane; 850 Estate; 9186486 series
• Ford: Various models sharing the same coolant temperature sensor architecture
• Other OEMs: Any vehicle that uses a two‑pole thermistor with a 10 kΩ to 1.5 kΩ resistance range within the specified temperature limits

Because the sensor’s electrical characteristics are standardized, it can be swapped across many platforms without requiring ECU reprogramming.

Installation Guide

1. Preparation: Ensure the engine is cool to avoid burns. Disconnect the negative battery terminal to eliminate any electrical hazard.
2. Remove Old Sensor: Locate the existing coolant temperature sensor in the engine bay, usually mounted on the upper cylinder head or near the thermostat housing. Use a suitable socket or wrench to unscrew the sensor. Carefully detach the wiring connector.
3. Install New Sensor: Align the V95-72-0012 with the mounting hole and screw it in place until snug. Reconnect the two‑pin plug, ensuring a firm connection. Verify that the cable is not twisted or pinched.
4. Reboot ECU: Reconnect the battery and start the engine. Allow it to reach normal operating temperature; the ECU will automatically calibrate using the new sensor’s readings.

Operational Benefits

• Enhanced Engine Protection: By providing precise coolant temperature data, the sensor helps prevent overheating and allows the ECU to adjust cooling fan speed accordingly.
• Improved Fuel Efficiency: Accurate temperature feedback enables optimal fuel mixture calculations, reducing fuel consumption.
• Reduced Emissions: Proper engine temperature management leads to cleaner combustion and lower exhaust emissions.
• Long‑Term Reliability: The robust construction resists corrosion and mechanical shock, ensuring consistent performance over many years of service.

Maintenance Tips

Although the V95-72-0012 is designed for minimal upkeep, regular checks can extend its lifespan:

• Visual Inspection: Periodically examine the sensor housing and cable for cracks, discoloration, or signs of wear.
• Connector Cleanliness: Keep the two‑pin plug free from dirt and corrosion. Use a contact cleaner if necessary.
• Coolant Quality: Maintain proper coolant mixture and level; contaminated coolant can affect sensor accuracy.
