Febi 31539 Coolant Temperature Sensor with Seal and Retaining Spring

The Febi 31539 is a precision-engineered coolant temperature sensor designed to provide accurate engine temperature readings to your vehicle's engine control unit (ECU). This sensor monitors the temperature of the engine coolant and transmits this critical data to ensure optimal engine performance, fuel efficiency, and emissions control.

Key Features:

• Complete assembly includes temperature sensor, seal, and retaining spring for proper installation
• Manufactured to OE specifications for reliable fit and function
• High-quality construction ensures accurate temperature readings across full operating range
• Direct replacement for worn or failed original sensor
• Helps prevent engine overheating and poor fuel economy caused by faulty temperature data

This sensor is essential for proper engine management system operation. A failing coolant temperature sensor can cause rough idle, poor fuel economy, illuminated check engine light, or difficulty starting. The included seal and retaining spring ensure a secure, leak-free installation.
