Hella Engine Coolant Temperature Sensor

The Hella Engine Coolant Temperature Sensor (also called an ECT sensor, coolant temp sensor or water temperature sensor) monitors engine coolant temperature and sends that data to the engine control unit. The ECU uses the signal to manage fuel injection, ignition timing, idle speed and cooling fan operation, and to drive the dashboard temperature gauge or warning light.

Key Features:

• Temperature-sensitive thermistor element that gives accurate coolant readings for engine management
• Built to meet OE specifications for fit, form and function
• Sealed construction resists coolant, heat, vibration and under-hood contaminants
• Helps support smooth starts, steady idle, good fuel economy and correct emissions control
• Backed by Hella's long record as an original equipment supplier to major vehicle manufacturers

A failing coolant temperature sensor can cause hard starting, rough idle, poor fuel economy, black smoke, overheating or cooling fan problems, and it can set a check engine light. Replacing it with a quality Hella sensor helps restore accurate engine temperature monitoring and reliable engine performance. Select the specific part number below for your application.
