ACDelco Engine Coolant Temperature Sensor Switch

The ACDelco Engine Coolant Temperature Sensor Switch (also called a coolant temp sensor or ECT sensor) monitors engine coolant temperature and sends that data to the vehicle's engine control module. The ECM uses the signal to help manage fuel delivery, ignition timing, cooling fan operation, and temperature gauge readings.

Key Features:

• Designed to give accurate coolant temperature readings for reliable engine management
• Helps support smooth starts, steady idle, and efficient fuel economy
• Helps trigger cooling fan operation at the right time to protect against overheating
• Built from ACDelco's original-equipment-style design and testing standards
• Replaces worn, slow, or failed sensors that can cause hard starting, poor running, or an inaccurate temperature gauge

ACDelco is General Motors' parts brand, and it has a long history of making replacement parts for domestic and import vehicles. Choose the sensor that matches your application to get dependable performance and a straightforward installation.
