Description

The ACDelco 15326386 OE Engine Coolant Temperature Sensor is manufactured to be the exact original equipment component installed during vehicle production. This ensures it provides the same performance, durability, and service life as the factory part. Constructed from aluminum, this sensor features a 3/8 inch thread size and a 2-pin connector, making it a direct replacement for your vehicle's original component. It is specifically designed for 2001-2010 GM vehicles equipped with the 6.6L Duramax engine, including LB7, LLY, LBZ, and LMM models. By accurately measuring the engine's coolant temperature, this sensor provides critical data to the vehicle's computer, enabling optimal engine performance, fuel efficiency, and emissions control. A functioning coolant temperature sensor is essential for proper engine operation, especially in diesel applications like the 6.6L Duramax.
