Detailed Product Description

The Global Parts 1814540 sensor is used to monitor coolant temperature and transmit that information to the engine control module. Accurate temperature feedback is important for cooling system operation, fuel management, and engine protection. When the sensor signal becomes inaccurate or intermittent, the ECM may receive incorrect data and the vehicle can experience drivability or temperature-control concerns.

Fitment includes 2014 Cadillac XTS, on water outlet, as well as 2011-2012 Chevrolet Spark, 2004-2010 Pontiac Matiz, and 2004-2006 Suzuki Verona. If you are searching for a coolant temperature sensor for 2014 Cadillac XTS on water outlet or a replacement engine coolant temperature sensor for 2011-2012 Chevrolet Spark, part number 1814540 is a direct OE-style option.

What It Helps Address

• Incorrect coolant temperature readings at the ECM
• Cooling system control issues caused by a failing sensor
• Overheating concerns related to inaccurate temperature input
• Check engine light conditions tied to coolant temperature signal faults
• Poor engine management response from unstable sensor data

Installation Notes and Tips
