Detailed Description

This Global Parts coolant temp sensor is engineered to provide the ECM with accurate coolant temperature information so the engine control system can respond correctly to changing operating conditions. The sensor uses a blade terminal design, a single oval female connector, and two male terminals for the specified GM applications.

Part number 1814556 is a practical OE-style replacement for drivers and technicians servicing GM cooling and engine management systems. It is listed for engine block and N/A positions depending on application, so match the vehicle and location carefully before installation.

What It Helps Address

  • Incorrect coolant temperature readings at the ECM
  • Cooling fan operation concerns tied to bad temperature input
  • Overheating warnings caused by a failing sensor signal
  • Hard starting or drivability issues related to temperature data
  • Check engine light conditions associated with coolant temperature sensor faults
