Detailed Product Information

This coolant temperature sensor reports engine temperature data to the ECM so the control system can manage operating functions based on coolant conditions. In earlier vehicle systems, coolant temperature input was also used to shut off the compressor and reduce the risk of compressor damage. Global Parts 1712598 is listed for 1983-1990 Jeep applications with the specified thread and terminal configuration.

This part cross-references Four Seasons 37889 for the same application.
