Key Features

• Engine coolant temperature sensor for electronic temperature feedback
• 2-terminal design on listed applications
• Used in radiator or water outlet locations on select vehicles
• Supports ECM input for cooling system and A/C control logic
• Global Parts part number 1712577

Detailed Description

Global Parts 1712577 is an engine coolant temperature sensor built for vehicles that use a two-terminal coolant temp signal to inform the engine control module. On modern systems, that signal helps the ECM manage A/C operation and cooling decisions; on earlier designs, it can directly interrupt compressor operation to reduce the risk of compressor damage. This makes 1712577 a practical replacement when the original sensor is no longer reporting temperature accurately.

Compatible With select Chevrolet Cruze, Chevrolet Malibu, Chevrolet Sonic, Chevrolet Impala, Chevrolet Spark EV, Chevrolet Malibu Limited, Chevrolet Blazer, Chevrolet Camaro, Cadillac ATS, Cadillac CT6, Buick Encore, and related applications listed below. Part number 1712577 is also referenced by Four Seasons 37887 and UAC SW11532C.

What It Helps Address

• Incorrect coolant temperature readings
