That signal is important for fuel control, fan operation, and temperature-related engine protection. This part number 013113021 is built as a standard replacement and follows the physical dimensions commonly required in OE-style service applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 32250) for the same application. It also cross-references Four Seasons (e.g., 37465) for the same application. For Mercedes-Benz E-Class and Mercedes-Benz C-Class service jobs, confirming the thread, terminal count, and mounting style is the key step before installation.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIncorrect coolant temperature readings on the dash or scan tool\u003c\/li\u003e\n\u003cli\u003eCooling fan operation that does not match engine temperature\u003c\/li\u003e\n\u003cli\u003eHard starting or drivability issues tied to temperature input\u003c\/li\u003e\n\u003cli\u003eEngine management faults related to coolant temperature signal loss\u003c\/li\u003e\n\u003cli\u003eReplacement of a worn or failed coolant temperature sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the connector style, 1-pin terminal count, and M14 x 1.5 thread before installation. The sensor uses a bolted mounting style and a 19 mm wrench or spanner size. Because coolant system components can be hot and pressurized, allow the engine to cool fully before service and follow the vehicle manufacturer’s procedure for coolant loss and refill.\u003c\/p\u003e\u003cp\u003eAssy\/Disassy by Qualified Personnel Required.
