Delphi TS10263 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Mercedes-Benz

The Delphi TS10263 engine coolant temperature sensor provides direct temperature input for the engine management system. It is built with OE-focused engineering and is a direct replacement for many Mercedes-Benz applications from 1988-1995, including E420, S500, and 300E models.

• Engine coolant temperature sensor for Mercedes-Benz cooling system monitoring
• Pin terminal type with 1 round female connector and 4 male terminals
• Threaded nut mounting for secure installation
• Wiring harness not included
• Package contents: engine coolant temperature sensor and instruction sheet
• Delphi TS10263 replacement part for OE-style fit and function

OE-Style Temperature Signal Control

Delphi draws on more than a century of OE experience, and that background is reflected in the TS10263 coolant temperature sensor. This sensor reports engine coolant temperature to the vehicle control system, helping maintain accurate fuel and ignition strategy, stable idle behavior, and proper temperature-based engine management. It is a strong match for Mercedes-Benz 190E, 300E, 300SE, 500SL, and related models that require a threaded-nut style coolant temperature sensor. This part cross-references Beck/Arnley (e.g., 158-0741) for the same application.

Common Replacement Reasons

• Incorrect coolant temperature readings
• Hard starting or rough cold operation
• Unstable idle caused by faulty temperature input
• Check engine concerns related to coolant temperature signal
• Cooling system control issues tied to sensor failure

Installation Notes

Verify connector shape, terminal count, and threaded mounting style before installation. The TS10263 uses a round female connector with four male terminals and does not include a wiring harness. Confirm the sensor location and thread engagement on the Mercedes-Benz engine before tightening, and compare the removed part to the new sensor to ensure the correct OE-style replacement.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and engineering knowledge developed through long-term supplier experience with major automakers. The TS10263 is produced to support dependable temperature signal accuracy and consistent replacement performance.
