Hella 009107351 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

This Hella engine coolant temperature sensor is built for BMW cooling system applications that require accurate temperature input for engine management. Part number 009107351 uses a 2-pin NTC sensor design with a bolted mount and included seal for a secure installation.

Compatible With BMW 530i, 540i, 740i, 740iL, 840Ci, 850CSi, 750iL, 850Ci, and 850i applications listed below. The 009107351 sensor is a direct-fit style replacement for vehicles that use an M14x1.5 threaded coolant temperature sensor with a 12V, two-connector configuration.

Key Features

• NTC sensor design for coolant temperature signal input
• 2-pin connector layout for the specified electrical connection
• Bolted mounting style with M14x1.5 thread size
• Includes seal for the sensor installation point
• Rated for 12V systems

Detailed Description

Hella 009107351 is an engine coolant temperature sensor used to report coolant temperature to the vehicle control system. Its NTC sensing element changes resistance with temperature, allowing the engine management system to monitor operating conditions and respond to temperature-related inputs. This part number 009107351 is listed for multiple BMW applications, including 1994-1995 BMW 530i and 540i, 1993-1995 BMW 740i and 740iL, and 1991-1995 BMW 850-series models shown in the fitment data.

This part cross-references Bosch (e.g., 0 280 130 037, 0 280 130 038) for the same application.

What It Is Used For

• Replacing a faulty coolant temperature sensor that sends incorrect readings
• Addressing hard starting or poor cold-engine fueling caused by bad temperature input
• Correcting temperature gauge or engine management signal issues
• Restoring proper coolant temperature reporting to the control system

Installation Notes and Quality

Install only on applications that match the listed connector style, thread size, mounting type, and seal requirement. Verify the sensor port and electrical connection before installation. The fitment data shows BMW applications with either the specified 12V, 2-pin, bolted, sealed configuration or notes marked “All Required,” so confirm the exact vehicle listing before ordering.

Hella supplies temperature sensors for automotive cooling and engine management applications, and this part follows the listed OE-style specifications for the stated fitments.
