Product Details

This NTK coolant temperature sensor is used to report engine coolant temperature to the vehicle’s control systems, helping the ECU manage fuel delivery, ignition timing, cooling fan operation, and temperature-related diagnostics. It is a direct-fit style replacement for many BMW 320i, 328i, 535i, X5, X6, M3, M5, and related models across the 1997-2018 range, including select Rolls-Royce Ghost and Phantom applications. Part number EF0083 is also referenced in aftermarket catalogs for similar OE applications where the connector style and terminal layout match.

Compatible With BMW 320i, BMW 328i, BMW 535i, BMW X5, BMW X6, BMW M3, BMW M5, and select Rolls-Royce models across the listed fitment range. Fits 2012-2018 BMW 320i, 2012-2016 BMW 328i, 2012-2016 BMW 535i, 2014-2017 BMW X5, and 2011 Rolls-Royce Ghost where the catalog notes match the application.

Common Issues This Sensor Can Help Resolve

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running when the engine is cold or hot
• Cooling fan operation that does not match engine temperature
• Check engine light related to coolant temperature sensor faults
• Fuel mixture or drivability problems caused by inaccurate temperature input

Installation Notes and Tips

Verify connector shape, terminal count, and application notes before installation. This sensor uses a rectangular female connector with blade terminals and does not include a wiring harness. On some BMW applications, the sensor location may be on the cylinder head, water pump, thermostat housing, or return pipe, so confirm the exact mounting point for your vehicle before removal and replacement.

Part number EF0083 should be matched to the vehicle’s year, make, model, and engine configuration using the fitment data. For BMW and Rolls-Royce cooling system repairs, confirm the original sensor style and connector orientation before installation.
