Key Features

• Engine coolant temperature sensor with 2 blade terminals
• 1 female rectangle connector for a secure electrical connection
• Threaded nut mounting style for proper installation
• No wiring harness included
• Package includes the engine coolant temperature sensor and instruction sheet
• Delphi TS10270 replacement part number for OE-style service

Detailed Description

The Delphi TS10270 engine coolant temperature sensor monitors coolant temperature and sends that signal to the vehicle’s engine management system. Accurate temperature input is important for fuel delivery, idle quality, cooling fan operation, and overall drivability. This sensor is a strong match for BMW 328i coolant temperature sensor replacement needs, BMW X5 coolant temperature sensor service, and Land Rover Discovery temperature sensor applications where the original sensor uses a threaded nut mount and a 2-terminal blade connection.

This part cross-references Beck/Arnley 158-0792 for the same application. Delphi’s OE background helps ensure the sensor reflects the fit, form, and function expected in many BMW and Land Rover cooling system repairs.

What It Helps Solve

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting, rough idle, or poor cold-engine operation
• Cooling fan behavior that does not match engine temperature
• Check engine lights related to coolant temperature signal faults
• Driveability issues caused by inaccurate engine temperature input

Installation Notes and Tips

• Verify connector shape, terminal count, and mounting style before installation.
• Inspect the connector and wiring for corrosion, looseness, or heat damage.
• Confirm the sensor location on the cylinder head or water pump, as listed for the vehicle.
• Follow the included instruction sheet and use the correct torque procedure for the threaded nut mount.
• Clear diagnostic trouble codes after installation and verify temperature readings with a scan tool.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed with top automakers. TS10270 reflects that OE-focused approach for dependable cooling system service on covered BMW and Land Rover applications.
