Engine Coolant Temperature Sensor for Ford and Lincoln

Holstein Parts 2CTS0039 is an engine coolant temperature sensor built for direct-fit replacement in a wide range of Ford, Lincoln, Jaguar, Land Rover, Mazda, and Mercury applications. It uses a 2-blade terminal design with a rectangular female connector for a secure electrical connection in thermostat housing, radiator, and coolant circuit locations.

Holstein Parts focuses on application-specific replacement sensors, and this Holstein Parts line part is listed across many late-model and earlier Ford cooling-system platforms, including Ford Fusion, Ford Escape, Ford Focus, and Ford Ranger coverage.

Key Features

• Engine coolant temperature sensor for cooling-system temperature monitoring
• Blade terminal type with 2 terminals
• Rectangular female connector for a direct electrical interface
• No wiring harness included
• Used in thermostat housing, radiator, coolant, and water outlet locations depending on application
• Holstein Parts 2CTS0039 cross-references Delphi TS10329 and Standard Ignition TX104 for the same application

Detailed Description

The Holstein Parts 2CTS0039 engine coolant temperature sensor reports coolant temperature to the vehicle’s engine management system so the ECU can manage fuel delivery, idle strategy, cooling fan operation, and temperature-related diagnostics. This sensor is cataloged for many Ford and Lincoln models, along with select Jaguar, Land Rover, Mazda, and Mercury vehicles, making it a practical replacement for common cooling-system service needs. If you are servicing a Ford Fusion, Ford Escape, or Ford Focus, this part number is listed for multiple model years and sensor locations.

Compatible vehicle coverage includes Fits 2018-2019 Ford Escape, thermostat housing sensor; Fits 2015-2017 Ford Focus, located on radiator; Fits 2013-2017 Ford Fusion, and Fits 2013-2017 Lincoln MKZ. Additional coverage includes Ford Ranger, Ford Explorer, Ford Taurus, Ford Transit Connect, and select Land Rover and Jaguar cooling-system applications. Holstein Parts 2CTS0039 is also referenced for Ford Fusion and Ford Ranger service applications where the original sensor uses a 2-blade terminal layout.

What It Is Used For

• Replacing a failed coolant temperature sensor that triggers temperature-related fault codes
• Restoring inaccurate dash temperature readings
• Correcting hard-start, rough-idle, or rich/lean running concerns tied to coolant temperature input
• Addressing cooling fan operation issues caused by incorrect temperature signal data
• Repairing thermostat housing, radiator, or coolant sensor leaks at the electrical sensor location

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. This part uses a rectangular female connector with 2 blade terminals and does not include a wiring harness. On applications such as Ford Fusion, Ford Escape, and Ford Focus, confirm whether the sensor mounts in the thermostat housing, radiator, or coolant passage, and inspect the sealing surface and O-ring condition during service. Always compare the removed sensor to the replacement part number 2CTS0039 before installation.

Quality Assurance

Holstein Parts 2CTS0039 is cataloged as an application-specific replacement sensor for the listed vehicle platforms and cooling-system locations. The part is supported by multiple interchange references, including Delphi TS10329 and Standard Ignition TX104, which helps confirm application matching during parts lookup.
