Engine Coolant Temperature Sensor Overview

The VEMO engine coolant temperature sensor, part number V25-72-0046, is a threaded screw-in replacement with a 2-pin connector and an included seal ring. It is built with an M12 x 1.5 thread and an aluminum housing for applications that require a direct-fit temperature signal sensor.

Compatible with a wide range of Mazda, Ford, Mercury, Lincoln, and Land Rover applications, this sensor supports accurate coolant temperature reporting for vehicles such as the Mazda 3, Ford Explorer, and Mazda MX-5 Miata. The V25-72-0046 part number is used across multiple fitments, making it a practical match when the original sensor uses the same connector and thread specification.

Key Features

• Threaded screw-in design with M12 x 1.5 thread size
• 2-pin electrical connection for sensor signal transfer
• Aluminum housing construction
• Includes seal ring for the mounting interface
• Compact sensor body with grey housing finish

Detailed Product Description

VEMO V25-72-0046 is an aftermarket engine coolant temperature sensor engineered for direct replacement applications that use a threaded mounting style and a 2-pin connector. The sensor body measures 56.6 mm in length and 18.96 mm in height and width, with a lightweight design that follows the original-style fitment requirements listed for many Mazda, Ford, Mercury, Lincoln, and Land Rover models. The V25-72-0046 part number appears in fitments for the Mazda 5, Mazda 6, Ford Fusion, Ford Ranger, and Ford Explorer, among others.

This sensor is specified with a seal ring and M12 x 1.5 thread, which helps match the original mounting interface on supported vehicles. It is a practical replacement choice when the existing coolant temperature sensor uses a screw-in design and a 2-pin plug.

Common Issues This Part May Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running caused by inaccurate temperature input
• Cooling fan operation that does not follow engine temperature correctly
• Check engine light concerns related to coolant temperature sensor performance
• Sensor leakage at the threaded mounting point

Installation Notes and Tips

Verify the connector style, thread size, and mounting style before installation. This part fits applications listed with a threaded/screw-in sensor design, M12 x 1.5 thread, and 2-pin connector. On supported vehicles such as the Mazda 3 and Ford Explorer, confirm the engine-specific notes in the fitment table, including VIN or build-date restrictions where shown.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
