Product Details

Holstein Parts 2CTS0037 is used in cooling-system temperature feedback circuits that report engine coolant temperature to the vehicle control system. The sensor configuration matches applications that call for a rectangular connector and two flat pins, including Ford Explorer and Mercury Mountaineer fitments, as well as threaded/screw-in applications on Ford Fusion and Mercury Milan models. This part number, 2CTS0037, also appears in interchange listings for several OE-style replacement references, making it a practical choice when replacing a failed coolant temperature sensor on the correct engine and connector style.

• Sensor connector or terminal wear at the original unit

Installation Notes

Verify connector shape, terminal count, and thread style before installation. This Holstein Parts sensor uses a female rectangular connector with blade terminals and does not include a wiring harness. On listed Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer applications, confirm the near-thermostat or aluminum-housing location before replacement. On Ford Fusion, Mercury Milan, and Jaguar S-Type applications, confirm the threaded/screw-in style and thread size match the original sensor.
