Detailed Description

The SKTX104 is an engine coolant temperature sensor used in cooling-system and engine-management circuits. This sensor is listed for Ford Explorer, Ford Ranger, Ford Mustang, Ford Fiesta, Ford Focus, Ford Five Hundred, Ford EcoSport, Explorer Sport Trac, Mazda B4000, and Mercury Mountaineer applications, with fitment notes identifying several connector and sensor styles. Use the fitment notes to confirm the exact terminal or sensor configuration before ordering. The SKTX104 part number also appears in interchange listings, including Standard Ignition TX104 and cross-reference 3L8A12A648BA / TX104X for the same application.

Common Uses

  • Replacing a failed coolant temperature sensor that triggers inaccurate temperature readings
  • Addressing hard starting or rough running caused by incorrect coolant temperature input
  • Correcting cooling fan control issues tied to sensor signal errors
  • Restoring proper engine management data after sensor wear or connector mismatch

Installation Notes

Confirm the year, make, model, and fitment note before installation, especially on applications marked with 2 blade terminal, gray connector, metal sensor, push-in type, or air intake/air outlet tube notes. Match the connector style and sensor design to the vehicle listing to avoid fitment errors. Verify the cooling system is safe to service before removing the existing sensor.

Quality Assurance

SKP catalogs this sensor under a direct replacement application range for multiple Ford, Mazda, and Mercury vehicles. The SKTX104 part number is also referenced by Standard Ignition TX104 and 3L8A12A648BA / TX104X interchange listings.
