Engine Coolant Temperature Sensor — 1/8-27 NPTF thread, 2 terminals What it does - Measures engine coolant temperature and provides the electrical signal used by the engine control system, temperature gauge, and fan or thermostat control. Key specifications - Thread: 1/8-27 NPTF - Electrical: 2 terminals - Function: Direct replacement engine coolant temperature (ECT) sensor - Fitment: Designed as a direct-fit replacement for the factory unit Why you need it - Restores accurate coolant temperature readings to prevent misdiagnosis of overheating or cold-run conditions. - Replaces a failed or intermittent sensor to resolve check-engine codes related to coolant temperature and improve engine performance and fuel management. - Ensures reliable fan control and proper gauge operation so you can drive with confidence. What makes this sensor stand out - Built to OE standards using modern tooling for consistent manufacturing quality and dependable performance. - Constructed from durable materials that meet original specifications and are selected to resist corrosion and wear better than typical OEM components. - Direct-fit design installs like the factory unit—no modification required—reducing install time and the risk of sealing or electrical issues. Benefits at a glance - Accurate, consistent temperature signals for stable engine control and gauge readings - Durable construction for longer service life and improved resistance to coolant and vibration - Easy, bolt-on replacement that maintains original fit and function - Manufactured to modern quality controls for reliable repeatability Common applications / use scenarios - Replace a faulty ECT sensor to clear a P0128 or P0117/P0118 trouble code and restore correct engine warm-up behavior. - Install during thermostat replacement or coolant system service to ensure all temperature-related components are new and compatible. - Use when the temperature gauge reads erratically or the radiator fan is running continuously/intermittently due to incorrect temperature signaling. Installation notes - Thread size: 1/8-27 NPTF — confirm this matches the original sensor thread on your vehicle before ordering. - Electrical connection: 2-terminal plug — verify connector compatibility. - Install with proper thread sealant compatible with coolant systems if required; torque to vehicle manufacturer specifications. Manufacturing and quality - Produced with modern tooling and production controls to meet OE standards for form, fit, and function. - Replacement component engineered to the same specifications as the original while using improved materials for enhanced durability. If your vehicle requires a 1/8-27 NPTF, 2-terminal engine coolant temperature sensor as a direct replacement for the factory unit, this part provides a reliable, OE-standard solution.
