Engine Coolant Temperature Sensor — 3/8-18 NPTF thread, 2 terminals Key benefits - Accurate temperature feedback: Provides reliable engine coolant temperature readings for the gauge and engine control systems to help maintain proper engine performance, emissions, and cooling fan control. - OE-standard manufacturing: Built with modern tooling to meet original equipment standards for fit, form, and function. - Durable construction: Replacement designed to the same specifications and with materials that are more durable than the OEM part, improving longevity and resistance to corrosion and vibration. - Plug-and-play direct fit: Direct replacement that installs like the factory unit with the specified 3/8-18 NPTF thread and two electrical terminals — no modification required. Important attributes - Function: Measures coolant temperature and delivers an electrical signal to the vehicle’s gauge and engine control systems. - Compatibility: Intended for applications that require a 3/8-18 NPTF threaded coolant temperature sensor with two terminals. Confirm thread size and terminal count against the vehicle’s original sensor before ordering. - Thread size and sealing: 3/8-18 NPTF (dry seal thread standard for many cooling system sensors). - Electrical connection: Two-terminal design compatible with systems that use a dual-terminal coolant sensor. - Performance and reliability: Manufactured to OE standards for consistent readings, fitment, and long-term operation under typical engine bay conditions. Practical use scenarios - Replace a failed sensor when the temperature gauge reads erratically, the engine computer shows a coolant temperature fault, or cooling fans do not engage as expected. - Install during cooling system service or engine repairs to ensure the replacement matches factory specifications and restores proper temperature sensing. - Use as preventive maintenance on high-mileage vehicles to avoid intermittent faults and improve long-term reliability. What you get - One direct-fit engine coolant temperature sensor with 3/8-18 NPTF thread and 2 terminals, manufactured to OE standards and designed for straightforward installation and dependable performance.
