Engine coolant temperature sensor that provides accurate, reliable temperature feedback to the engine control system and dashboard gauge. Designed to help the vehicle maintain correct engine temperature, optimize fuel delivery and ignition timing, and control cooling fan operation. A straightforward replacement part for a failed or inaccurate factory sensor. Key benefits Improves engine performance and fuel economy by supplying accurate coolant temperature data to the ECU. Prevents engine overheating and reduces the risk of longterm damage by enabling timely coolingfan activation and driver warnings. Restores correct temperature readings on the dash and eliminates erratic gauge behavior or incorrect temperaturerelated diagnostic codes. Simple installation reduces downtime — can be installed by a DIYer or professional technician with basic hand tools. Key attributes Functionality: Measures engine coolant temperature and converts it to an electrical signal (resistance/voltage) compatible with the vehicle's engine control unit and dashboard instruments. Compatibility: Intended as a replacement sensor for compatible vehicles. Verify fit by comparing connector type, thread size, and part number before . Size and form: Compact, enginemounted design that fits standard sensor mounting locations. Threaded body for secure installation in the coolant passage or thermostat housing. Material and construction: Corrosionresistant metal and temperature plastic components with a sealed electrical connector to withstand engine bay conditions. Performance: Fast response to temperature changes and stable output for consistent ECU readings; designed for continuous operation in the thermal and vibration environment of the cooling system. Typical applications / use cases Replacing a failed coolant temperature sensor that causes overheating warnings, poor idling, or a check engine light related to temperature sender faults. Routine maintenance or when diagnosing temperaturerelated drivability issues such as hard starting, rich/lean running while cold, or fans not engaging. Use in garages and shops for diagnostics and reliable replacement during coolingsystem service on compatible passenger cars, light trucks, or SUVs. Installation notes and compatibility check Before installing, compare the sensor's connector shape, pin count, thread style, and overall length with the original unit. Follow vehicle manufacturer torque recommendations and threadsealing practices where applicable to avoid leaks. After installation, clear any diagnostic trouble codes and confirm correct gauge/ECU readings during warmup. Quality and reliability Built to meet common automotive electrical and thermal performance expectations for engine temperature monitoring. Intended to deliver longterm, stable operation when installed and used according to vehicle manufacturer guidelines. Verify compatibility with your vehicle's make, model, and original part number before to ensure a direct and reliable fit.
