Engine Coolant Temperature Sensor — Direct-Fit Replacement Why you need this sensor - Restores accurate engine coolant temperature readings so the engine control unit (ECU) and dashboard gauge get reliable input. - Prevents drivability issues caused by incorrect temperature data, such as poor idle, rich/lean fuel trim, or improper fan operation. - Provides a durable, long-lasting replacement when the original sensor fails or shows intermittent signals. Key benefits - OE-standard design and modern manufacturing: produced with current tooling to meet original equipment specifications for fit and function. - Improved materials and build quality: engineered to the same specifications as the factory unit while using higher-grade materials for better durability and longer service life. - Direct replacement installation: direct-fit form and electrical compatibility allow straightforward installation with no modification required. What it does (function and performance) - Measures coolant temperature and sends an electrical signal to the ECU and instrument cluster. - Supports engine management functions (fuel mixture, ignition timing), temperature gauge accuracy, and radiator fan control. - Delivers consistent, repeatable temperature readings for dependable vehicle performance. Compatibility and fit - Designed as a direct-fit replacement for the factory coolant temperature sensor; matches the original sensor’s size, mounting style, and electrical connector to ensure seamless installation. - Manufactured to meet OE standards so it can be used wherever the vehicle’s original sensor specification calls for a matching part. Key attributes - Function: Accurate coolant temperature sensing and signal transmission to ECU and instruments. - Fit: Direct-fit replacement, matching factory dimensions and connector interface. - Quality: Manufactured to OE standards using modern tooling; improved material durability compared with the OEM unit. - Performance: Reliable, repeatable temperature readings to maintain correct engine management and cooling operations. Typical applications / use scenarios - Replace a failed sensor when the temperature gauge reads inaccurately, the check engine light indicates a temperature sensor fault, or the cooling fan runs continuously. - Preventive maintenance before a long trip or seasonal change: replace an aging sensor to avoid unexpected temperature-related faults. - Repair after coolant contamination or corrosion has caused intermittent sensor signals, restoring stable engine performance and consistent fan control. What to expect at installation - Plug-and-play fitment with the same connector type and mounting as the factory unit. - No vehicle modifications required; install using standard hand tools following vehicle manufacturer torque recommendations. - Immediate improvement in temperature reporting and related engine control responses once installed. If your vehicle’s coolant temperature sensor is failing or you want a durable direct replacement built to OE standards, this sensor provides accurate temperature readings, reliable performance, and a straightforward install.
