Keep your engine's cooling system reporting accurate data with the MotoRad 1TS1230 Coolant Temperature Sensor. Engineered with a precision-machined brass housing for OE-level thermal conductivity, this sensor is designed to deliver dependable temperature readings that help your engine management system perform correctly. MotoRad positions the thermistor to OE-matched specifications, so the sensor outputs parameters your vehicle's computer expects, supporting proper fan cycling, fuel trim, and temperature gauge accuracy. Before reaching your garage, every sensor undergoes extensive testing including salt spray exposure, high and low temperature impact, thermal vibration, durability cycling, static electricity, and micro tension testing—all aimed at confirming performance that meets or exceeds OEM specifications. Manufactured at ISO TS16949 certified facilities, the 1TS1230 fits a range of GM, Isuzu, and Saab applications from 2004-2012. A straightforward one-per-application design makes ordering simple for your coolant sensor replacement.
