Veratron Coolant Temperature Sensor - 40°C to 120°C - M15 x 1.5 Thread

The Veratron Coolant Temperature Sensor with M15 x 1.5 thread is a precision instrumentation component essential for accurate engine management and thermal monitoring in modern automotive systems. This sensor bridges the gap between your engine's cooling system and your vehicle's onboard diagnostics, providing real-time temperature data that governs fuel injection timing, ignition advance, and cooling fan operation.

Whether you're tuning a modified engine, diagnosing cooling system issues, or replacing a failed OEM sensor, the Veratron unit delivers the reliability demanded by both daily drivers and performance enthusiasts. This coolant temperature sensor operates across a 40°C to 120°C measurement range, covering typical engine operating windows from cold start through sustained high-load conditions. The M15 x 1.5 metric thread design ensures direct bolt-in compatibility with European and many Asian engine blocks that follow ISO standard cooling jacket boss dimensions.

The sensor utilizes thermistor technology to convert coolant temperature into a precise electrical signal; as coolant temperature rises, sensor resistance changes proportionally, allowing the engine control module to make millisecond adjustments to fuel mixture and ignition parameters. This direct relationship between temperature and electrical output is critical for maintaining optimal combustion efficiency and preventing knock or lean-running conditions that damage pistons and valves. Mechanics and engine tuners will find this sensor invaluable for ensuring their engines operate at peak performance.
