Veratron Coolant Temperature Sensor - 40°C to120°C - 3/8 -18 NPTF Thread

The Veratron Coolant Temperature Sensor with 3/8 -18 NPTF thread is an OEM-grade engine monitoring component designed for accurate coolant temperature measurement across the 40°C to 120°C operating range. This sensor serves as a critical input device for engine management systems, allowing your vehicle's computer to optimize fuel injection timing, ignition advance, and cooling fan activation based on real-time thermal data.

Veratron's 323-801-001-007N sensor employs a thermistor-based design that translates thermal expansion into a variable resistance signal, typically outputting between 5 ohms at 120°C and 188 ohms at 40°C depending on engine specifications. The 3/8 -18 NPTF thread provides a secure, leak-proof installation into engine block coolant passages or thermostat housings, with the compact 1 x 1 x 2 inch form factor allowing integration into tight engine bay configurations.

Veratron's marine-grade construction ensures corrosion resistance and thermal stability, critical factors for long-term reliability in environments where coolant chemistry and operating temperatures demand durability. Mechanics and enthusiasts upgrading cooling systems, swapping engine management systems, or troubleshooting temperature-related drivability issues will find this sensor to be an essential component for optimal performance.
