104-3007 Temperature Sensor — Cat 3116 3126

This temperature sensor accurately monitors the engine coolant temperature, providing vital data to the engine control unit (ECU) for optimal performance and protection. Manufactured to meet rigorous OEM specifications, it offers reliable readings unlike a faulty sensor which may provide inaccurate or no data. Operators might observe a fluctuating or inaccurate temperature gauge, illumination of the 'check engine' light, or the engine running hotter than normal when this sensor fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing temperature sensor may initially cause the engine temperature gauge to read incorrectly or erratically. If ignored, the ECU may receive false data, leading to improper fuel mixture or fan operation, potentially causing the engine to overheat or run inefficiently. Continued operation with an inaccurate temperature reading risks severe engine damage due to overheating.

Installation Tip

Ensure the sensor port threads are clean and free of corrosion before installation to achieve a proper seal. Do not overtighten the sensor, as this can damage the threads or the sensor body.

Service Note

When replacing the temperature sensor, it is advisable to check the coolant level and condition, and inspect the thermostat for proper operation.
