341-4827 Temperature Sensor — Cat 320E 312E

This is a CAT Temperature Sensor, a crucial device that monitors the engine coolant temperature and transmits this data to the engine control unit (ECU) or instrument panel. Built to OEM standards, it provides accurate readings for optimal engine performance and protection, unlike faulty sensors that can give incorrect temperature information. Operators might observe inaccurate temperature gauge readings, the engine overheating warning light illuminating, or the engine entering a reduced power mode when this sensor malfunctions.

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

An initial symptom of a failing temperature sensor might be an erratic or inaccurate reading on the engine temperature gauge. If ignored, this can lead to the engine running too hot or too cold, impacting fuel efficiency and performance, or triggering unnecessary warning lights. The worst consequence is the engine overheating without adequate warning, potentially causing severe internal damage.

Installation Tip

Ensure the engine coolant is drained to a level below the sensor port before removal to prevent coolant spillage. When installing the new sensor, avoid over-tightening, which can damage the threads or the sensor body.

Service Note

Check the coolant level and condition, and inspect the radiator and fan for proper operation when replacing the temperature sensor.
