3422924 Sender As- Temperature — Cat 307C 307D

This is a temperature sender that monitors engine coolant or oil temperature and transmits this data to the machine's electronic control unit (ECU). It is manufactured to meet stringent OEM quality standards, ensuring accurate readings that differentiate it from a worn sender exhibiting drift or inaccuracy. Operators may observe erratic temperature gauge readings, a persistent high-temperature warning light, or the engine entering a reduced power mode due to faulty temperature data.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

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

Failure Symptoms

The first sign of a failing temperature sender is often inaccurate or fluctuating temperature gauge readings. If left unaddressed, the machine's ECU may receive incorrect data, leading to reduced engine performance or unnecessary warning lights. Continued operation with a faulty sender risks the engine operating outside its optimal temperature range, potentially causing premature wear.

Installation Tip

Before installing the new sender, ensure the engine block threads are clean and free of debris to guarantee a proper seal. Avoid overtightening the sender, as this can damage the threads in the engine block or the sender itself.

Service Note

Inspect the engine's cooling system for leaks and ensure the coolant level is correct when replacing the temperature sender.
