1254812 Sender As- Temperature — Cat 320B

This is a temperature sender that monitors engine coolant temperature and transmits this data to the engine control unit or dashboard gauge. It is manufactured to meet stringent OEM standards, ensuring accurate readings unlike a worn sender that may provide erratic or no data. Operators may notice a fluctuating temperature gauge, a check engine light, or an engine overheating warning if this sender fails.

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.

Failure Symptoms

An initial sign of failure may be an inaccurate or fluctuating engine temperature reading on the gauge. If left unaddressed, this can lead to the engine management system making incorrect fuel or cooling adjustments. Continued operation with a faulty sender risks engine damage due to undetected overheating.

Installation Tip

Ensure the engine is cool before attempting removal to avoid contact with hot coolant. Do not overtighten the sender into the engine block, as this can damage the threads or the sender itself.

Service Note

Inspect the engine coolant level and condition, and check the integrity of the wiring harness connected to the sender.
