435-4932 Temperature Sensor — Cat 316F 318F

This temperature sensor accurately measures the coolant temperature within the engine's cooling system, providing critical data to the engine control module (ECM). It ensures the ECM can regulate fan speed, fuel delivery, and ignition timing for optimal operating temperature and efficiency. A faulty sensor may cause inaccurate temperature readings, leading to engine overheating, reduced power, or increased fuel consumption, often indicated by a warning light or erratic gauge readings.

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

An inaccurate temperature sensor may cause the engine temperature gauge to read incorrectly, fluctuate erratically, or remain at a fixed point. This can lead to the engine running too hot or too cold, impacting performance and fuel efficiency. Persistent incorrect readings can result in engine damage due to overheating or inefficient operation.

Installation Tip

Ensure the sensor's mounting port is clean and free of any coolant residue or debris before installation. Do not use thread sealant on sensors that rely on a metal-to-metal seal for proper electrical contact.

Service Note

Inspect the engine coolant level and condition, and check the radiator and fan for proper operation when replacing the temperature sensor.
