141-4158-1414158 Temperature Sensor 141 4158 14 — Cat G3508 3508B

This temperature sensor is an engine component that accurately measures coolant temperature and transmits this data to the engine control module (ECM). Manufactured to meet precise OEM specifications for accuracy and durability, it ensures reliable readings unlike a faulty sensor. Operators may observe inaccurate temperature gauge readings, unexpected fan operation, or engine derating if 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 incorrect reading on the engine temperature gauge. If the sensor fails completely, the ECM may not receive any temperature data, potentially leading to engine derating or shutdown to prevent overheating. Inaccurate temperature readings can also cause inefficient fuel combustion and increased emissions.

Installation Tip

Ensure the engine is completely cool before attempting to remove the old sensor to avoid burns. Do not overtighten the new sensor, as this can damage the threads in the engine block or manifold.

Service Note

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