261-6848 Exhaust Gas Temperature Sensor — Cat 3516B 3512B

This is an Exhaust Gas Temperature (EGT) Sensor, crucial for monitoring exhaust gas temperatures to optimize engine performance and prevent overheating. It is manufactured to meet OEM standards for accuracy and durability, providing reliable readings unlike a faulty sensor that may give incorrect data. Operators might notice engine derating, increased exhaust temperatures displayed on the dash, or diagnostic trouble codes related to exhaust temperature if this sensor fails.

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

The engine control module may report high exhaust gas temperatures or fail to regulate engine power correctly, potentially leading to reduced performance. Continued operation with a faulty sensor can risk engine damage due to uncontrolled high temperatures.

Installation Tip

Ensure the exhaust manifold threads are clean and free of carbon buildup before installation; use anti-seize compound specifically designed for high-temperature exhaust applications.

Service Note

Inspect the exhaust system for leaks and check the engine's cooling system for proper operation when replacing the EGT sensor.
