268-4360 Water Temperature Sensor — Cat 3054E 3056E

This is a CAT Water Temperature Sensor, which monitors the engine coolant temperature and sends this information to the engine control unit (ECU) or the operator's gauge. It is designed for accurate and reliable readings within the harsh engine environment, unlike a failing sensor that provides inaccurate or no data. Operators may notice the engine temperature gauge reading incorrectly, or the ECU may trigger a warning light or derate the engine 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

The first indication of a failing water temperature sensor is often an erratic or incorrect reading on the engine's temperature gauge. If the sensor completely fails, the gauge may show a constant cold or hot reading, or no reading at all, potentially leading to engine overheating without an alert. Prolonged operation with an inaccurate temperature reading risks severe engine damage due to overheating or improper fuel management.

Installation Tip

Ensure the engine coolant is cool before attempting removal to avoid burns and coolant spillage. Apply a small amount of thread sealant to the sensor threads, but avoid getting any sealant into the sensor tip itself.

Service Note

When replacing the water temperature sensor, it is advisable to check the condition of the coolant and the radiator cap.
