Key Notes:

• Part Number: 377-6954
• Sensor Type: Water (coolant) temperature sensor
• Engine: Cat C3.3B, C3.8, C3.3, C2.4 diesel — fitted to applicable Cat D-series skid steer loaders, compact track loaders, multi terrain loaders, and mini excavators
• Application: Monitors engine coolant temperature and sends real-time data to the ECM, which uses this information to regulate fuel injection, fan speed, and cooling system operation — and to trigger high-temperature warnings and engine protection derates on applicable Cat equipment
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the engine temperature warning light is on, the machine is displaying a coolant temperature fault code, the temperature gauge reads incorrectly or not at all, or the machine is going into high-temperature derate mode without a genuine overheating condition — a failed coolant temperature sensor sends incorrect data to the ECM, causing improper cooling system response and false fault codes on applicable Cat Tier 4 equipment.
