4309449 Coolant Temperature Level Sensor — Cat C15 C18

This coolant temperature and level sensor is an essential electronic component that monitors the engine's coolant temperature and fluid level, transmitting this vital data to the engine control unit (ECU) or dashboard display. Manufactured to meet precise OEM specifications, it provides accurate readings crucial for preventing overheating, unlike a faulty sensor that may give erratic readings or fail to report critical changes. Operators may observe inaccurate temperature gauges, engine overheating warnings, or the engine shutting down unexpectedly 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 sign of a failing coolant temperature and level sensor might be an erratic or incorrect reading on the temperature gauge, or an engine warning light related to coolant status. If the sensor fails completely, the ECU may not receive critical temperature data, leading to potential engine overheating and subsequent shutdown. Continued operation without accurate temperature monitoring risks severe engine damage from excessive heat.

Installation Tip

Ensure the engine is completely cool before attempting to remove the old sensor to avoid burns. Clean the sensor port threads thoroughly to ensure a proper seal with the new sensor.

Service Note

Inspect the coolant level and condition, and check the radiator and hoses for any signs of leaks or damage when replacing the coolant temperature sensor.
