1834760 Water Pressure Sensor — Cat C18 C32

This water pressure sensor measures the coolant pressure within the engine's cooling system, transmitting this data to the engine control unit for monitoring and management. It is constructed to meet exacting OEM standards, providing accurate readings that are essential for preventing overheating, unlike a worn sensor that might drift or fail. Operators might observe a coolant pressure warning light, erratic temperature gauge readings, or a loss of engine power if this sensor is not functioning correctly.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing water pressure sensor may initially cause the coolant pressure warning light to illuminate intermittently. If the issue progresses, the engine control module may receive incorrect pressure data, leading to overheating or reduced engine performance. Continued operation with a faulty sensor increases the risk of severe engine damage due to overheating.

Installation Tip

Ensure the engine coolant is cool before attempting removal to prevent burns and excessive fluid loss. Apply a small amount of thread sealant suitable for coolant systems to the threads of the new sensor before installation.

Service Note

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