Product Details

This febi coolant level sensor is used to monitor coolant reservoir level and provide the signal needed by the vehicle’s warning system. When the sensor or its circuit becomes unreliable, drivers may see low coolant warnings, intermittent alerts, or inaccurate level readings. Febi 26115 cross-references Land Rover PCJ000020 and PCJ500020 for the same application.

Common Symptoms It Addresses

• Low coolant warning light stays on without an actual coolant loss
• Coolant level warning appears intermittently
• Faulty or inconsistent reservoir level readings
• Electrical connection issues at the coolant level sensor
• Replacement needed during cooling system repair on BMW or Range Rover models

Installation Notes and Tips

Confirm connector style, lead length, and vehicle application before installation. Inspect the coolant reservoir, wiring, and terminals for damage or corrosion before fitting the new sensor. After installation, verify the cooling system is filled to the correct level and check for warning messages after the engine reaches operating temperature.
