Walker 1009-1013 Engine Coolant Level Sensor

Walker 1009-1013 Coolant Level Sensor

Walker 1009-1013 is an OE replacement engine coolant level sensor built to monitor coolant level in the reservoir or radiator and report low-fluid conditions to the ECU or driver. It uses an oblong female connector for a direct factory-style connection and is engineered for reliable signal behavior in demanding engine bay conditions.

Key Features

• OE replacement engine coolant level sensor for factory-style operation
• Oblong female connector for direct harness connection
• Monitors coolant level in the reservoir or radiator
• Built from heat-resistant materials for immersion in coolant
• Designed to match OE float response and electrical signal behavior
• Direct-fit design for original sensor port installation

Detailed Description

Walker 1009-1013 is designed for drivers and technicians replacing a failed coolant level sensor on vehicles such as Honda Civic and other applications that use this connector style. The sensor helps the vehicle detect low coolant conditions early, supporting ECU warning strategies and dashboard alerts before overheating occurs. This part cross-references N9267001 for the same application. Walker 1009-1013 is built to meet OE specifications for fluid resistance, electrical output, and float mechanism response, making it a practical choice for coolant system service on Honda Civic applications and similar factory-equipped vehicles.

What It Helps Solve

• Low coolant warning light that stays on or comes on intermittently
• Coolant level sensor fault codes stored in the ECU
• False low-coolant alerts caused by sensor wear or contamination
• Loss of coolant level monitoring in the reservoir or radiator
• Overheating risk from undetected coolant loss

Installation Notes and Tips

Verify connector shape and gender before ordering; this unit uses an oblong female connector. Confirm the original sensor port style and compare the removed part to Walker 1009-1013 before installation. Clean the mounting area and inspect the factory wiring harness for corrosion or damaged terminals so the replacement sensor can seat and connect properly.

Quality Assurance

Walker Products designs this coolant level sensor as an OE replacement component with materials selected for heat, vibration, and constant coolant exposure. The part is engineered to meet or exceed OE specifications for fit and signal behavior.
