Walker Products Engine Coolant Level Sensors are OE Replacement components designed to monitor the level of coolant in the reservoir or radiator and alert the ECU or driver when fluid drops below safe operating levels. This critical sensor prevents overheating by activating dashboard warning lights or triggering ECU-based engine protection strategies. Each Walker sensor is engineered to meet or exceed OE specifications for float mechanism response, electrical signal behavior, and fluid resistance. Built from durable, heat-resistant materials, these sensors are designed to withstand constant immersion in coolant as well as the high-temperature, high-vibration conditions found in modern engine bays. Designed for an exact OE fit, they connect seamlessly to the factory wiring harness and mount directly in the original sensor port—eliminating the need for any modifications. Whether used for routine replacement or to resolve an intermittent warning light or coolant-related fault code, Walker Coolant Level Sensors help ensure safe engine operation, avoid overheating, and maintain optimal system performance.
Characteristics include:
Built for Harsh Conditions: Constructed from high-temperature, fluid-resistant materials to ensure long-term performance under hood and under pressure.
Monitors Coolant Levels Accurately: Alerts the ECU or driver when coolant drops below safe operating thresholds to prevent overheating.
OE Replacement Design: Matches original sensor specs for float action, electrical response, and fluid compatibility.
Exact OE Fit: Installs directly into the factory reservoir or radiator with 100% fit and electrical connector alignment.
Supports Engine Protection Systems: Enables warning systems and ECU safeguards that prevent engine damage due to coolant loss.

Service was great, appreciated the phone call to confirm the vehicle. Parts arrived quick. OEM fit. Will be ordering brakes as you can see by the picture. Very impressed.
I have bought this rotor on part pioneer for my Q3 and installed and used for over a week, they are amazing no squeaks no noises brakes have improved 110%. This rotors are the best so far I’ve always bought rotors and used in all three of my cars and so far these ones are the best that I have ever bought.
