Walker 211-1040 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker Products 211-1040 is an engine coolant temperature sensor built for accurate coolant temperature reporting to the engine management system. It is a direct-fit replacement for select Saturn applications, including Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 models across the 1995-2002 range.

Walker Products has supplied fuel system and engine management components since 1946, with manufacturing and engineering processes focused on OE-level specifications. The 211-1040 is part of that sensor lineup and is intended for drivers and technicians replacing a failed coolant temperature sensor on Saturn SC1, Saturn SL2, or other listed Saturn models.

Key Features

• Engine coolant temperature sensor for engine management and temperature feedback
• Direct replacement for select 1995-2002 Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 applications
• Walker Products part number 211-1040 for catalog and service reference
• Built by an ISO 9001/IATF16949 certified manufacturer
• Manufactured to meet or exceed OEM standards and specifications

Product Details

This coolant temperature sensor monitors engine coolant temperature and sends that information to the vehicle control system so fuel delivery, idle strategy, and related engine functions can respond correctly. For Saturn SC1, Saturn SL1, and other covered models, a properly functioning sensor is important for stable drivability and accurate temperature-based engine control. Walker Products 211-1040 is engineered as an OE-style replacement for the listed Saturn fitments and is backed by Walker’s in-house manufacturing and technical support resources.

This part cross-references Standard Ignition TX73 for the same application.

Common Issues This Part May Resolve

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting when the engine is cold
• Rough idle or unstable warm-up behavior
• Rich or lean fuel control caused by faulty temperature input
• Check engine light related to coolant temperature sensor performance

Installation Notes and Tips

Verify the connector style and thread engagement before installation on your Saturn SC2, Saturn SW2, or other listed application. Inspect the cooling system for leaks, corrosion, or damaged wiring before replacing the sensor. Clear diagnostic trouble codes after installation and confirm the engine reaches normal operating temperature with a scan tool or gauge.

Quality Assurance

Walker Products manufactures engine sensors to meet or exceed OEM standards and specifications. The company’s ISO 9001/IATF16949 certification supports consistent production control, product management, and technical documentation for service use.
