Walker 211-2187 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

Walker 211-2187 is an OE replacement engine coolant temperature sender built to report coolant temperature to the ECU or instrument cluster. For vehicles that rely on accurate temperature input for warm-up control, cooling fan operation, fuel delivery, and emissions readiness, this brass sender restores the signal the system expects.

Walker Sender Only components are built for direct replacement service, with OE-style resistance values, thermal response, and thread design. This part cross-references FEL-PRO 35215 for the same application.

Key Features

• Brass sender body for high-temperature coolant service
• Blade terminal design with 3 terminals and 2 connectors
• Male connector / female terminal configuration
• Flat washer seal included for the mounting point
• Mounting hardware included for service replacement
• OE-style thread fit for factory coolant sender ports
• Built for use in engine block, thermostat housing, or intake manifold locations

Detailed Product Description

Walker 211-2187 is an engine coolant temperature sender for vehicles that depend on a precise coolant temperature signal for engine management and dash gauge operation. The brass construction resists corrosion in pressurized cooling systems, while the OE replacement design helps maintain the correct resistance curve and thermal response needed by the vehicle electronics. If you are servicing a cooling system concern on a Honda Civic, this sender provides the direct-fit replacement path for restoring accurate temperature reporting. It also serves as a practical replacement choice for other applications that use the same sender specification, including select vehicle platforms that cross-reference this part number.

The Sender Only line focuses on direct OE-style replacement parts for temperature monitoring and related engine control functions. Walker 211-2187 follows that approach with factory-style thread engagement and a connector layout that matches the original sensor interface.

Common Issues This Part Can Address

• Inaccurate dash temperature readings
• False high or low gauge behavior
• Cooling fan activation problems caused by bad temperature input
• Rough warm-up control from incorrect coolant temperature data
• Emissions readiness issues tied to faulty sensor feedback

Installation Notes and Tips

Install the sender in the original coolant temperature port and verify the thread type, connector shape, and terminal layout before installation. Drain coolant as needed to prevent spills, and inspect the sealing surface and wiring connector for corrosion or damage. After installation, refill and bleed the cooling system according to the vehicle service procedure, then confirm stable gauge operation and proper ECU temperature input.

Quality Assurance

Walker manufactures this sender to OE specifications for resistance values, thermal response, and mounting thread type. The brass construction and corrosion-resistant design are intended for long-term exposure to coolant, vibration, and thermal cycling.
