Walker 211-2116 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

Walker Sender Only 211-2116 is an OE replacement engine coolant temperature sender for vehicles that rely on accurate coolant temperature data for engine management and dash gauge operation. It is built with a spade terminal design, one oblong connector, and two terminals for a factory-style electrical connection.

For BMW cooling system service, this sender helps restore proper temperature reporting on applications such as the BMW 318i, 325i, 525i, and M3. The Walker 211-2116 is made to match OE resistance values, thermal response, and thread type for direct replacement service.

Key Features

• Engine coolant temperature sender for ECU or instrument cluster input
• OE-style resistance values and thermal response curve
• Spade terminal design with one oblong connector
• Two-terminal electrical connection
• High-temperature, corrosion-resistant construction
• Direct-fit replacement for factory coolant port locations

Product Details

Walker Products Sender Only line focuses on direct replacement electrical senders that match original equipment specifications for fit and signal behavior. Part number 211-2116 threads into the original coolant sensor location, commonly in the engine block, thermostat housing, or intake manifold, and connects to the factory harness without modification. This part cross-references Dorman - HELP 82078 and Four Seasons 55474 for the same application.

On BMW applications, accurate coolant temperature input affects warm-up control, cooling fan operation, fuel delivery timing, and emissions readiness. The Walker 211-2116 supports reliable temperature reporting on BMW 318i, BMW 325is, and BMW M5 applications where the sender is specified in the cooling system circuit.

Common Problems This Sender Can Address

• Inaccurate dash temperature readings
• False or erratic gauge movement
• Fault codes related to coolant temperature signal loss
• Improper cooling fan or engine control behavior
• Hard starting or poor warm-up performance caused by incorrect temperature input

Installation Notes

Verify the connector style, terminal count, and thread type against the original sender before installation. Clean the mounting port and inspect the coolant passage for corrosion or debris before threading in the replacement. After installation, refill and bleed the cooling system as required by the vehicle service procedure.
