Engine Coolant Temperature Sender for Mercedes-Benz
Walker Sender Only 211-1089 is an OE replacement engine coolant temperature sender that reports coolant temperature to the ECU or instrument cluster. For 1995 Mercedes-Benz C220, E320, and E420 applications, it helps maintain accurate temperature feedback for engine management and dash gauge operation.
Key Features
- OE replacement coolant temperature sender for factory-style temperature reporting
- Measures engine coolant temperature and sends the signal to the ECU or instrument cluster
- Built to OE resistance values, thermal response curves, and mounting thread type
- High-temperature, corrosion-resistant construction for pressurized coolant environments
- Single connector design with circle connector shape and butt terminal type
- Direct-fit design for original sender locations such as the engine block, thermostat housing, or intake manifold
Product Details
Walker Products Sender Only line focuses on direct OE-style replacement sensors for cooling system and engine management service. Part number 211-1089 is engineered for accurate coolant temperature signaling, which supports warm-up control, cooling fan activation, fuel injection timing, and emissions system readiness. This part cross-references Hella 009107251 for the same application.
Compatible With 1995 Mercedes-Benz C220, sender only; 1995 Mercedes-Benz E320, sender only; and 1995 Mercedes-Benz E420, sender only. If your Mercedes-Benz C220, E320, or E420 shows incorrect temperature data or inconsistent gauge behavior, 211-1089 restores the factory-style sender interface.
Common Issues This Part Can Address
- Inaccurate coolant temperature readings
- False or erratic dash gauge behavior
- Improper cooling fan operation
- Incorrect fuel injection timing caused by bad temperature input
- Emissions readiness problems related to faulty temperature data
Installation Notes
Install the sender in the original threaded port and connect it to the factory wiring harness. Verify the connector style, thread type, and sensor location before installation, especially on 1995 Mercedes-Benz C220, E320, and E420 models. Clean the mounting area and inspect the cooling system for leaks or contamination that could affect sensor performance.
Quality Assurance
Walker coolant temperature senders are manufactured to OE specifications for fit, resistance values, and thermal response, with materials selected for heat, vibration, and coolant exposure resistance.
