Detailed Product Overview

Part number 1245400244 is built for Mercedes-Benz cooling systems that use an expansion-tank mounted coolant level sensor. It is a practical replacement when the original sensor triggers a false low coolant indicator or fails to alert the driver when coolant level drops too far. This sensor cross-references VEMO V30-72-0632 for the same application.

Compatible With Mercedes-Benz 190E, 260E, 300CE, 300D, 300E, 300SDL, 300SE, 300SEL, 300TE, 300TD, 350SD, 350SDL, 400E, 420SEL, 500E, 560SEC, 560SEL, and 560SL applications listed below. Part number 1245400244 is a direct OE-style solution for owners servicing older Mercedes-Benz cooling system warning circuits.

What It Helps Resolve

• False low coolant warning light on the instrument cluster
• Failure to warn the driver of low coolant level
• Intermittent coolant level sensor signal issues
• Electrical resistance problems caused by worn internal conductors
• Sensor degradation from heat and coolant exposure

Installation Notes

Install on the expansion tank where equipped. The plug-and-play connector is designed for direct replacement of the original sensor, making it suitable for routine cooling system service on Mercedes-Benz E-Class and S-Class-era vehicles. Verify the reservoir style and connector match the original part before installation.
