• Plug-and-play electrical connection for straightforward installation
• High-quality polymer and corrosion-resistant metal construction
• Alloy conductors help reduce electrical resistance for consistent signal output
• Designed for reliable operation in high-heat cooling system environments
• Guaranteed fitment for listed applications
• 24 Month Unlimited Mileage Warranty

Fitment and Application Details

Compatible With 2003-2006 Dodge Sprinter 2500 and 2003-2006 Dodge Sprinter 3500, as well as select Mercedes-Benz models including 1990-1996 S-Class, SL-Class, C-Class, and E-Class applications. This part number 1295450224 is also referenced as URO-008139 and 129 545 0224 for the same application.

Use this coolant level sensor when the reservoir-mounted sensor is no longer reporting coolant level correctly. On Mercedes-Benz S320, S420, S500, S600, SL320, SL500, SL600, C220, C280, C36 AMG, S350, 300SD, 300SE, 300SL, 400SEL, 500SEC, 500SEL, 500SL, 600SEC, 600SEL, 600SL, 400E, and 400SE applications, it supports accurate low-coolant warning function. Part number 1295450224 is built for direct OE-style replacement service.

What It Helps Resolve

• False low coolant indicator warnings
• No warning when coolant level drops too low
• Faulty reservoir sensor signal output
• Electrical resistance issues affecting sensor accuracy
• Heat- and corrosion-related sensor failure in the cooling system

Installation Notes

Install the sensor directly into the coolant reservoir tank and connect the wiring harness using the plug-and-play interface. Verify reservoir condition and connector integrity before installation, and confirm the cooling system is properly filled and bled after service.

Quality Assurance
