⚡ At a Glance
- • Sensing Accuracy: Two-pin sensing changes electrical output with coolant level for clear low-level detection
- • Best for: Mercedes owners and independent garages seeking direct-fit replacement sensors
- • Not ideal for: Non-Mercedes vehicles or systems requiring multi-pin diagnostic interfaces
Two-pin coolant-level sensing transmits status to the engine control module via the engine harness. OE reference numbers align with a broad list of Mercedes-Benz models for straightforward replacements.
Accurate Low-Coolant Alerts – With two-pin level sensing and ECM feedback
Two-pin electrical sensing varies voltage or resistance with coolant level and routes the signal through the engine harness to the engine control module for monitoring. The ECM interprets the signal to trigger dash warnings or log diagnostic codes.
Reliable detection reduces the risk of unnoticed coolant loss and overheating. Clear electrical signalling helps workshops diagnose level faults quickly.
Broad Mercedes Fitment – Thanks to matching OE reference numbers
Reference OE part numbers include 2205450024, 2038700951, 2E0919372 and 68013657AA, and compatibility covers numerous Mercedes-Benz passenger cars and vans listed in the description. Fitment spans multiple model lines and year ranges as specified.
Easier part selection for many Mercedes applications, lowering the chance of ordering the wrong item. Compatibility with common model families speeds repairs for owners and garages.
Engine-Bay Durability – With ABS construction to OEM specifications
Manufactured from ABS material and produced in accordance with OEM specifications to resist heat and coolant exposure common in radiator expansion tank locations. Design follows original equipment form and connector style.
Tough construction helps the sensor withstand under-bonnet conditions and prolonged exposure to coolant. OEM-style build reduces the need for frequent replacements.
