Installation Notes and Tips

Verify the connector style, thread size, and OE reference before installation. This Vemo V30-72-0125 sensor uses a 2-pin plug and M14 x 1.5 thread, and the fitment notes specify engine-block location with seal. For Mercedes-Benz C63 AMG, E63 AMG, and other AMG applications, confirm the original sensor configuration against the vehicle’s OE number 0051532328 before replacement.

Because coolant sensors are part of the engine management system, inspect the connector, wiring, and cooling system condition during service. This part cross-references Four Seasons 33035 and ACI 82201 for the same application.
