Good morning, I have a 2015 mercedes c 180 that is overheating I have already changed the electric water pump and the thermostatic valve but when I use the vehicle forcing the engine under load it overheats has anyone ever caught this situation

The electric pump is for the low temperature circuit, at first I don't think that circuit is your problem, I understand that there is no refrigerant consumption in the main circuit or overpressure, right?

when the engine overheats it leaks coolant through the reservoir and the hoses run out of pressure you have the cooling circuit diagram for this vehicle

[gcs190]

You should do a CO2 reagent test....

sorry i think the head gasket is blown, but do you have the cooling system diagram

That's why I told you to do the reagent test, you have all the information about the two circuits in WIS.

Though mine is B170 (w245), I had an overheating problem coming from clogged radiator.
