Please illustrate me as I am not very familiar with the cooling system.

Best regards

I have changed lots of radiators over the years but never have worked on Mercedes. My 95 E320 has the same symptoms as you described. How to I get the coolant to flow into the system from the fill tank after changing the thermostsat and now flushing and filling. You can't be too basic. Thanks. Dave

Remove the thermostat housing and the thermostat so that you can fill the engine block with coolant/water mix. Reinstall the thermostat and the thermostat housing then fill the radiator with coolant/water mix and add coolant/water mix to the expansion tank. Run the engine up to operating temperature and add more coolant/water mix to the expansion tank as required.
