DIY radiator flush help needed
https://mbworld.org/forums/showthrea...radiator+flush
The above doesn't go into detail as to if the engine should be hot enough for the thermostate to open so that all the fluid come out, etc.
Can somebody explaine the different steps to do this?
Should I drain the fluid when the engine is hot or cold, the first time?
do I leave the engine on when the fluid is coming out, etc.
thanks
