What direction does the coolant flow in a Mercedes 240d does it flow out of the engine head and in to the pump on the bottom left or vice versa?
(looking from the front side)
From the central belt-driven water pump (left side of engine) to AUX electrical pump to the monovalve (control valve for interior heat).
It then goes out of the monovalve by two hoses (left and right) into heater core, back into the engine block through a single hose on the right side.

Take it to dealer and hope they do it correctly, There is a plug on bottom of radiator loosen and it drains coolant out of radiator, but not out of engine, There are plugs on the side of the engine block that have to be removed to drain coolant out of block. Probably impossible to get to and accidents happen, sorry I hope this helps some.
The radiator fan is designed to run continuously while the engine is running so that the temperature of the coolant can be lowered. The coolant is continuously run through the engine, collecting engine heat and dispersing it over the radiator fins; while the fan blows the fins and cooling off the coolant before recirculating back through the engine in a continuous cycle.
Your 1989 Ford econoline has a coolant leak under the engine are there freeze plugs or something that would make it leak from there?
My car is leaking coolant from the top of my engine under the manifold and dripping down drivers side what could be wrong with my '99 Chevy Malibu leaking coolant?
The radiator was just replaced and now green coolant is coming out. No smoke no other symptoms - but coolant comes almost all out. What's wrong Looks like from the bottom of engine.?
coolant is not circulating - open the heater and bleed the system ++ Another Answer ++ If the lower radiator hose is installed correctly and the hose clamp is tight and the "coolant comes almost all out ... like from the bottom of the engine", you may have a bad freeze plug that either rusted or popped out. You might want to get under the vehicle and inspect the bottom part of the engine. CAUTION…
