How do you bleed the cooling system after replacing the radiator and coolant on a Mercedes Benz 190e 2.6 89?

Locate the thermostat housing it sits between the fan and engine and has a small hose going to the reservoir of the radiator. To bleed the cooling system you need to remove this hose, start the car and keep filling the reservoir until water comes out of the top of the thermostat housing. With the water jetting out reconnect and tighten this hose. NOTE: Be careful if your housing cover is made of plastic as the small outlet can braek easily if too much pressure is applied while tightning the hose.
