Hi guys,
The water is rising in the reserve tank.  I usually think that it is from the gas coming from the engine that pressing out the water and then leaves the pressure tank half empty.  This time the pressure tank is not missing water.  The car is overheating too.  Somehow the coolant looks really clean.  Unusually clean, after I filled it up when the green coolant was let out first.  My experience is that the coolant is not clean in a case like this.  The hoses are hot on both sides of the thermostat and at the radiator.  Not that explains the whole story...
Well, my question is; any of you know what trouble I am having?
