    The heater uses both those pipes, you have an air lock and need to purge it ( if you are sure the valve is open ok)
    do you mean these two smaler pipes on the pic? But at first glance they are mounted beneath at the engine - so how will flow the water in the one and back by the other?

    By the way: I saw, that the cooling fluid has green colour. Does anybody know if this is right for the motor?

      When you re-attach the pipes to the coolant system, the water pump wont purge the heater matrix on its own sometimes ..try leaving the cap off the radiator for 20 minutes .. then refilling .. and the same again until it needs no more, green is volvo standard coolant

        150psi would leave not much to blow with .

        I'll wait for the spring to arrive and then attack the blower with Hoover or similar brand

          well as I said to Muz above Mattir ...... one would need to use some common sense doing it ..... but'd beat any hoover hands down

          You wouldn't hoover out the radiator for the engine would you ...... just blast it out clean with the jet wash, is what most folk do ....... or carefully blow it out with the air line .... same sort of rad
          If it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

            Because I think the cooling liquid was old, I bleed the Motor ans filled new one in. For the two pipes of the heating I used a pump to refill them. I let the Motor run about 15 minutes an looked, if the cooler must be refilled, but the two pipes got warm only very slow. And one pipe was about 50°C and the other only about 20°C. The air from the heating was about 16°C (the outdoor temp was 10°C). So the heating works only minimal. The question is - why? The mysterious Thing are the two heating hoses which are located beneath. If there is no narrow between the pipes, they have the same physical pressure and so there no water will flow through the pipes.

            Can anynody tell how the correct working heating at the EC15B works (How many degrees at the heating airflow after so much minites)?

              It should be hot .. either you have not expelled all the air, or there is a restriction or kink in a hose somewhere or your valve is not working correctly

                I refilled the heating circuit again with cooling liquid and itīs not super but better. I took a pump and made tests, if the resistance with the down regulated heating lever is another as with the opened lever. It seems the same. But I think I will leave it so.

                An additional question: Is it normal, that the cooling fan of the engine is turning immediately after Startup? Is there no element which turns the fan on, when the water is hot? I think on a visco clutch.

                  As far as I have seen, the motor fan is always blowing, no matter what the temp is.

                      Yes its a direct drive ... anything else would be far too complicated for this machine

                        Yes - I made a second refill of this heating pipes and now itīs working acceptable. Maybe when all problems of my EC15 are solved I will make a rework. But for now itīs finished.
