I am coming back to this thread for some related question.

The passenger side for my lhd car is barely blowing any heated air at all now in the winter time so I guess my matrix is blocked, I want to flush it but I also want to avoid the hassle of taking it out of it's place, would rather do a flush from the engine bay side. Now to get to my questions:

Would I have to cut hoses and join them back afterwards with some simple hose connectors and clamps? Or can they simply be undone somewhere on their length after the firewall?

Also, when flushing, is it important to do it only one way or can I flush it both ways?

Which hose is the one running at the top of the matrix? I am thinking of pushing out all of the coolant from the matrix with the help of a small air compressor and then filling it with some descaler through the hose that goes to the top of the matrix if water can flow through it in that direction too, what do you guys think?
