Doctor Gollum , sorry, my English is not so good so when i said crystal clear , I ment only clear regular blue coloured but not so blurry with a bit of transparency in it ( i hope i wrote that right )
Polirara , what is the part number of the heater matrix, its not a bad idea just to change it , i think I can do it myself and save myself from trouble again, but since its an older model , is it easy to find? And how big it is in volume , I have a good friend in UK , i can ask him to get it for me
Biggriffin , yes i plan to change the coolant, before that i plan to do a flush of the system. I did that on my old opel rekord B ( which is very very similar to the omega ) .i bought some cleaning liquid , after releasing the coolant , flled the sysytem with water , put the liquid in, ran the car for 20 min .
And yes , my steering wheel is on the left side of the car ,
I just cleaned the matrix again, dirt came out again , but not so much .Not so black, more like yellow water mixed with oil
Heater is ok for now
