Hi,

I flushed the system last night using a liquid detergent to eliminate the oil contamination. I turned the heater on (and that electic pump has operating!). Nothing happend and oil remained on the hoses.

After that, I made another flush using a can of a comercial "radiator cleaner". Some oil came out of the system but I still see a lot of contamination. Upper and lower hoses have lots of oil. They look like if I had apply butter inside the hoses. This is crazy. I don't know how to remove this thing from the system. I guess this will take a lot of time and some aditional flushes but flushing the system takes a lot of time.

Thanks
