When tested my concentration was over 80% That would explain the 110* 5 minute warm-ups..lol.

I did a flush last week and it made a huge difference, and it needed it. When I took the block plugs out, nothing came out! I looked and it appeared as though the holes were blank, I poked with a screwdriver and there was a layer of sludge. enough to stop the coolant from coming out...

I have a flushed system, a 60% water mixture, and running temps are 80-80*c
