I have flush the whole system out two times, the only thing that is different is electric fans, did have a flex fan. have a bottle of water wetter i the system and it made about 5 degrees different. was told to day to open the headers up a run it to see if it changes any thing. the mufflers are about 15 years old. had 50/50 mix in there and it run hotter. will try the open headers in a few days and see what happens. thanks for helping.
