I feel this might apply to me as well, after i had a hose replaced the temperature has been stuck higher than ever before, i live in texas so its very hot right now and the temperature not being where it was for the first 5 years normally is disturbing, I do not know what kind of coolant exactly they put in it last time but i do know they had to flush it. which would be better for me? cuz if this is just a simple coolant switch i will be happy.
