Thank you very much for the info. I have the thermostat in correctly. The water was rusty looking, I used a radiator flush to flush it. When I get it back together I will flush it one more time for good measure. The blades on the water pump look in good shape, the bearing is going out, so I am replacing the water pump. I do not have a bypass line. I have several veins in the water pump housing. I am working on removing the housing, and I will make sure they are not restricted. I am now wondering if I had an air bubble in the water pump housing. I will make sure I do not when I re-assemble everything. I amaze myself sometimes, the steps I forget to take when I am a mechanic while I am working to get production out.
