You may have to pull the thermostat to look at it. put it in a pan of boiling water and see if it opens correctly. I have seen more than a couple of thermostats stick open btw.

That doesn't explain the low flow AND the cool temps though??? The only thing that comes to mind is when I have seen bad water pumps with nearly completely eroded impellers due to cavitation from running straight H20 with lots of rusty water.
