Throne parts at it? That is rather insulting. I replaced a 30+ year old radiator, thermostat, and hoses on a 32k mile car that spent most of it's life sitting. Seems to me I took the proper steps to work toward fixing this problem. Not much more I can do till the shroud gets hear. And I checked; not one of the local parts stores carry the hose with a spring. But as it is over heating at idle, it is pretty easy to see that that is not the problem. The more I look at how far the fan is from the radiator I am sure that the shroud will fix the problem.
