new thermostat & water pump..still overheating, help!b

[millrat86]

If it does have a clutch type fan I must agree w/Jester make sure it functions properly ie., you should feel slight resistance when you try to turn it by hand. Is the thermostat installed correctly? Is all the air worked out of the system? Do you have the correct rotation water pump? Did you have this problem before the water pump/thermostat change? Does the the lower radiator hose flatten out as it gets hot? I had to fabricate a spring for one of my lower hoses but that car only ran hot at highway speeds it sucked the lower hose flat. That cars radiator had restricted passages due to stop leak being added to correct pin holes from corrosion of the core.
