The Ford Barn - View Single Post - UPDATE....Ok so a brand new radiator and it still runs hot

I have found that the outside temps directly impact how the cooling system performs. Drove 30 miles Saturday 40-45 mph outside temps was around 68 degrees. Car ran 160-170 degrees. On the return drive temps were around 88 degress and car ran 190-200 degrees.
Until I can afford a new radiator I guess I will pull the head and check the gasket and check the water pump impeller and make sure it isn't spinning on the shaft.
I also noticed that at the top of the radiator tank the temps are what the gauge shows. At the bottom of the tank the temps were around 150. At the inlet neck they were close to what the gauge shows. Almost like it's not pulling the cool water up but I can see the water moving thru the radiator. Increase speed and it the flow increases. ARRRGGGGG!
