I took my 49 to a show on Friday and on the way it got very hot (240 on the interstate), as you all know by now, it has a 350 crate engine. I this car is driven almost daily, and I have never had any issues before. My first thought was a stuck thermostat. I replaced it, and also checked for collapsed hoses, and re filled the coolant. It still got hot, the temp was at 210 when I opened the radiator cap to the first notch, nothing erupted out, and there seemed to be no pressure, i took it all the way off and the coolant level remained the same, even after the thermostat had opened, and did not appear to be circulating. The coolant in the radiator was pretty hot but you could stick your finger in it without burning it.This leads me to believe the propellar in the water pump is no longer turning. The belt is tight, and the fan runs as should, and the signs of a failing water pump are not present (loose fan blade, leaking), so is it possible that something failed on the inside causing it to not work without any external signs?
