Its a Chevy 400 small block.I just put a new thermostat, upper and lower hoses, and a cap on her and she still heats up, however, when she is idle the temp tops out around 210 (probably 195 since the thermostat opens) then stays there which I expect. Then she is all warmed up for about 8 minutes now, so I put her in gear and take her down the road and not a 1/4 mile she is at 260+. I really cannot imagine that the head gaskets are blown if she is overheating that fast. The only other thing it could be is the Water Pump. It is not loose or show any leaks, but perhapes the insides are bad. Maybe it is not circulating the coolant, leading to a hight temp. Think this could be it? If the gasket was blown, it would still use up all the coolant before it would heat up right? I still have coolant when it overheats, but it does fart a little coolant onto the ground only when the temp hits 260+ from the overflow bottle. Let me know if you have heard of this problem ever happening. I just dont want to have to pull heads off and fine nothing wrong. But I will get her sniffed out if I can keep it cool enough to take it 1/4 mile down the road to the shop. Thanks a lot.
