Alot of times, the symptoms you describe could indicate that you have a lower intake gasket leak. Sometimes it is difficult to diagnose because the temp guage only reads the temp at a specific point and that does not reflect the temp at all points in the motor. I agree with the first suggestion that you shoud run your finger underneath the water pump pulley to see if the weep hole is leaking but it is more likely that you are sucking in air pockets through your intake gasket. Check the valley underneath your air inlet (on the top of the motor) for coolant. And also, green (glycol) based coolant has been known to damage aluminum radiators.

The rust is probably in the engine. There are many little pockets, water ways, water jackets (around the cylinders), etc, so getting all the rust out without dunking the block and heads in a cleaning tank is about imposible. I would recommend giving it really good flush every 4 to 6 months. I would try flushing the radiator before replacing it because it is probably not rusted, even though it is full of gunk.

Remove the plugs and see if any have water on them If so, you have a blown head gasket. Also check for coolant in the engine oil. Unless you disconnected something while you were working there is no reason for it not to start after doing what you did. Do you know where coolant was leaking out?
