I currently am not running a thermostat, i run my electrical fan at all times, brand new radiator, brand new water pump, new fan clutch, new head gasket. Anyone have a write up how to do the heater core? Might as well do it since its like the only thing left to do it seems like.

My overflow bottle hose came a little off it looked like it was on but would let the coolant leak out onto the ground. If your losing the coolant into the overflow and its not keeping enough it could be causing the over heat if it starts again I would look at that.

Let it idle with the rad cap off, keeping the rad full while idling. When air/coolant "burp" out of the rad, put a new rad cap on. For next several days, check coolant level in both the radiator and bottle, motor COLD.
