Question about Cars & Trucks
You take the thermostat out before using sealer because the sealer will setup in the thermostat.

If you used some rad sealer the thermostat is probably bad, so it will be overheating, this will blow the head gasket. take the thermostat out and refit. without the it in, go for a drive, the temp should rise up and down. when you come back leave to cool down. and flush the system out with fresh water, and then replace with new thermostat, if no leaks top up with antifreeze and water, leave top off and run engine to get bubbles out of engine squeeze radiator pipes as warming up. and top up water as it goes below line. when all air is out and fan has come on to say its at full temp. leave to go cold. and top up if needed and put cap back on.

Hey there Dave,
Had the same thing happen to my Wrangler about three years ago.
It was the weep hole too.
I drained the coolant, dried the weep hole and plugged it with a small amount of that solid epoxy they market to fix holes in gas tanks. I refilled the radiator and the plug held.
It's still holding.
Just an alternative option

try to run the water pump without hoses, and add water in the 'in' side, if is powers out the other side, then it's fine. how is your water/coolant mix?

You probably never cleaned the cooling system out.
If you have not get it done by pros.
It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.
Check and see also if the heater valve is working.
As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.

when installing new o-ring on tube, lubricate o-ring and stick it in water pump. Then pull pressure back on tube and then tighten hold down clamp. problem solved
