if the leak was near the lower radiator hose then most likly the water pump is bad. The thermosat is located on the upper radiator hose, and as long as it was installed the correct way there should be no issue there.
Please check belows if it is petrol vehicle,
1 Air filter & intake line.
2 Conditions of spark plugs
For heating problem,
1 radiator cap
2 cooling fan working or not
3 Radiator block
4 water pump for leaks
5 All radiator lines for leak
6 Thermostat valve
Probably not water pump. Engine is notourious for vapour lock.
Cooling system must be blead of air before thermostat will work. Cool bottom rad hose is a dead give away. If you are still watching this forum reply , and I will walk you through the only way I know how to make it work properly. It's actually easy if you do it my way. I have worked on lots of cars , and this engine was the hardest to bleed out. Did one Yesterday , and works perfect.
Did you burp the coolant? If not, you have air bubbles in the system that are trapped behind the thermostat, keeping it from opening. Run the car at idle until it's 3/4 of the way to overheating, then shut it down and let it cool. Pop the radiator cap and the air bubbles will burp out. Check the level of coolant in the radiator and expansion tank, top off as needed, and repeat a couple times, and you should be good to go.
If the cooling fans, water pump, radiator, and thermostat are all working properly and the engine is still overheating, I would take a look at something a little more simple, like a defective radiator cap. Try this inexpensive fix and see if it works. Sure hope this helps and good luck.
If it overheats very quickly, it likely has a bad thermostat. If the radiator does not fill easily when re-filling, likely the radiator is internally blocked and requires either a flush, boil out or replacement. Make sure any electric fans are properly operating. If you have any white smoke or coolant in engine oil, you may have a blown head gasket. A shop can identify this condition by checking for hydrocarbons in the cooling system, or by doing a compression or leakdown test.Do the easy stuff first...change the thermostat. If problem continues, go further with your diagnostics.
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.
