There is a coolant tube going into the bottom right of the engine. There is an entry tube and an exit tube. The one tube came loose and leaked coolant everywhere. I re-attached it with no problem. The leak has disappeared but now it seems coolant is no longer entering the engine and it is over heating. Is there some form a reset needed or could there be a water pump failure. Any help is appreciated. Thanks.

That is a heater hose, they fail often due to oil soaking.

Replace the whole hose.

You need to then fill the cooling system up to the top and bleed it properly. Fill the system totally then use your hand to cover the hole and pump the rad hoses with your other hand. This will get much of the air out. Then cap the system, start the engine and open the bleed screw on the rad. Warm up the engine and then close the bleed screw as coolant begins to flow out.

Thank you for the quick and detailed response. Problem solved.
