Not much, the excess coolant would be pushed out the overflow tube.
The process used for cooling water in a cooling tower is evaporation. Hot water is distributed over the fill material in the tower, allowing it to come into contact with air. As the water passes through the fill, some of it evaporates, taking away heat and cooling the remaining water before it is collected and circulated back into the system for cooling.
You may have air pockets trap in the cooling system.
It will spill?
Probably just over a gallon - buy the 50/50 premix and just fill it up
Fill the over flow tank to where it should be and just run the engine as usual. The system bleeds itself, Just check the over flow tank to make sure there is enough coolant in it.
Only when there is a failure in the cooling system.Only when there is a failure in the cooling system.
Many times after a Jeep cooling system is repaired, air bubbles trapped in the system will cause a overheat situation. If it is a 4.0l, with the engine cool remove the heater hose that is connected to the thermostat housing and fill the cooling system with the engine off. When coolant starts coming out of the engine side the system is almost as full as it gets.
They will fill up with silt and sediments.
To avoid over heatig
Possibly over heating and worst case scenario a blown engine.
Air in the system. Bleed the cooling system and remove any trapped air pockets.
Water in a cooling tower is cooled primarily through the process of evaporation. As warm water is distributed over fill material, a portion of it evaporates, which removes heat from the remaining water. This heat exchange lowers the temperature of the water that circulates back into the system. Additionally, the cooling effect is enhanced by the airflow through the tower, which facilitates the evaporation process.
