Default Fender bender, trying to identify coolant leaking problem. Help!

These blazers are like tanks.. the condenser and radiator are not damaged at all. Although the fan shifted and is bent slightly to the left .. The impact pushed everything into the motor as a whole. But nothing is touching it now.

Driving It home car was leaking and started to overheat.
I poured water
Car kept leaking and running hot
Tried pouring more water in but realized from first fill up the level didn't budge at all.
Towed it home.

I've been trying to mess around to see if I can find anything from radiator or hoses but I can't see anything from the top. I just jump started it to see if it would start leaking again... Nothing, although it did start to run hot and I cut it off.

Thanks
TOM

if the fan is bent the radiator made contact with it
take the upper fan shroud off and take a look

I have the upper shroud off. The radiator is in tact both sides have no damage to it whatsoever to be causing leaking from what I Can see.

I don't understand how coolant can leak out, then stop leaking and the coolant level stay the same meaning it's not using coolant.

IMO the only thing that could contact the fan to bend it is the radiator

are you sure you coolant level is still up ?

engine could be air locked - also make sure the fan clutch is ok and check the water pump for a bent shaft or the shaft being shoved into the pump and the impeller draging or a parted shaft inside the pump

Go with what odat suggested to check first. If no problems there then I would suggest pressure checking the radiator. My experience with these radiators is that the plastic end caps are "crimped: to the metal core of the radiator with an o-ring seal. When they start to leak it is difficult to see where the leak is coming from. Just drips out from under the truck. In your case the impact may have loosened this crimp seal through twisting of the supporting bracketry.
