I over heated the engine and I found collent in my throttle body and the intake manifold. I'm trying to figure out wear the leak could be coming from? I know its not the head gasket becuase I don't have milky oil.

I don't know too much mechanically about where that would be leaking from but I do know over heating the engine on a Legend was a big problem with that block. My dad had one and it happened quite often.

Is the throttle body coolant line leaking?

Yep, later versions of that engine had more aggressive fans/timing which prevented headgasket issues.

if you have coolant INSIDE your TB and IM, you could have a cracked TB... there is a coolant line which goes into the TB to help warm up the TB during cold startup to prevent the butterfly from sticking... if the TB is cracked from the inside, the coolant will leak into the TB and the incoming air will draw the coolant into the IM...

one way to check for this would be to just bypass the coolant line to the TB... you don't really need it... i have it bypassed on my car... and if you see no more coolant in your TB/IM, then problem solved... why did the car overheat in the first place?

Change your thermostat. Remove the top radiator hose from the engine side, coolant will spill, and the thermostat is right there. $12 at a local auto store. Get a new gasket and o-ring too. It should take 10 min tops and will fix your heating problem (most likely). Buy a new radiator cap while your at it too. $7 is much cheaper than repairs.
