coolant leak, not overflow (searched)
 
ok so i been leaking coolant for the last few days, at first my friend (has an fd) says its probably a bubble and just kinda bleed it and it should be fine. so i filled it all up and thought i got all the bubbles out.. anyhow..

its not leaking from the over flow tank or the ast. it seems like its comming from the radiator but i cant quite tell. it only seems to leak only after a few mins with the car off. i dont know a great deal about removing shit from the engine bay but i moved what i could to try to investigate the source..

in this pic (not very good sorry) the green line shows where coolant beads down the entire length of the top of the radiator. and seems to be dripping down both sides of the radiator then onto the ground. a much bigger pool always accumulates at the passenger side. i checked the top radiator hose to see where it connects into the radiator if it is wet and it feels dry. i assume its a bad radiator but i just wanted some pro opinions before i shell out 300 for a koyo. thanks in advance i love this forum!

Maybe the hose that connects from the overflow tank to the radiator? The big thick one? I had a leak their once...

Sounds like the seal of the upper plastic end tank to the radiator is failing. When you shut off the engine, heat builds up and increases the pressure in the cooling system, making it leak. This is a fairly common problem.

You need to get a new radiator.

My thoughts exactly. It is another issue with the stock radiator that isnt talked about much but it is very common.

If you haven't purchased it, I would recommend the Fluidyne instead.
