ok, so i have a 95 del sol S with a d16z6 motor swap, just swapped in the motor and hooked everything up, everything was running smooth till i started to fill the coolant... i bought a 50/50 premixed coolant from advance auto parts, and i couldnt find my coolant drain plug at the bottom of the radiator so i went to honda and bought a new one, so i put it in, and when i started to fill it up, coolant started leaking from the little hole below the plug itself, and i dont know what could be causing this... any ideas?

 

Take a pic of exactly where it's leaking from.

Or

Where is it leaking from:

 

here it is...

 

jb weld it
if its a hole

 

but its like molded with the plastic like its supposed to be there

 

Do you see the path that it's taking to get to that center point?

Does it run out of the drain plug and runs back where it leaks from that point or does it leak from the drain hole?

It seems there is an o-ring that goes inside the area of the drain ****. Do you have one in there or did you replace it with a new one?

ok i got it they didnt give me an o-ring with the plug

 

Maybe the old one is shot. Replace it with a new one and see if the problem is solved.
