Good Day. Can anyone help me identify this leak?
::::Background::::
-1998 Mitsubishi Eclipse GS 86,000 Miles, Non-Turbo original engine.
-Drove it 2 Miles before I bought it. It had a leaky rear main seal.
-I had the rear main seal replaced and a new clutch put in.
-I drove 30 slow miles (less than 5,000 rpm). I found coolant was pouring out of the vehicle.
::::Leak::::
-Inspected the following and found no leaks:
---upper radiator hose
---lower radiator hose
---radiator drain plug
---bottom of radiator
-With the car off, Coolant (Radiator fluid, Water) pours out from this location next to the core plug (Welsh plugs, frost plugs or freeze plugs). The brass (colored?) bolt that is wrapped in plumbers tape and has a hole in the middle is the item I'd like to be identified. It is located on the passenger side of the vehicle, behind the engine, behind the oil filter. I tried to tighten the bolt but this does not stop the coolant flow.
-I noticed on this picture of the 420a engine has this hole plugged.
Maybe some one put in an aftermarket engine block coolant drain plug?
Can some one please identify this part.
Thank you
Got it out. Top most bolt takes 3/8ths (I used 10mm). Bottom most bolt takes 9/16ths (I used 15mm).
It looks like this was some ones quick job. The threads fit perfectly into the engine block. Inside the three bolts there was this small brass fitting and a rubber fitting.
All of the brass fittings that my local Autozone carried had incorrect thread pitch to fit into the engine block, however they did carry the middle of the three brass fittings with a plug. This made me go to Lowe's to see if I could get the larger size brass fitting as a plug. I found that a 1/4" plug fit perfectly.
Here is a comparison of what came out of my engine block and what went in.
After putting on some Teflon tape like the original installation had and installing the new brass fitting, my eclipse is once again leak free. I hope these photos can help others.

P.S. Does any one know the technical name for this hole or why it was created? I'm guessing to find coolant temperature for inboard gauge pods (the previous owner installed some, but not for coolant temp).
