What is this plug under my water pump?

[OM3GA]

I think this thing might have been leaking... or maybe the water pump was leaking onto it giving an illusion that it was leaking. What is this?!?!?!

Im not a 100% sure, so dont' quote me, but i would be that would be a drain plug.

Im pretty sure it is a drain plug for coolant, but i thought it was leaking so we tried to take it out but it will not break free so im scared lol. I dont think it moved at all but now im paranoid that we even tried to loosen it i feel like it could cause problems

my car is down from leak from same spot. even with my new water pump and seal. I cant remove it either, well with all the dif type tool bits nothing fits right an dont want to strip it out. My car down for 2 week now anyone got advice?

Show us a pic of the mating surface of the water pump.

I don't think that plug is leaking. I think it was coming from the pump, as the mating surfaces in that area are really not very good (from what I can tell via pics).

I don't think that plug is leaking. I think it was coming from the pump

I seen that plug leak on mine with new sealent on water pump. do you know how to remove the plug?

[AZhitman]

Nope.

I'd clean it real good with a wirewheel on a drill and some brake cleaner and smear some JB Weld around it.

Seriously.

I did that on a freeze plug on my old Q45, since replacing it would have meant pulling the engine. Held up for 7 years.

I even ask nissan tech and he didnt know. I thought about doing gasket sealer over it but that not work long term. Did you use aluminum type jb stuff?

[OM3GA]

Im for sure not doing any type of JB weld at all, This engine is costing me $7000 and ill sell everything before i run JB weld on there lol, I want to do this right but i have no idea what to do to get that thing out or if that things even leaking. How can it leak it its so damn tight? Right?

I think its the spaces between threads I don't want to jb either.
