The plug at the back of the expansion tank is leaking. I'm guessing the o-ring is bad. Anyone know if this part can be had and from where? My mechanic replaced the tank about 3 months ago when I had him do the oil/filter. The part does not look new, but is it generally come with the new tank?

TIA

I would suggest to get some Dow Corning 111 and put it on all of the O rings in the hoses of the coolant system,
this will keep them soft and thus they wont leak.
IIRC I had to swap the plug from my old tank to the new one
