Coolant from exhaust manifold studs??

Is it normal to have coolant come out of the exhaust manifold studs?  My first Mopar, so I am a noob.  I had a stud that decided to come out instead of the nut.  But, I need to remove all of them to install headers.  I will have to drain the coolant, I guess.  Seems like an odd way to engineer the heads, what it is the point?  It will be a PITA, since I just put the manifolds back on for cam break-in, then added new coolant.

yup, crappy design but it worked.  I have had numerous studs do that especially with our small block chally vert.  What is more of a pain in the ass is when the holes strip and you have to try and put an oversized stud in its place and get it to seal.

Ok, thanks for the reply.  :2thumbs:   It was a bit of a surprise, since I was standing under the lift when it happened.  I managed to miss taking a shower in anti-freeze.  :laugh:

You get used to the green, sweet smelling shower.   :lol:

I have one bolt on my passenger side headers that has an occasional coolant drip from it.  The bolt was taken out and put back in with locktite to get to this point, the leak was worse before that.  My mechanic says that in time it should stop on it's own.  When a drop falls on my headers it smells like maple syrup.

BB Chryslers are set up this way...Simple fix...I leave the studs in the heads and install the headers on the factory studs....Time to remove Headers? PITA, but I don't have the issues with headers BOLTS like they tend to have...

Yeah, it definitely has a unique smell to it.

I was debating on just leaving the studs too.  It is much easier to put the gaskets and headers on the studs vs. trying to hold them in place and get a bolt started.  I just wanted to use the nice shiny new bolts that came with the headers, instead of the old manifold nuts.  I can pickup some new ones to solve that.  I probably will, since the discovery of coolant there.  Thanks!
