Odd coolant / Exhaust manifold Question

[bkboatnsleds]

We put the Lq9 6.0 motor in my Tahoe..

All was smooth but ONE tiny issue.. I forgot to put one of the exhaust manifold bolts on he drivers side.. 2nd or 3rd one from front.

Reason I saw this was b/c when we started the truck we noticed some coolant seeping from that hole. AS soon as we put the bolt in, there was no more issue.

I find it weird that coolant would come OUT of that exhaust manifold hole...

Thoughts??

There shouldn't be coolant seeping from ANY of the holes where the exhaust manifolds bolt into. Possible that there may be a small crack in the area inside the hole.

Any ideas? Think its a problem to just put some thread sealant on the bolt?

makes no sense

I've never encountered that before, doesn't sound like a good thing!
