Dex Leaking

[[email protected]]

Johnathan,
Got an 03 lb7 recently and I've got dex leaking out of what appears to be the exhaust mainfold bolts (2 of them). I'm going to get it on a hoist tomorrow to look closer. Have you ever heard of this with the duramax. I can't believe that the bolts would actually enter the water jacket. Is this right?/

I cant say i have heard of the exhaust manifold bolts leaking coolant before . When you put it up on a hoist check around the head to make sure you did'nt push a head gasket .
