I just have a question. It has a 3.4 and I replaced the head gaskets and intake gasket awhile back and I broke one the front manifold studs when I was putting it back together and I just let it be. There is no exhaust leak. My question is would this in any way cause the heat gauge to still want to rise when you are on the freeway or in a drive thru? When you have to pass or go a little hard on the interstate like up hills it wants to rise and it is ok with normal driving on the freeway.
