The second one was terribly tight and i twisted it off. Ok now the thermo should come off right--wrong again-- with nothing holding it but the gasket I beat and beat with a hammer and it would'nt lift off. aS FAR AS i CAN SEE THERE IS NOTHING HOLDING IT. Put the one nut back on and it doesnt leak, but I want to fix it right before winter. 2 questions: what do I use to get the sheared bolt out and why wont the cover come off. are these studs that are mounted from the factory- how do i replace these- thanks for your help in advance [Reply]  [No Email]

The reason it breaks is usually because the bolt is corroded to the water neck as much as the manifold. If that's what happened then some WD-40 or a penetrant in the hole and work it gently. When it starts moving don't force it, it'll loosen up with more movement. When you reassemble coat the whole shank of the bolt with neversieze.   [Reply]  [No Email]
