Hello. Does anyone have any good suggestions for removing the bolts on the exhaust manifolds for this truck. It has an aluminum block. THanks.

Welcome aboard , Does this mean you have already tried and they will not turn? Heat would be my first suggestion . Running the engine till warm so the aluminum will expand . I have had bad luck with impact wrenches because the bolts tend to be soft after years of heating and cooling. spraying penetrating oil may cause a fire if hot . Rob
