Exhaust manifold studs and nuts clamp the manifold to the cylinder head and hold the gasket under load. Repeated heat cycling can leave this hardware rusted, stretched or broken. Signs it may need replacing include a ticking exhaust leak near the manifold, exhaust odor under the hood, or a stud that snaps or strips during service. This Dorman exhaust manifold stud and nut uses an M8-1.25 thread. Consult the vehicle service information for installation torque and gasket requirements.
