Keep the exhaust manifold clamped tight and leak-free with the Dorman - HELP Exhaust Manifold Stud and Nut (MPN 03422CD). This fastener hardware threads into the cylinder head and secures the exhaust manifold, holding the joint together so exhaust gases stay routed through the system. It installs as a direct-fit replacement across a wide range of GM cars and crossovers, including the 2000 Saturn LS, 2002-2005 Chevrolet Cavalier, 2005-2010 Chevrolet Cobalt, 2004-2014 Chevrolet Malibu, 2008-2017 Chevrolet Equinox, 2010-2016 Buick LaCrosse and 2010-2017 GMC Terrain — see the Buyer's Guide tab for the full 34-application list.
- Purpose-built replacement: swaps out original studs and nuts that corrode, seize, or break at the exhaust manifold.
- Secure clamp load: reestablishes a tight connection between the exhaust manifold and cylinder head.
- Fresh hardware: replaces fasteners that are often damaged or unusable during manifold removal.
If a broken or corroded stud is the cause of a ticking exhaust leak, this hardware replaces it. Diagnose the source of the leak before ordering, and consult the vehicle service information for the correct torque procedure.
