Description

Replace a broken, missing or fatigued manifold fastener with the Dorman exhaust bolt, part number 03423 from Dorman - HELP. Listed as an Exhaust Bolt / Exhaust Manifold Bolt Kit, it is designed to fit and work like the original part. It fits many vehicles, among them the 1988-1997 Toyota Corolla, 2000-2006 Toyota Camry and 2004-2013 Subaru Forester. See the Buyer's Guide tab for the full list and engine details.

An exhaust bolt helps hold the exhaust manifold in place so the manifold joint stays clamped and sealed. Dorman catalogs this part under both names: Exhaust Bolt and Exhaust Manifold Bolt Kit.

Direct replacement: built to drop in like the original on the listed applications.
Ideal solution: a practical choice when the original bolt has gone missing or broken from fatigue.
Durable construction: Dorman makes it from quality materials for dependable performance.
Trustworthy quality: backed by a U.S.-based team of product experts and more than a century of automotive experience.

Signs an exhaust bolt may need replacing: a ticking or puffing exhaust leak near the manifold, which may be more noticeable on a cold start; exhaust odor in the engine bay; or a bolt that is loose, broken or missing. If a failed bolt is the cause, this part replaces it. Inspect the manifold gasket and flange at the same time.
