Dorman 674-187 Exhaust Manifold

Detailed Description

This exhaust manifold is engineered as an OE-style replacement for vehicles that need a precise manifold fit and proper exhaust sealing. The Dorman 674-187 uses a regular-grade cast iron design and is supplied with the gasket, flange, bolts, nuts, and lock washers required for the manifold and downpipe connection. If you are replacing a cracked manifold, repairing an exhaust leak, or restoring proper exhaust flow on a Dorman 674-187 application, this part is built for that service. It is a practical choice for exhaust manifold replacement on specified make/model applications where the original manifold has failed.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

  • Broken or corroded manifold-to-downpipe connection
  • Noise from escaping exhaust gases near the engine
  • Failed gasket sealing at the exhaust manifold

Installation Notes and Tips

Verify the port shape, mounting points, and exhaust connection before installation. Clean the mating surfaces thoroughly and inspect the cylinder head and downpipe flange for damage before fitting the new manifold. Confirm vehicle application details for your make/model before ordering, especially when sourcing a Dorman 674-187 exhaust manifold replacement.

Quality Assurance

This manifold is precision-engineered and manufactured to match original fit and function on specified vehicles. Dorman 674-187 is built as a direct replacement exhaust manifold for repair work where OE-style dimensions and included sealing components matter.
