  • Includes 2 bolts, 5 studs, and 5 nuts for complete manifold fastening

Durable Metal Construction and Precise Specifications

The Dorman 03400 kit features metal studs and nuts coated in zinc yellow to resist rust and corrosion commonly found in exhaust system environments. The studs measure 40 mm in length with an M10-1.25 thread size, matching OEM specifications for a secure fit on compatible Geo and Toyota exhaust manifolds. Bolts included are grade 5, providing the necessary strength to maintain manifold integrity under thermal expansion and vibration. This kit contains all necessary hardware to replace worn or damaged manifold fasteners, helping maintain exhaust system performance and preventing leaks.

Compatible Vehicles and Common Applications

This exhaust manifold hardware kit is compatible with the following vehicles:

  • Geo Celica
  • Toyota Corolla
  • Toyota Prizm

It is designed to address issues such as:

  • Loose or broken exhaust manifold studs and bolts
  • Exhaust leaks caused by damaged fasteners
  • Corrosion and rust on manifold hardware
  • Difficulty securing the exhaust manifold properly
  • Replacement of worn or missing nuts and bolts

Installation Notes and Tips

When installing the Dorman 03400 Exhaust Manifold Hardware Kit, ensure all old hardware is fully removed and the manifold surface is clean. Use proper torque specifications for M10-1.25 bolts and studs to avoid over-tightening or stripping threads. Zinc yellow coating provides corrosion resistance but avoid using excessive anti-seize compounds that may interfere with torque readings. This kit does not include washers or springs, so verify if your application requires additional components.

Dorman provides standard replacement grade hardware designed to meet or exceed OEM specifications for exhaust manifold fasteners. The metal construction and zinc yellow finish offer durability in high-temperature exhaust environments.
