Which vehicles does this hardware kit fit and how do I confirm fitment?

The kit is intended as a direct replacement for specific vehicles and engine combinations; it is not universal. Confirming fitment requires entering your vehicle make, model and trim into the seller's garage or compatibility tool before ordering.

• Designed to match the original fastener set for listed vehicle applications.
• Check the vehicle compatibility tool or product fitment table before purchase.
• Contact the seller or reference OEM part numbers if uncertain about fit.

How should I install the Dorman exhaust manifold hardware to avoid issues?

Install using the manufacturer-specified torque sequence and values to ensure proper sealing and long-term reliability. Replace any exhaust manifold gasket at the same time and use anti-seize or thread locker only as recommended for the specific fastener and vehicle.

• Follow factory torque specs and tightening sequence to prevent warping or leaks.
• Replace gaskets and inspect mating surfaces for damage before installation.
• Use anti-seize or lubricants only when appropriate to the vehicle service manual.
