Installing Patriot Exhaust H8031 Sprint Car Headers can significantly boost your vehicle's performance. Here's a step-by-step guide to help you through the process:
-
Preparation and Removal:
- Begin by disconnecting the negative battery cable for safety.
- Remove the spark plugs and carefully label and detach all spark plug wires.
- Disconnect the existing exhaust manifolds from the head pipes and remove the manifolds.
- Thoroughly clean the cylinder head surfaces, removing old gaskets and any carbon deposits to ensure a proper seal.
-
Header Installation:
- Test-fit each Patriot Exhaust header, checking for clearance around motor mounts, lines, hoses, steering shafts, and linkages.
- Install the headers using the provided gaskets and header bolts. Applying anti-seize compound to the header bolts is recommended, especially when installing on aluminum heads.
- Tighten the header bolts evenly, starting from the center and working outwards. This ensures even pressure and a good seal.
- Reinstall the spark plugs and reconnect the spark plug wires to their correct positions.
- Make sure all wiring, brake lines, and hoses are clear of the headers and other exhaust components to prevent damage.
- Reconnect the battery cables.
-
Important Checks:
- Verify that brake lines, transmission lines, and fuel lines are clear of the headers.
- Ensure there's adequate clearance between spark plug wires, battery cables, and other electrical components and the headers.
- If the dipstick tube was removed, make sure it's properly reinstalled.
- Double-check the tightness of all bolts, brackets, and accessories.
-
Post-Installation and Startup:
- Start the engine and let it run until it reaches operating temperature. Check for any unusual noises or exhaust leaks.
- Once the engine is warm, stop it and re-tighten all header bolts. It's crucial to periodically check and tighten the bolts after the initial installation to maintain a tight seal.
