Installing Hooker headers on your classic Mopar can significantly enhance your vehicle’s performance by increasing torque and improving exhaust flow. This step-by-step guide will walk you through the installation process, ensuring that you achieve the best results. Before you begin, make sure you have all the necessary tools and parts at hand.
Tools and Materials Needed
- Hooker headers specific to your Mopar model
- Socket set
- Wrench set
- Torque wrench
- Gasket scraper
- New exhaust gaskets
- High-temperature exhaust sealant
- Safety glasses
- Gloves
- Jack and jack stands
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Safety should be your top priority, so wear gloves and safety glasses throughout the process.
Step 1: Prepare Your Vehicle
Begin by lifting your Mopar using a jack and securing it with jack stands. This will provide you with enough clearance to work comfortably under the vehicle. Make sure the parking brake is engaged, and the engine is turned off.
Step 2: Remove the Old Exhaust Manifold
Locate the exhaust manifold on your Mopar. Using a socket set, carefully remove the bolts securing the manifold to the engine block. Be cautious as the bolts may be rusted or corroded. If necessary, use penetrating oil to loosen them.
Once all bolts are removed, gently detach the manifold from the engine. You may need to wiggle it slightly to break the seal. Set the old manifold aside and clean the surface of the engine block with a gasket scraper to remove any old gasket material.
Step 3: Install New Gaskets
Before installing the Hooker headers, place the new exhaust gaskets onto the engine block. Ensure they are aligned properly with the bolt holes. This will create a tight seal once the headers are installed.
Step 4: Position the Hooker Headers
Carefully position the Hooker headers onto the engine block, aligning them with the new gaskets. Make sure that all bolt holes are accessible and that the headers fit snugly against the gaskets.
Step 5: Secure the Headers
Using the provided bolts, begin securing the Hooker headers to the engine block. Start with the center bolts and work your way outwards to ensure an even fit. Use a torque wrench to tighten the bolts according to the manufacturer’s specifications, typically found in the installation manual.
Step 6: Install Exhaust Pipes
Once the headers are secured, it’s time to connect the exhaust pipes. Depending on your Mopar’s setup, you may need to cut or modify the existing exhaust system to fit the new headers. Use a high-temperature exhaust sealant on the joints to prevent leaks.
Step 7: Double-Check Your Work
Before lowering your vehicle, double-check all connections and bolts to ensure everything is secure. It’s crucial to verify that there are no loose components that could lead to exhaust leaks or damage while driving.
Step 8: Lower the Vehicle and Test
Carefully lower your Mopar back to the ground and start the engine. Listen for any unusual sounds that may indicate a leak or improper installation. Allow the engine to run for a few minutes, then check for any signs of exhaust leaks around the headers and connections.
Conclusion
Installing Hooker headers on your classic Mopar can greatly enhance its performance and torque. By following this step-by-step guide, you can ensure a successful installation that will improve your driving experience. Enjoy the increased power and sound of your newly upgraded exhaust system!
