Step-by-Step Installation Guide
Step 1: Prepare Your Workspace
Start by ensuring your workspace is clean and organized. Park your Oldsmobile 442 on a flat surface and engage the parking brake. If necessary, use jack stands to elevate the vehicle for better access.
Step 2: Remove the Old Exhaust Manifold
Begin by disconnecting the battery to prevent any electrical issues. Then, remove the old exhaust manifold by following these steps:
- Unbolt the exhaust pipes from the manifold.
- Remove any heat shields or brackets that may obstruct access.
- Carefully unbolt the manifold from the engine block.
- Remove the manifold and any remaining gaskets.
Step 3: Prepare the New Headers
Before installing the new Hooker or Borla headers, ensure they are clean and free of debris. Install the new header gaskets onto the engine block, making sure they align properly.
Step 4: Install the New Headers
Carefully position the new headers onto the engine block. Align the bolt holes and insert the header bolts. Hand-tighten the bolts to secure the headers in place.
Step 5: Torque the Header Bolts
Using a torque wrench, tighten the header bolts to the manufacturer’s specifications. This step is crucial to ensure a proper seal and prevent leaks.
Step 6: Reattach the Exhaust Pipes
Reconnect the exhaust pipes to the new headers. Make sure all connections are secure and free of leaks. If necessary, use new clamps to ensure a tight fit.
Step 7: Reconnect the Battery
Once everything is secured, reconnect the battery. Start the engine and listen for any unusual sounds that may indicate a leak or improper installation.
