The difficulty in accessing those plugs stems from their location near the firewall. Getting to them usually involves:
* Using the right tools: A spark plug socket with a swivel head or a flexible extension is essential. This allows you to maneuver the socket around the engine components without directly forcing anything. A ratchet with a long handle also helps.
* Removing obstructions: Sometimes, carefully removing or moving certain components (like a wire harness or vacuum line) can provide more clearance. Before disconnecting anything, take pictures or consult a repair manual to ensure you can reassemble everything correctly.
* Working from different angles: You might need to approach the plugs from various angles, using the swivel and extension to reach around obstacles.
* Using a mirror: A small mirror can be helpful to see exactly where the plug is and ensure the socket is properly seated.
If you're having significant difficulty, don't force anything. Forcing a spark plug socket can damage the plug, its threads in the cylinder head, or even strip the socket. Consider:
* Consulting a repair manual: A Haynes or Chilton manual for your specific vehicle model will have detailed instructions and diagrams showing the best approach.
* Seeking professional help: A mechanic will have the tools, experience, and expertise to access and replace the plugs safely and efficiently. This is often the most cost-effective solution in the long run, avoiding potential damage.
In short, focus on using the right tools and techniques to work *around* the obstacles, not on trying to move the engine.
