Step 1: Prepare the Car
- Park your car on a level surface and apply the parking brake.
- Allow the engine to cool down if it has been recently running.
Step 2: Raise the Car
- Use a jack and jack stands to lift the front of the car and provide safe access underneath.
- Ensure the car is stable and well-supported before proceeding.
Step 3: Locate the Exhaust Components
- Look under the car and identify the front exhaust components, including the exhaust manifold, catalytic converter, and front exhaust pipe.
Step 4: Disconnect the Oxygen Sensor
- Locate the oxygen sensor where the exhaust manifold meets the catalytic converter.
- Disconnect the electrical connector for the oxygen sensor.
Step 5: Remove the Exhaust Manifold
- Use a socket wrench to loosen and remove the bolts or nuts that secure the exhaust manifold to the engine block.
- Be careful not to drop any bolts or nuts into the engine compartment.
Step 6: Remove the Catalytic Converter
- Locate the catalytic converter, usually situated after the exhaust manifold.
- Remove the bolts or nuts that hold the catalytic converter to the exhaust manifold and the rest of the exhaust system.
Step 7: Remove the Front Exhaust Pipe
- Disconnect the front exhaust pipe from the catalytic converter by removing the bolts or nuts.
Step 8: Install the New Exhaust Components
- Position the new front exhaust components in place.
- Start by attaching the front exhaust pipe to the catalytic converter.
- Then, install the catalytic converter and secure it to the exhaust manifold.
- Finally, attach the exhaust manifold to the engine block.
Step 9: Reconnect the Oxygen Sensor
- Reconnect the electrical connector for the oxygen sensor.
Step 10: Lower the Car
- Carefully lower the car from the jack stands and remove the jack.
Step 11: Test the Exhaust
- Start the car and let it run for a few minutes.
- Listen for any unusual sounds or leaks from the exhaust system.
- If everything sounds and looks normal, the front exhaust replacement is complete.
Remember, working with exhaust systems can involve hot components, so take necessary precautions and follow safety guidelines. If you're not comfortable with any of the steps, it's best to consult a professional mechanic or refer to the specific service manual for your Peugeot 307 model.
